• Resize a new database to predicted maximum size

  - by John Oxley

  Currently I have a SQL Server database which is about 2 Gb. I know over the next year it's going to grow to a maximum of about 10Gb. Hard drive space is not an issue in the slightest. Is there a down side to resizing the datafile to 20Gb now, then defragmenting the hard drive? Should I resize the log file to 1Gb as well? Something ridiculously large so that fragmentation doesn't happen there either. With this question I would like to avoid the datafile becoming fragmented on the disk itself, but I don't want to negatively impact performance.

• How to Completely delete my USB thumbstick?

  - by Roi

  I own a Kingston thumb-stick. I have installed a Google Chrome OS image to it so I could try it out. When it did so, it created 3 partitions (I backed everything and the software that installed Chrome OS delete my thumb-stick completely and created 3 partitions). Now I want to get it back to 1 partition but when I go to Disk Management, it will not let me "extend" the partition. I have tried different partitioning tools but they didn't recognize my thumb-stick anyway. I have also tried DiskPart to no avail. Is there any software that will completely format my thumb-stick so I would only have 1 partition?

• 8GB, but have to run Windows Xp (32 Bit). Anything I can do with the additional memory?

  - by user12889

  I ordered a new computer with 8GB RAM with the plan to run Windows 7, 64Bit. Turns out now, that I need to run a 32Bit OS (XP or 7) due to some software which does not run on 64Bit yet (not even with any of the available compatibility settings / modes). Is there anything I can do with the memory above 4GB in this scenario? I'm willing to consider creative solutions like running a hypervisor under XP that offers the memory as a RAM-Disk for swapping etc. ? The software that does not run on 64Bit is CISCO VPN (there seems to be a half-working solution for that) and CISCO IP phone / webcam integration "CISCO Unified Video Advantage" (there is apparently no solution for that).

• When NOT to use virtualisation? [closed]

  - by Nils

  When virtualisation was new, we tried to virtualized everything. Then came the cases where the virtual machine was very much slower than a physical one. It boils down to the following ruleset (with us) when not to virtualize: Network-io-intesive applications (i.e. with many interrupts/packets) Disk-io-intensive (if not on SAN storage) RAM-intensive (this is the most precious resource) Now this is true for a combination of XEN using local DRBD storage. The same seems to be true for Hyper-V using DAS. I wonder - is it true for all combinations - and what are your limits on these combinations?

• Can SysPrep (or anything else) be used to make a Win XP partition from another computer bootable?

  - by chris5gd

  I've used Paragon Backup and Recovery Free as recommended to me in my other question, to backup my C: (Win XP) and D: (installed apps) partitions. Before taking the rather scary step of breaking the RAID 0 array on which it's currently installed, and restoring to one of the individual drives, I'd quite like to test the restorability of the imaged partitions. I've restored them on to a spare disk in another computer, which of course won't boot from them in their current state. Is it possible to use SysPrep (or another tool) on the restored partitions, to make it bootable?

• Snapshots are disappearing from Time Machine. Why?

  - by AntonAL

  I have TimeMachine enabled for my external HDD. I'm triggering backups manually 2 times per week. I have noticed, that some snapshots, that i made, are gone. I noticed this behaviour several weeks later, but i had doubts. To make it sure, i've recorded screen video with listing snapshots in TimeMachine. After watching my screen recording today, I'm sure, that for Augusut i had 9 snapshots. Now, i have only 3 of them. What's happening ? I had no crash disk reports, errors etc

• Restoring raid 5 array after bios flash

  - by cogergo

  I have just flashed my BIOS and now my machine does not detect my raid5 array! It has three 2TB drives in it so that is a LOT of data that will be lost! I have NOT deleted the array and it does not offer me to reboot I'm using Nvidia MediaShield! and Windows 7. Any ideas guys? Thanks! Update: here is the GUI raid configuration. As you see it shows one disk in the array but for some reason not the other two! Click for image of raid configuration error

• Is there a limit of max. number of files in external hard drive folder?

  - by tfs

  I have a FAT32 external hard drive where I keep backups downloaded from webserver. I have a directory with 30 subdirectories. One of the subdirectories contains 21381 files and when I try to copy more files into this directory I get 0x80070052 error. However,it's possible to copy one more file in this directory (only one) if I make it's name shorter (8 characters instead of 22 as it's original name). How do I solve this problem? Now I can not synchronize external hard disk files with server files which is very important for me.

• Preparing a hyper-v VM image

  - by Anteru

  We have a Hyper-V Windows Server 2k3, and we're hosting multiple VMs on it. However, right now, we always start the VM creation right on the server, i.e. when preparing a new Ubuntu image, I just install it into a new VM and set it up and when I'm happy we store the disk image. I wonder if there is a way to prepare a hyper-v image locally on my desktop machine instead? I'm running Windows 7, and I would love to be able to set up a VM so that we can copy the image over to the server and be done with it. This is for linux images only, and we definitely need the hyperv network integration. Is there a recommended way how to prepare hyperv images without running a hyperv instance somewhere?

• What is and what is not replicated in a glassfish cluster with a mod_jk load balancer?

  - by Navigateur

  I have a Glassfish (3.1.2) cluster over 2 computers as nodes, with a mod_jk load balancer. Are servlet instance variables replicated perfectly? If not, how do I make sure it is? Are all actions, including method calls and disk writes, replicated perfectly? If not, how do I make sure they are? These may seem like stupid questions, but I'm not seeking "load balancing" as much as I am seeking exact replication to enable future upgrading without any service interruption. How do I achieve this if it is not already the case?

• Moving a File While It's In Use -- How Does it work?

  - by Zaz

  I've noticed that on non-windows OS.... ie linux/mac i can do things like: - Send a zip to a friend over aim - Delete the file while it's in transfer And the transfer does not fail. Or, I can do operations like.. - start a movie - erase the file - the movie still plays to completion (read from disk, not just buffered in memory) Although the files are being "deleted", as i mentioned, they are actually being moved to a different location on the file system... ie a Trash directory or something. So it seems to me like the OS uses a pointer @ the file that is updated when it moves rather than accessing the files directly. Can anyone shed some light on how this AWESOME capability is actually implemented? I'm not even sure what to google to learn more about it. thank you.

• process ksoftirqd consumes permanent 15% CPU load [closed]

  Possible Duplicate: Anyone else experiencing high rates of Linux server crashes during a leap second day? The process ksoftirqd/0 uses permanent 15% CPU on our debian squeeze server. 4 root 20 0 0 0 0 R 15.0 0.0 850:59.17 ksoftirqd/0 I already read that this can have various reason like Full harddisk or high network traffic. In our case we do have more or less low network traffic and enough space on hard disk. How can I analyse what causes ksoftirqd/0 to use permanently 15% CPU?

• Extract X11 configuration information from running instance.

  - by kasterma

  Since I had a hard disk die on me, I figured I could easily try some other OS (I usually run Ubuntu). Turns out that Ubuntu flawlessly recognizes my video card and monitor (X11 works right out of the box), and none of the other systems I tried gets anything working (I tried CentOS and FreeBSD). In my now working version of Ubuntu I cannot find a configuration file with information I could try to use with one of the other versions, which makes me guess that it just detects the hardware every time. Can I extract its choice for drivers and configuration options somehow (so I can try these same options in the other systems)?

• Moving to an SSD with Windows 7

  - by Nick Gerakines

  Disclaimer: I've been digging around for a few days and didn't get what I was looking for in terms of answers, so I'm asking here. I've recently purchased an 80g SSD drive to use as my boot up and OS parition. I've got a windows 7 desktop with two 1TB (raid0) disks currently and I'm not sure where to start in terms of copying / moving the OS. I suppose that doing a fresh install isn't out of the question, but I've got an upgrade disk from Vista that I'd have to deal with. Where do I begin?

• New Vaio laptop, performing a fresh install

  - by Slace

  I just purchased a new Sony Vaio laptop (z-series) but being a bit of a power user I really want to get rid of the software which is installed on it. I can go through the Programs and Features and manually select each item I want to get rid of, but it's a really tedious process. I'd much prefer to have a clean Windows install which I can then tweak from the get go. But it doesn't appear that I received a Windows 7 install disc (I bought it through a large reseller so it isn't dodgy as far as I know). I do have the Windows 7 licence key on my laptop underside, will this be valid if I use a Windows 7 install disc from work? Or should I have the Windows 7 disk and I need to go back to the reseller?

• Can files deleted on an ecnrypted drive be restored?

  - by roddik

  Hi. There are ways to restore files, deleted from the system by default, I'm not sure about the way they work but I guess thet read content, that has not been overwritten. On the other hand, there are programs (e.g. TrueCrypt), that encrypt disks, claiming that it wouldn't be possible to tell apart random data and file contents on such a disk without a password. Therefore I think that files, deleted from such disks can't be restored. Is that correct? I know one way to find out would be to try it, but there is a possibility, that I would just pick the wrong restoring software. Moreover, I'm more interested in theorethical explanation why it would/wouldn't be possible. Thanks

• trying to set up wireless router, failing

  - by j j

  Hi, I am trying to set up Netgear's wireless-n WNR2000 router, following their oversimplified 5- step process for plugging in wires, and I'm not having any success. It comes down to: once everything is wired and turned on in the correct order, all of the LEDs match the image they give of 'what should be lit up', but their setup disk still doesn't find the router. They have a site to set up the router manually, www.routerlogin.net, which I cannot navigate to, even while wired directly to the router. http://192.168.1.1 doesn't connect to anything, either. The interesting part: i get ping replies from Google's DNS server at 8.8.8.8 while this is set up. but cannot connect to any web site by name, since the router's DNS isn't set up. One thought is that the router and modem both have the same IP address, so it's conflicting, but I'm not sure how I'd resolve that. Any ideas?

• Sql database dumps failing every night

  - by chaseman36

  Hey guys, I have sql05 and my maintenance plan which backs up a database to an external storage SAN, has been failing every night. Here is my error: Executing the query "BACKUP DATABASE [master] TO DISK = N'\\192.168.x.x\vmbackup\server\dbbackup\master_backup_201004222300.bak' WITH NOFORMAT, NOINIT, NAME = N'master_backup_20100422230002', SKIP, REWIND, NOUNLOAD, STATS = 10 " failed with the following error: "Cannot open backup device '\\192.168.x.x\vmbackup\server\dbbackup\master_backup_201004222300.bak'. Operating system error 5(Access is denied.). BACKUP DATABASE is terminating abnormally.". Possible failure reasons: Problems with the query, "ResultSet" property not set correctly, parameters not set correctly, or connection not established correctly. I googled this error and tried adding permissions to the backup device for network service as recommended at experts exchange, no dice. Does anyone have any ideas?

• Does multi-platter hard-drive use all of their heads to read simultaneously?

  - by WiSaGaN

  Suppose we have a harddisk with 2 platters with characteristics below: Rotational rate: 10, 000 RPM Avg sectors/track: 1000 Surfaces: 4 Sector size: 512 bytes I was reading "Computer Systems: A Programmer's Perspective 2ed" when I found that it calculates transfer time as if it only uses ONE head to read a sector. If that's the case, why not use 4 heads to write(read) on 4 surfaces? So when I write a 2K bytes file, each head should only need to wait for the platters to rotate just one sector length instead of 4, thus reducing the transfer time by a factor of 4. Or even redesign sector to make each sector on one cylinder but on 4 tracks residing same position respectively on 4 surfaces. Each one of (512/4) bytes. So when the hd needs to read a sector of 512 bytes, we only need the disk to rotate roughly 1/4 compare to original time. The idea looks like RAID 0.

• Install Windows 8 (clean) on Hybrid Drive

  - by Ananthakrishnan Ravi

  I have a Sony Vaio T series (UEFI) that consists of a Hybrid Drive (SSD + HDD). I would like to install Windows 8 on the SSD and keep the Program files and other applications on the hard disk. What I could perceive was to keep the SSD as the System Drive. I'm able to install the OS on the SSD, but I run into some issues where I don't see the Microsoft Store App on my system and there are no apps on Windows 8. I tried using this blog post but doesn't seem to fit for Windows 8. Any help in this regard would be great. I would like the Windows 8 alone on the SSD, I don't care about the space wasted on the SSD and install other programs on my HDD. Thanks

• We want to setup low cost private cloud [closed]

  - by Virtual Jasper

  We are a small company with very limit funds. In order to improve our server reliability, we are studying to migrate to CLOUD. We seen some CLOUD provider, they would charge by resources such as, CPU, RAM.....Disk space....High Availability....etc. We have server team, so we also consider to built the private CLOUD, we seen the Windows 8 server, it does need license fee. So we looking at Linux side, we look at Ubuntu and OpenStack. What is the different between Ubuntu and OpenStack solutions? Is it both free on software license? and only to pay the technical support.
