• DFSR - What happens when one server gets maxed out?

  - by Jared

  What happens when one server in a DFSR pool maxes out its disk space? I am at the very beginning of my research in DFS/R and this struck me. I plan on implementing this on one server with RAID1 (160GB) and on another server with a RAID5 (500GB). What happens when my 1st server with 160GB disks, run out of space? Will it spill over to the 500GB server? Is it advisable at all to even have the RAID1 server in the DFSR pool? Because the RAID1 server is also my Domain Controller. Hope you guys can help me out here (OS are Win2k3R2)

• What effect does RAID stripe size have on read-ahead settings?

  - by stbrody

  I'm trying to figure out the correct read-ahead values to set on a RAID10 array, and I'm wondering if the RAID stripe size should factor into my considerations. I've heard conflicting information about this in the past. I once heard that you should always set your read-ahead value to a multiple of the RAID stripe size, and never below the stripe size, because that is the minimum amount of data the RAID controller will ever try to read at once. Someone else told me, however, that setting read-ahead below the stripe size is fine, and can, in fact, increase the amount of parallel reads you can do across devices in the array, increasing performance and decreasing load on the array. So which is it? Do read-ahead settings that aren't multiples of the stripe size make sense or not?

• grep pattern interpretted differently in 2 different systems with same grep version

  - by Lance Woodson

  We manufacture a linux appliance for data centers, and all are running fedora installed from the same kickstart process. There are different hardware versions, some with IDE hard drives and some SCSI, so the filesystems may be at /dev/sdaN or /dev/hdaN. We have a web interface into these appliances that show disk usage, which is generated using "df | grep /dev/*da". This generally works for both hardware versions, giving an output like follows: /dev/sda2 5952284 3507816 2137228 63% / /dev/sda5 67670876 9128796 55049152 15% /data /dev/sda1 101086 11976 83891 13% /boot However, for one machine, we get the following result from that command: Binary file /dev/sda matches It seems that its grepping files matching /dev/*da for an unknown pattern for some reason, only on this box that is seemingly identical in grep version, packages, kernel, and hardware. I switched the grep pattern to be "/dev/.da" and everything works as expected on this troublesome box, but I hate not knowing why this is happening. Anyone have any ideas? Or perhaps some other tests to try?

• Ubuntu 12.04 Netinstall URL? Xen Host

  - by notFound

  Well I have an Xen server, I've got a CentOS container up fine but a friend of mine wants (oh god) Ubuntu Server 12.04, why he can't use Debian is beyond my understanding. But anyways, I can't remember how I installed the CentOS container but I'm giving virt-manager a try now, since I don't have a disk image already the only option is to get a Network Install URL since I'm using PV. So does anyone know what I should type in there, if it was CentOS I could easily type http://mirror.centos.org/centos/6.2/os/i386 for example. The furthest I've got in finding a suitable URL is http://archive.ubuntu.com/ubuntu/dists/precise/ but that of course wont work. Any ideas?

• Limiting Sybase ASE 15 CPU usage on VM

  - by reiniero

  I've set up a single CPU Sybase ASE 15.7 test/hobby/experimentation system on a Debian Squeeze x64 KVM VM. I notice the CPU load goes to 100% and stays there. Definitely not a Sybase guru, only interested to see if some programs I'm running work on the database. Looking at Sybase docs it seems ASE detects the machine is idle and then takes over all processing just waiting for a connection (and if needed, doing some housekeeping apparently). Normally that would be fine but as it is running in a VM it's taking away processor resources other VMs could use - and the increased fan noise of the PC near my desk annoy me. I've tried to remedy this: set the "runnable process search count" parameter from DEFAULT (2000 IRC) to 3 in /opt/sybase/ASE-15_0/SYBASE.cfg from http://sybase.reygrobellet.com/tutorials/install_sybase_vb/standalone04_configure_oralin11#TOC-Configure-kernel I added this to my /etc/init.d/sybase startup script: echo 0 /proc/sys/kernel/randomize_va_space (though I don't think it'll make much difference) How can I tell Sybase to "behave" and not hog the processor - I don't mind reduced performance.

• Apache has a 2GB file limit on a CIFS network drive?

  - by netvope

  Setup: A Windows and a Ubuntu Server are hosted in VMware ESXi I have a a 6GB file on a Windows share The Windows share is mount on Ubuntu with smbmount A symlink pointing to the 6GB file is created in a public_html directory, which is readable by Apache The problem: wget gets an error Connection closed at byte 2130706432. Retrying. after downloading 2130706432 bytes (exactly 2032 MiB, and is the same every time) Apache returns 206 Partial Content without showing any errors in the log Same error even if I download from localhost Similar error when Firefox is used instead of wget No error if I md5sum or cp the file on Ubuntu, suggesting that smbmount and the Windows Server are OK with 6GB files. No error if Apache serve a 6GB file from the local disk, suggesting that Apache has no problems handling 6GB files. Any ideas why Apache/symlink/smbmount/Windows would cause an error when used together? How can I fix the problem?

• specify temp folder for msi extracted files used for installation

  - by Binoj Antony

  I was recently installing Microsoft Windows SDK for Windows 7 and .NET Framework 3.5 SP1 to create my build server on a VM (Windows 2003 R2 Std), I was wondering that it would be nice to specify the temporary folder for the files being extracted by MSI for use during the installation. This should ideally work for any MSIs. I have some more virtual hard disks I have attached to this VMs, to point the temporary folder for MSI to one of these virtual hard disks would be quite productive since I can remove/discard this virtual hard disk later. Compacting the C drive VHD is a pain, and does not always reclaim space correctly. I tried changing the %temp% and tmp environment variable with no effect? Or is there any concrete/alternative solution to this type of problem? References: TempFolder Property ?? Windows Installer Wiki

• Would firewire networking be better than 100Megabit ethernet?

  - by Josh

  My office network has a fully switched 1000Megabit ethernet network. I have an Apple iMac with a Gigabit NIC and FireWire, and a Compaq laptop with a 100Megabit NIC and a 4-pin FireWire interface. Accessing my office's shared drives using my laptop is (obviously) much loswer using my laptop than my iMac. Would I see a noticeible performance boost if I enabled Internet Connection Sharing on my iMac and shared the private ethernet network from my iMac with my laptop over FireWire? FireWire is 480Mbit/sec, right? So would I see roughly 4x speed improvement with such a setup?

• Folder redirection save times are awful slow

  - by wbmeu

  I recently set up folder redirection for Documents on Server 2008, but it's painfully slow at the moment. My users are all using Visual Studio 2010, and a save takes 20-30 seconds (whereas it used to take 2 seconds locally). I understand this is because they are being saved to the server, and that takes time (though I did think it would be faster over a gigabit link, with servers on the same network). I enabled offline files on the share, set the option to All files or folders, and enabled Optimize for performance. I thought that this would pull all the files down locally (which I think it did), allow local editing of said files, synchronizing them quietly in the background from time to time (which it does not do - saves right to the share). Is there any way I can speed this process up a bit? Any other tweaks I can do?

• Simple SQL Server 2005 Replication - "D-1" server used for heavy queries/reports

  - by Ricardo Pardini

  Hello. We have two SQL 2005 machines. One is used for production data, and the other is used for running queries/reports. Every night, the production machine dumps (backups) it's database to disk, and the other one restores it. This is called the D-1 process. I think there must be a more efficient way of doing this, since SQL 2005 has many forms of replication. Some requirements: 1) No need for instant replication, there can be (some) delay 2) All changes (including schemas, data, constraints, indexes) need to be replicated without manual intervention 3) It is used for a single database only 4) There is a third server available if needed 5) There is high bandwidth (gigabit ethernet) available between the servers 6) There isn't a shared storage (SAN) available What would be a good alternative to this daily backup/restore routine? Thanks!

• Missing over 100GB of Space on sda1 RHEL

  - by WifiGhost

  I have a server setup with a RAID 5 using (3) 500GB drives, 1 as a spare so unused in the RAID. So in my mind i start out with 990GB with the RAID 5 in place. When looking at DF or the built in disk space utility i only see a total of about 882GB, how can i find where the 100+GB went? How can i get it back? I've checked the RAID 5 BIOS and i see all the space. I've tried looking manually and through terminal commands with no luck.

• Laptop as server [closed]

  - by Parhs

  My client wants to use a cheap AMD E-300 ,5400 rpm disk,4gb memory laptop as a POS server and music player at the same time with dual screen. I couldnt convince him that this wouldnt be a good choice. The applications are a database a music player ,and the .net 4 application. I am afraid of performance issues. However the reasons for this choice is that laptop takes not much space ,easy dual screen for music player and application ,can easilly be replaced and that it will last forever as none of his laptops are ever broken. I believe that this is a good idea but i feel thats something wrong there. Do you believe that is an ok choice?

• "the user profile service failed the logon"

  - by crazybmanp

  "the user profile service failed the logon" i had gotten this error when trying to login last night. i looked it up online and found that this was caused by an error (that is still unfound, apparently) that is causing windows to mark profiles as backup, and that the best way to fix this error is to do a system restore from the repair your computer special boot option. what i would like to know is if there someone happens to know the cause of this error, as i would not like it to happen again. Computer specifications OS: Windows 7 hard-disk check completely clean "repair startup" scan and fix: clean, no problems virus scans with kaspersky: clean (while not the usual information for specifications, i felt this info was more important for this case, any other information can be asked for.

• KVM CLI install for CentOS 6.3 defaults to Minimal Install

  - by i.h4d35

  So I now I've installed KVM (and its associated tools and packages- libvirt, VMM etc.). On the GUI (i.e using the VMM), installation works as its supposed to. However, when I try to create a VM using the command line interface, the OS (I am working with CentOS 6.3) defaults to a Minimal Install instead of giving me options to choose from at the time of installation. I am trying to install using the following command: virt-install \ --connect qemu:///system \ --virt-type kvm --name testVM2 \ --ram 512 --disk path=/var/lib/libvirt/images/testVM2.img,size=8 --vnc \ --cdrom /media/db18de8e-0853-49fb-80de-5c794d58a46f/CentOS-6.3- x86_64-bin-DVD1.iso \ --network network=default Specifying the OS-type or the OS-variant parameters doesn't make a difference. Is there something that I am missing out on or some other parameter that I must specify? Thanks in advance.

• How do I maximize and check my gigabit transfer rate?

  - by J Penguin

  I'm trying to maximize my LAN transfer speed. LAN cards and switch are all gigabit on a CAT 6 cable. Modes are set correctly to 1000 full duplex. CentOS server Testing with ftp from both windows and fedora, I'm only having the speed around 11MB/s. On windows I notice that the first few seconds of file transfer I'm actually getting around 25MB/s before it drops to 11MB/s Can anyone please recommend me what my next step should be to increase this performance? Are there any utilities I can use to test the file transfer speed without taking hard drive speed into consideration? The only thing I know is the MTU which I will have to wait until the office hour is over before I can play with it. If there are anything else I should be aware of, please please let me know. Thank you!

• Can i enlarge os c drive of my windows 8?

  - by Sorgatz

  Last year I got a new Western Digital WD Blue 500GB HDD to replace my old drive. The first thing I did was to install latest Windows 8. While installing Windows 8 I created 3 partitions, C drive for the OS and others for storage. The OS partition is 120GB (which at the time I thought would be plenty big) but I'm now realizing its too small! I wonder if it's possible to re-size HDD partition without reformatting and re-install my Windows 8. So that is my question, Can i enlarge os c drive of my windows 8 without having to re-format? I've used the Norton Partition Magic and Disk Management to make this happen but there doesn't seem to be any options to make it happen. Thanks for any help you guys can give regarding my question. I've worked hard to optimize my current install of Windows 8 and would hate to start all over again.

• Where do I find a color profile for my MacBook Pro display?

  - by Jesse

  I installed Windows 7 on my MacBook Pro, overwriting OSX Lion. The screen has a blue tint due to lack of a calibrated color profile. I once used the "Color LCD" ICC profile from the OSX partition and it worked great, but I've since lost it since I decided to overwrite OSX completely. I tried the manual calibration in Windows 7 but I just can't seem to get it right like it was while using the color profile that was on the OSX partition. All Google tells me is where to find the ICC profile in OSX, and to copy it over. Do I have to reinstall OSX just for the color profile? Even if I do, where does the profile actually come from? Is it on the OSX disk, or is it somehow retrieved from the hardware itself? Is there a way to get it without reinstalling OSX? Thanks!

• Idle VMware Guests Resource Consumption

  - by Ravenor

  I want to setup a number of guests with multiple CPUs (4) and at least 4Gb ram running Ubuntu Linux. These machines will mostly be idle, but from time to time their workload will require all their resources, especially the CPU. The hosts are ESXi 5.x. The question is, am I right in thinking that the resource consumption of the machines when idle will be negligible? We know this true of disk and the CPU. The only concern left therefore is memory. Since ESX over-commits memory it makes sense that unused memory of any guest is paged out. If my thinking correct?

• OVF Tools error

  - by ToreTrygg

  Hello all, I am trying to use OVF tools 1.0 to create an .ovf appliance split to 4gbs. When I run the following command: ovftool --chunkSize=4gb vi://:@/?ds= e:\test\test.ovf everything starts off fine. It will got for about 15-16% then I get this message: "Error: unable to get NFC ticket for target disk". I have looked online, but cannot find anything that matches this problem. I am using Windows 2k3 as the ovf creation server, and I'm in a ESX 3.5 environment. The ovf must be split into 4gb chunks (or less) so they can be put onto DVDs. Also, when it is done it deletes the files it started to create. Any help would be greatly appreciated.

• Secondary drive corrupted/not reading

  - by Sebastian

  When I connect my Seagate Barracuda to the computer, it shows up on the list of drives in Windows Explorer, but right clicking on it crashes Windows Explorer, opening it won't do anything, and I cannot start disk manager when it is connected. Trying to search the drive also freezes Windows Explorer. I have tried to run CHKDSK on it, and it was "unable to read $J data stream" for the Usn Journal. Also, it was an internal drive, but I pulled it out and hooked it up externally so I could test if it was that drive causing the problems. Is there any way for me to copy the files off of the drive?

• Intel Core i7-4960HQ vs. 4850HQ (Haswell) [on hold]

  - by Timothy R. Butler

  I'm looking at the new MacBook Pros and trying to decide between the Core i7-4960HQ (2.6 GHz) and i7-4850 (2.3 GHz). I've found some synthetic benchmarks comparing them, but I haven't found a lot of data, so I'd appreciate any pointers to good comparisons for the Haswell family (especially these two processors). My cursory analysis seems to suggest there isn't a huge gain from the extra 300 MHz. I'd like to determine not only whether this is generally true, but also to figure out if the gains that are made in performance come at too high of cost. Is the 2.6 going to be pushing the limits of what can fit in a thin laptop without overheating? I've looked at some of Intel's documentation, but have not been able to determine what the normal and maximum operating temperature differences are for the models. In the past, there have been times that Intel's fastest models in a given range ran especially hot and/or consumed significantly more power compared to slightly slower models. Do those concerns factor into the current generation?

• external HDD with SATA & USB interface? [closed]

  - by GregH

  Anyone know of an external HDD that would have (in addition to USB) a SATA (eSATA) port/cable? i.e. Brand/Model Background - In one location I want to use it is I would like to increase the performance by cabling it directly to the PC SATA port, HOWEVER I don't want to have to open up the PC to do this each time. I was thinking of running a SATA cable out through the PC case so I just plug it directly into the external HDD in question. Perhaps it should be also externally powered too so I don't need to run a power cable out from the PC power supply.

• Remotely push DNS server to client via OpenVPN

  - by wishi

  Hi! When I try to push a DNS server via the OpenVPN server-config I don't get that server to be the first DNS server on the connected client system. It ends up being specified as an alternative DNS server. push "dhcp-option DNS 89.238.75.146" # DNS-Server 1 (local djbdns) To overcome certain network restrictions, if they're at place, I use 443 TCP. - That means that my DNS queries are sent via TCP (if I manually reconfigure the DNS server), which doesn't scale very well from a performance perspective. Are there any kewl solutions for that? Marius

• Restricting permissions to individual documents on SharePoint

  - by wahle509

  Here's what I'm trying to do: I would like to create a list of documents on a site in my company's SharePoint site. Each document should have specific user's permissions to view and edit it. For example: The list is for performance reports. John has his out there called "John_PR_09.docx". Only him and his supervisor should have permissions to view, edit, or do anything to it. And then another employee has hers out there with permissions for only her and her supervisor, and so on... I have tested this out with a document that I removed the groups and users from (since they inherit permissions from it's parent) and only gave my user account permissions to. I then asked someone else to try and open and she could, she even wrote "TEST" on the document and saved it. What am I doing wrong? I thought I stopped it from inheriting permissions from it's parent and only gave myself rights to edit it.
