  • SQL Server 2008 Bring Database Online trying to open a file from a drive that doesn't exist

    - by Nai
    This is my error I am facing TITLE: Microsoft.SqlServer.Smo Set offline failed for Database 'Go3D_Retailer ------------------------------ ADDITIONAL INFORMATION: An exception occurred while executing a Transact-SQL statement or batch. (Microsoft.SqlServer.ConnectionInfo) Unable to open the physical file "E:\Program Files\Microsoft SQL Server\MSSQL10.MSSQLSERVER\MSSQL\DATA\ftrow_Go3D_catalog.ndf". Operating system error 2: "2(failed to retrieve text for this error. Reason: 15105)". Database 'Go3D_Retailer' cannot be opened due to inaccessible files or insufficient memory or disk space. See the SQL Server errorlog for details. ALTER DATABASE statement failed. (Microsoft SQL Server, Error: 5120) Background to this error I've been trying to move my destination logshipping database to another physical server for analysis purposes. Because I do not have domain keys and active directory set up, I had to hack my process by using the same username/password for both the source and destination servers to get the process to work. Following that, I used this guy's solution to move the destination database to another server. However, this error occurs when I try to bring the database back online. I don't have an E drive on my server and I have no idea why it's trying to open a file from E drive. I have over a 100gb left on my hard disk so it's definitely not a space issue. This sounds like a bug... Any ideas?

  • How to check DVD integrity at max read speed of DVD writer

    - by ashishsony
    I need to check the integrity of burned DVDs so that I can be sure about my backed-up data. I use DL-DVDs to take the backup. Earlier I used VSO Inspector software for the same but the day I switched to DL-DVDs the VSO Inspector gives me errors upon checking. I think the errors are because the switching of layer writing involves some dummy data somewhere. Secondly, it's damned slow for checking. I believe if there is a utility that can read all files (not the disk surface) and report if some files are unreadable would do the job. But it should be quick! Nobody wants to sit for disk checking for 3-4 hours after a quick 30 min data burn! I am looking for such a utility on Windows or Linux. Even scripts (python, etc) will do. I just want to be assured that the data is safe. Can someone help me in this? Thanks.

  • Problems with Windows 7 restore

    - by Chris Lively
    My WD raptor 150 failed with a nice clicking noise. So, I picked up a velociraptor 300 and popped it in. I had windows set to do a full system backup nightly, so I figured the recovery ought to go easily. Well, it isn't. It is currently stuck on a screen that says: "Windows is restoring your computer from the system image. This might take from a few minutes to a few hours" Below that is a rather large progress meter with maybe the first block filled in. Below that is a message that says "Restoring disk (C:)..." It's been that way for over an hour. The first time around, I gave up after 2 hours. I then booted into the system recovery options and went to a command prompt and ran a chkdsk on the new drive. It showed several file inconsistencies and not much else. I ran a chkdsk /f on it and tried again... Which is where I'm at now. I can't see that the restore process should take this long before. Any ideas? UPDATE After 10 hours, it's still on "Restoring disk (C:)" and the progress meter is at roughly 5%. I'm guessing at the 5% as there isn't an actual number or anything else that I can look at showing what it's actually doing. The backup contains roughly 120GB of data. How slow is windows restore?

  • Drobo-like linux file server - how do I do it?

    - by John Hunt
    I've been pondering for a long time about how I can set up a server which operates much like the Drobo storage thing. The reasons I don't actually want a drobo is because I've heard scare stories, plus I'd like to do this on the cheap. So ideally I'm looking for something like lvm so I can create a logical volume that spans many hard disks of varying sizes... obviously that only offers redundancy if I put the LV on a raid array (as far as I know..) I have however been reading about technologies such as Microsoft's drive extender which duplicates files at the filesystem level and makes sure that the mirrored files are on a different phyiscal disk.. does anyone know or recommend a filesystem or method like this as it'll hopefully make much better use of the space available than raid ever could. Performance isn't an issue, I'd just really like to make the most of the hard disks I have lying around whilst having a bit of redundancy incase a disk dies. I understand full well that this is no replacement for a backup, but I'll only be storing files of medium importance and using the nas itself as a backup of my main pc and other systems. Thanks in advance! I'm hoping zfs or btrfs or something can do something clever for me :)

  • trouble shooting ntfs-loop-xen combination in wubi based grub of Ubuntu

    - by Registered User
    Here is a situation I installed Ubuntu on a laptop using Wubi in Windows 7 drive.*The laptop is not mine.*I have installed and things worked by now perfectly without any problem.We are trying to set up a Xen (virtualization)environment in this laptop. After setting up every thing cleanly.When I needed to boot with following grub entries menuentry "Xen Linux 2.6.32.27" { insmod ntfs set root='(hd0,2)' loopback loop0 /ubuntu/disks/root.disk set root=(loop0) multiboot /boot/xen.gz module /boot/vmlinuz-2.6.32.27 dummy=dummy root=/dev/sda2 loop=/ubuntu/disks/root.disk ro console=tty0 module /boot/initrd.img-2.6.32.27 } I got error file not found error unknown command 'multiboot' error unknown command 'module' error unknown command 'module' Now to dig this issue further I reboot the machine and go to grub command prompt and manually pass on each of the above parameters which you see in the grub entry when I reached grub> insmod multiboot then I got following message on screen error:file not found. It looks like this wubi+ grub setup has just enough modules to use loopback file on ntfs, but the ACTUAL /boot directory is on the loopback NOT ntfs (hd0,2). Therefore any attempt to read any files from (hd0,2) simply wont work, cause there's no file there.I need to use insmod multiboot and command multiboot and module which are available in grub on a normal install without Wubi.But since the laptop is not mine so I am not allowed to partition it and have to make it work in this situation only. While a normal Kernel is still booting? How can I get module multiboot in this Wubi based install.

  • Can't get past bootcamp Windows logo, freezes immediately after picking boot partition -- Windows 7

    - by cksubs
    Hi, I had a fine install of Windows 7 alongside Snow Leopard. I had a power outage, and Windows restarted. When I booted via the "Hold Option" sceen, it started hanging at the grayscale "Windows logo" (squares) that comes up after picking the Windows drive from the bootcamp loader (the Windows version of the grayscale Apple logo when OS X loads). I think this happened once before, and installing rEFIt helped. I did that, but it continued to hang at the same point. I finally got fed up with it and erased the Windows partition via Disk Utility. I then reinstalled Windows 7 x64 from DVD to the fresh partition. Seemed fine. Ran Windows Update then restarted. FFFFFFFFF. Hangs in the same place. What can I do? Like I said, I already have rEFIt installed. Booting the Windows 7 install CD results in the same infinite loading error. I don't have a spare Snow Leopard disk handy.

  • Backing up default windows installation with dd from linux running on another partition - is this fe

    - by Marek
    I am preparing to reinstall my system. I am thinking about creating a multi boot with a linux distro+Windows 7 to choose from when starting up. I would love to be able to skip all the hassle of reinstalling Windows and all programs when it starts becoming too slow in the future, thus I would like to mirror my fresh Windows system partition with some programs preinstalled. I am thinking about installing Ubuntu, making a partition for windows, installing windows with the basic environment (Visual Studio, Office, etc.) then booting into Linux and making an image of the windows partition with dd. I am not familiar with linux at all so I am a little afraid something may go wrong along the way. Is it possible to do it this way? Will I be able to partition my existing disk for multi boot easily after I install Ubuntu? Will I be able to recover the Windows partition easily using dd when I will need to re-create a fresh windows partition in the future? What other (better) approach can you recommend to achieve the goal of easy disk mirroring (for free)?

  • Can I trick Carbonite into backing up an external hard drive?

    - by Brian
    I use Carbonite to back up my PC (Windows XP). We were running low on disk space on our home PC (down to 15 GB), so I went out and purchased an external hard drive. However, Carbonite will not back it up. Is it possible to set up Carbonite to backup an external hard drive? I just want the external drive to be extra disk space. From their FAQ: The current version of Carbonite backs up only the files that reside on permanent hard drives on your computer. It will not back up network drives, external drives, and NAS (network accessed storage) drives. If there are files on a remote drive that you wish to include in your Carbonite backup, you should copy the files to a folder on your local hard drive. If the files are on a shared network drive, you could install Carbonite on the computer on which the network shared drive physically exists, and back the files up directly from that computer. Check back soon for a Carbonite service plan that will allow you to back up your external drives.

  • Ubuntu NBR karmic boot freezes at fsck from util-linux-ng 2.16

    - by Bluebill
    I have a netbook (emachine e250 - equivalent to an acer aspire one) and I have Ubunutu NBR 9.10 installed on it. Every other cold boot freezes at the following error message: fsck from util-linux-ng 2.16 There is no disk activity, no activity what so ever. I have left the machine sit for over an hour and nothing. It takes a couple of hard resets to be able to boot properly. Once it boots everything works great (wireless, suspend/resume, etc.)! I have spent the last couple of weeks researching the problem and the only thing that seems to work is setting nolapic in the boot string in grub - it boots every time. Unfortunately, nolapic disables the second core and causes problems with suspend resume. At first I thought it was an fsck problem with the first partition on the hard disk as it is a hidden ntfs partition containing the windows xp recover information. So in /etc/fstab I set the partition so that it would be ignored by fsck. This didn't seem to do anything. I have these partitions: /dev/sda1 - an ntfs recovery partition /dev/sda2 - /boot /dev/sda3 - swap /dev/sda5 - / /dev/sda6 - /home I am running kernel version 2.6.31-19-generic and have all the patches (as indicated by update manager). I also have no splash screen so I can see the boot progress. I have only been using NBR since January, I have been using Ubuntu on my desktop since last June (2009-06). What logs should I be looking at? Is there a log for failed boots?

  • How to install Windows with no CD drive boot option in BIOS?

    - by Kris Hollenbeck
    I have a new computer which I built from scratch and I am trying to install a copy of Windows Vista on it. I am able to get to the BIOS and change the boot options which are as follows.. -Built-in EFI Shell -SATA: ST31000528AS I have searched around for and everything I find says to boot from the CD rom. However, as you can see. That is not an option for me. So I am wondering if there is another way around this? Is it possible to boot the Disk from the EFI Shell? Any help is much appreciated. Thanks EDIT: I have tried this.. http://technet.microsoft.com/en-us/library/dd744321%28v=ws.10%29.aspx UPDATE: I managed to make my USB bootable via the BIOS and I have copied my windows Vista disk onto my USB via drag and drop. However I am still not able to get the windows install to start. Also I have tried booting it from the EFI shell using the following command.. blk6: blk6:\> \EFI\BOOT\BOOTX64.EFI Still no luck..

  • Can't write to samba share

    - by Tiddo
    I try to setup a samba file server, but whatever I do I can't get write access to work (reading works fine). This is my current situation: I have a local fileserver with 3 harddisks mounted at /mnt/share/disk<nr>. 2 of these use the ext4 filesystem, the third one is ntfs. This file server runs Fedora 18 32-bit. The root folders of these harddisks are owned by superman:superman, and testparm outputs the following: [global] workgroup = WORKGROUP netbios name = FILE_SERVER server string = Samba Server Version %v interfaces = lo, eth0, 192.168.123.191/8 log file = /var/log/samba/log.%m max log size = 50 unix extensions = No load printers = No idmap config * : backend = tdb hosts allow = 192.168.123. cups options = raw wide links = Yes [share] comment = Home Directories path = /home/share/ write list = superman, @users force user = superman read only = No create mask = 0777 directory mask = 0777 inherit permissions = Yes guest ok = Yes I've tried a lot to get this to work: the disk are chmodded to 777, I've tried turning off selinux, I've added the samba_share_t label to the disks and as can be seen in the above output I tried to make the smb config as permissive as I could, but still I cannot write to the share (tried from Windows 7 and another Fedora installation). What can I try to be able to write to the shares? EDIT: The replies I got so far are mostly concerned with the smb.conf. I have however tried a lot of different setup, ready made configs, and solutions to similar problems for the smb.conf file, so I suspect that the real problem is somewhere else.

  • How To Replace Laptop HDD Without Losing Data?

    - by Ishan
    Hello, I recently went to Dell Service center and they tell that HDD is faulty and needs to be replaced. I have a Studio 1457 laptop with 500 GB HDD and don't want to lose the data(purchased in May 2010, still under warranty). I have searched a bit and I think it may be best to use a disk imaging software for this task. However, I don't know about a good software. I have following steps in mind: Get a 1 TB External HDD. Make an image of existing 500 GB HDD and store data on external disk. Install new HDD and install a brand new Windows copy and then install the software on it. Using the same software I used to make image, restore the old HDD image on new one. However, I have some questions in mind. First, is this possible? Second, I live in a country where piracy is a big issue and I am sure the support executive who will come to change HDD will have a pirated copy. But I have genuine Windows 7 Pro and don't want to lose it. Now, Dell does not supply and OS disks, so I can't install it on new HDD! If I follow above steps, which version of Windows 7 will be retained? One in the image(authentic) or one in the new HDD(pirated). I am ready to purchase a good software for this task and my budget is $50-60. Since laptop is under warranty, new HDD will be free. One last thing, I have created a Windows Migration file whose size is 70 GB. Can it be used to move from Windows 7 Pro to Windows 7 Pro?(In case I get a genuine copy of Windows 7!) Any other method to save all the data? Thanks in advance.

  • SATA Driver for Acer Aspire One D257

    - by Robert Niestroj
    i have a Acer Aspire One D257. In this netbook the hard disk is defect so i bought a new one. Now i want to reinstall Windows 7. Im using an external DVD Drive plugged into USB. The Windows 7 DVD is staring, Win7 setup is starting and when it comes to Hard Drive options it says that no drive was detected and i should try search for drivers. It shows me this window: Screenshot from web Now i cant find the right drivers for this netbook to continue with the installation. The laptop has the newest BIOS - 1.15, it is reset to factory default settings except that i enabled the Boot Menu prompt with F12. From the Acer Support Website i've downloaded the SATA AHCI Driver and the Chipset Driver. I unpacked both to a USB flashdrive in seperate folders. When i select the SATA AHCI Driver it does not find any drivers. When i uncheck the checkbox "Hide drivers that are not compatible with hardware on this computer" it shows one driver: Acer HWID (path_to\1.inf). When i continue with this driver i got an error message that says something like: No new devices found. Check if the driver files are on the installation disk. When i show him the Chipset Driver it sees a lot more driver. When i uncheck the checkbox "Hide drivers that are not compatible with hardware on this computer" it show some drivers: Intel N10 Family DMI Bridge Intel N10/ICH7 Family PCI Express Root Port Intel N10/ICH7 SMBUS Controller Intel N10/ICH7 Family USB Universal Host Controller Intel N10/ICH7 Family USB2 Enhanced Host Controller Intel N10/ICH7 Family Interface LPC Controller When i uncheck this checkbox i get a lot more drivers, and some SATA Drivers but the also do not work. I get the same error message as before. Can someone help me find a driver that should work or am i doing anything else wrong?

  • Can enabling a RAID controller's writeback cache harm overall performance?

    - by Nathan O'Sullivan
    I have an 8 drive RAID 10 setup connected to an Adaptec 5805Z, running Centos 5.5 and deadline scheduler. A basic dd read test shows 400mb/sec, and a basic dd write test shows about the same. When I run the two simultaneously, I see the read speed drop to ~5mb/sec while the write speed stays at more or less the same 400mb/sec. The output of iostat -x as you would expect, shows that very few read transactions are being executed while the disk is bombarded with writes. If i turn the controller's writeback cache off, I dont see a 50:50 split but I do see a marked improvement, somewhere around 100mb/s reads and 300mb/s writes. I've also found if I lower the nr_requests setting on the drive's queue (somewhere around 8 seems optimal) I can end up with 150mb/sec reads and 150mb/sec writes; ie. a reduction in total throughput but certainly more suitable for my workload. Is this a real phenomenon? Or is my synthetic test too simplistic? The reason this could happen seems clear enough, when the scheduler switches from reads to writes, it can run heaps of write requests because they all just land in the controllers cache but must be carried out at some point. I would guess the actual disk writes are occuring when the scheduler starts trying to perform reads again, resulting in very few read requests being executed. This seems a reasonable explanation, but it also seems like a massive drawback to using writeback cache on an system with non-trivial write loads. I've been searching for discussions around this all afternoon and found nothing. What am I missing?

  • Can't Install Win2k8 On KVM - Classic 0x80070013 error

    - by javano
    I am trying to install Win2k8 Std as a KVM guest on Debian Squeeze. As you can see from these screen shots; No drives are detected (I have blanked out a 20GB image for testing) - screenshot1 I am using this driver CD: - screenshot2 I have signed the Win7 driver (I assume this was the most appropriate one?) - screenshot3 I can now see an unpartitioned drive - screenshot4 But I can't create a new partition on here, getting the error code 0x80070013 - screenshot5 I have had this error code before but only on a physical server. If I remember correctly it was complaining because the disks were partitioned as GPT (because it was a server that was being re-purposed) so repartitioning with an MS-DOS table fixed that. This is a blank disk image though. What is wrong here, and how can I correct this? Thank you. UPDATE I have booted the VM with a Gparted-Live disk and formatted this volume with an MS-DOS partitioning scheme, and a single 20GB NTFS file system. Now when I boot the Win2k8 CD, load my drivers, I get a different error. As you can see at the bottom of screenshot6 "Windows cannot be installed on this hard drive space. Windows must be installed to a partition formatted as NTFS". Clicking format produces the error (0x80004005) on the screen, so I think this is still a driver issue because Windows can see the drive but not interact with it properly. Is that insane thinking?

  • Windows 7 boot problem on a Lenovo Thinkpad Z61m 9450HAG

    - by Matt Taylor
    I recently did a full upgrade of Windows 7 on my Thinkpad. Everything worked fine after up until the second reboot (the first reboot after some updates installed worked OK). At second reboot time the system would just black screen before the Windows logo appears. Disk/wireless/power/battery lights are all lit and the disk light is active (flickering). However, if I remove my battery and boot with just power it boots fine and quickly, and everything is OK. Any help on why this won't boot with battery plugged in is greatly appreciated. I need to take this battery out on the road/trains, etc. A little more detail on this story. The battery I had inserted when doing the (failed) boot was a long life battery. I have not tried inserting this battery when Windows is logged in. I have another (normal life) battery that I have charged up within Windows. It has just got to 100% and I am about to reboot with it in. I am using the Lenovo power manager to diagnose the battery - all seems OK. I will report back shortly as to the outcome. OK, so I chose the reboot option from within Windows, the machine seemed to shutdown okay, but then stalled. It didn't turn off completely and didn't reboot, but just sat, with the fan humming, somewhere in between! I had to hold the power button in for a few seconds until the fan stopped and then hit the power button again to boot the machine from fresh. One good thing, with this battery (the normal one) it booted into Windows 7 the first time with a battery! So, now I have rebooting issues. I have 3 errors in the event log: A timeout was reached (30000 milliseconds) while waiting for the lxdxCATSCustConnectService service to connect. The lxdxCATSCustConnectService service failed to start due to the following error: The service did not respond to the start or control request in a timely fashion. The following boot-start or system-start driver(s) failed to load: cdrom Any thoughts?

  • Differential backup missing moved folders (flawed archive attribute logic)

    - by Max
    Recently I've discovered that my backup system it flawed: there are situation where various files/folders are missed. I do my backup from local disk to a network NAS. I use Cobian backup, and I have setup the backup software to create one full backup every week, and one differential backup every day. Now, the backup software (to my knowledge any backup software work this way) decide the files that go in the differential backup by looking at the file archive attribute. If the attribute is set, then the file go in to the backup. Now, when you move a file to a new location, on Windows systems, the archive attribute get set and the file is included in the backup, and that's fine... but when you move an entire folder, no archive attribute is set, nor on the folder, nor in any files inside the folder, so the moved folder isn't included in the differential backup! So, if you have a full backup plus a differential backup, and you moved folders around... then it's impossible to reconstruct the original files/folders structure starting from the full+differential backup, because the backup software didn't include the moved folders in the differential backup. So my differential backup are useless... Why does windows set the archive attribute when moving a file, but not when moving a folder? How can I deal with this issue? Is there a way to create a differential backup that works as it's supposed to do? Doing full backup every day is not practical, because the changed data is about 0.1% at day (by using a differential backup I can keep 4 weeks of files history without using too much disk space.)

  • Install Windows 7 from ISO image

    - by Albert
    Hi, I have an ISO file of the Windows 7 DVD and I want to install it on my PC which currently only runs Linux. I don't have any DVD drive. I have some unpartitioned space on one disk where I want to install it in. When I am doing this for Linux, I usually just create the partitions from the running system, format them, mount them, copy files over, chroot into it, setup the stuff and I can boot into it (or I use some of the uncountable available scripts which do exactly that automatically). However, I have no idea how to do the same thing with Windows. So far, I tried with VMware, i.e. I gave it direct full access to the disk where I want to install it in, installed it there, then tried to boot natively into it. The Windows logo showed up but after maybe 3 seconds or so, it crashes. Safe mode also crashes. I already expected that this probably would exactly behave the way it does right now because I have heard that Windows is quite sensible about hardware changes (i.e. the VMware hardware and the real hardware). However, how can I fix it now that it works? Or I could also just delete it again and try just over. But how exactly? I also searched for ways to boot directly into an ISO file. There seem to be ways to do that via GRUB (and maybe some additional boot loader), although quite complicated. I already tried one method (GRUB: map ...iso (hdX)), however, that didn't worked. Also, even if it does work, I will get into trouble when I boot into the newly installed Windows and it requests for the DVD (because it does that at the first boot into the new system). Seems all quite complicated. Isn't there some easy way like I would do it for Linux? Or what would be the easiest way to get what I want?

  • Allignment of ext3 partition on LVM RAID volume group

    I'm trying to add a partition on a LVM that resides on a RAID6 volume group and fdisk is complaining about the partition not residing on a physical sector boundry. My question is, how do you calculate the correct starting sector for a partition on a LVM? This partition will be formated ext3.

  • diskmgmt.msc: Cannot delete volume from USB

    - by Notinlist
    I have an USB drive with about 8GB of size. It has a single partition of size 169MB. Don't know why, I got it that way. I wanted to delete this small (FAT32) partition and create a single NTFS volume on it. First, I noticed that the "Delete volumme" option is disabled (grayed out). I then tried "Change drive letter and paths..." and removed "F:", that way I made sure that there are no open files on it. The "Delete volume" was still disabled. Then I got suspicious, and right clicked on the "Unallocated" area and I noticed that I did not have any useful option. All "New * volume" items are disabled. I exited from diskmgmt.msc, ran a cmd.exe with administrator privileges, ran the diskmgmt.msc from it, same experiences. Why can't i do anything with this disk? I've read some advices about downloading some alternative free software, but I rather not do it if possible. I still hope that Windows 7 Enterprise 64bit alone can reinitialize an USB drive without external help. I also cannot do anything with my other 8GB pendrive. It's all an NTFS volume, I tried to delete it, but the option is disabled here too. Maybe I have some settings somewhere that prevents my from partitioning USB disks. (I have the freedom to remove my D: partition which is the second - not counding the "System reserved" - on my SSD disk.)

  • Coffee spilled inside computer, damaged hard drive

    - by Harpreet
    Today coffee spilled over my table, and some of it (very less) reached the PC case placed under the table. I think little bit of it got inside the PC case through the front. As that happened the fan started running very fast and made noise. I tried to restart to see if it becomes fine, but the computer didn't start again. First it gave an error of "Alert! Air temperature sensor not detected" and didn't start. Next I tried again multiple times of starting the computer but then it gave some memory error. I was not able to start the computer. Incase there's a problem in hard disk or something related to memory, is there any way we can extract our work or data? I am scared if I am not able to extract my work in case some problem occurs like that. What options would I have? Help!! EDIT: I have attached the photo here and you can see the area spilt in red circle. The hard drive electronics have been affected and internal speaker may also have been affected. Any advise on cleaning and if hard drive can work? EDIT 2: Are there any professional services offered to extract data from blemished hard disk, like this one, in case I am not able to run it personally?

  • Determining the Source of a Given File System Mount on Unix [migrated]

    - by phobos51594
    Background Recently I have run into a bit of a snag on my home FreeBSD server. I recently upgraded it to the latest stable release, and I have noticed some strange behavior with the /var partition. Originally, I had the system configured such that /var had its own partition with /var/run and /var/log in memory disks (/tmp, too). After the upgrade, I notice there is a new, fourth memory disk mounting directly to /var that I had not set up manually and is not in my fstab. It is only 28 megs or so in size and is causing problems when trying to update my ports collection. The ramdisk mounts atuomagically at boot and cannot be unmounted while in multi-user mode. If I drop to single user mode, I am able to unmount it without issue, however rebooting causes it to pop right back up. System specifications have been included at the end of the post. Question Is there any way to determine exactly what is mounting a given memory disk (or any filesystem, for that matter) after it has been mounted? Alternately, does anybody have any ideas what might have caused the new /var ramdisk to pop up?

  • Is UPS worthwhile for home equipment?

    - by Jon Skeet
    Over the years, I've had to throw away a quite a few bits of computing equipment (and the like): Several ADSL routers with odd symptoms (losing wireless connections, losing wired connections, DHCP failures, DNS symptoms etc) Two PVRs spontaneously rebooting and corrupting themselves (despite the best efforts of the community to diagnose and help) One external hard disk still claiming to function, but corrupting data One hard disk as part of a NAS raid array "going bad" (as far as the NAS was concerned) (This is in addition to various laptops and printers dying in ways unrelated to this question.) Obviously it'll be impossible to tell for sure from such a small amount of information, but might these be related to power issues? I don't currently have a UPS for any of this equipment. Everything on surge-protected gang sockets, but there's nothing to smooth a power cut. Is home UPS really viable and useful? I know there are some reasonably cheap UPSes on the market, but I don't know how useful they really are. I'm not interested in keeping my home network actually running during a power cut, but I'd like it to power down a bit more gracefully if the current situation is putting my hardware in jeopardy.

  • VMWare Raw Device Mapping Not Working

    - by George H. Lenzer
    While I'm waiting for VMWare support to get back to me, I thought I'd ask here. I have a 400 gig LUN presented from a fiber channel SAN to my VMWare host. It's legacy from another virtualization platform and I need to keep it as is to avoid a long period of downtime. I formatted my VMFS3 datastore with 4 meg blocks to allow up to 1 TB disks. Then I tried adding my 400 gig disk as a raw device in physical compatibility mode. I get the error: "File is larger than the maximum size supported by datastore 'Base Test'. [Base Test]VMTEST01/VMTEST01_2.vmdk Originally I had the VMFS datastore formatted with 1 meg blocks which was the cause of this problem since the largest disk allowed would be 256 gigs. But I deleted the data store and then reformatted with 4 megs blocks. I've also tried using virtual compatibility mode for the raw device but it still fails. Does anyone have any suggestions? I've been waiting for a little over a week for VMWare, but that's fine because I'm not yet a paying customer. I'm still in the eval phase.

  • 2011 i7 Macbook Pro unable to boot from any Windows CD?

    - by Craig Otis
    I'm encountering issues installing Windows alongside my Lion install. I'm attempting to install from the internal SuperDrive, after using Boot Camp to partition what was a single, HFS+ volume. When holding down Option at boot, the CD appears in the startup list, but upon selecting it, I get a gray screen for 5 minutes, then a flashing white folder. I tried installing rEFIt and using this to boot the CD, but I receive an error about "Not Found" being returned from the "LocateDevicePath", and a mention of the firmware not supporting booting using legacy methods. In the Console, when opening the StartupDisk preference pane (which never presents the CD as a selectable option), I see: 11/25/11 4:39:31.159 PM System Preferences: isCDROM: 0 isDVDROM:1 11/25/11 4:39:31.159 PM System Preferences: mountable disk appeared: /Volumes/GRMCPRFRER_EN_DVD 11/25/11 4:39:33.214 PM System Preferences: - So far so good, passing disk to System Searcher. 11/25/11 4:39:33.218 PM System Preferences: OSXCheck: No boot.efi in System Folder or volume root. 11/25/11 4:39:33.220 PM System Preferences: WinCheck: Not a valid windows filesystem: /Volumes/GRMCPRFRER_EN_DVD 11/25/11 4:39:33.220 PM System Preferences: WinCheck: Not a valid windows filesystem: /Volumes/GRMCPRFRER_EN_DVD I'm at a loss here. I've done my research, but it sounds like most of the rEFIt errors of this nature are caused by installing from a thumbdrive, or an external drive. I'm using the internal SuperDrive. Also, I've tried this with two different disks: A Windows XP SP2 CD A Windows 7 x86 DVD Both are disks I've had around for years, and I've used them reliably in the past. The system is an early 2011 15" Macbook Pro, all firmware updates installed.
