  • Help slecting dedicated server with good disk I/O & network

    - by JP19
    Hi, I am looking for a cheap dedicated server. (I was earlier happy with VPS, untill I realized that the disk I/O is not at all reliable and depends on what your neighbours are upto at the moment). I was browsing through http://www.lowenddedi.net/the-database I don't understand memory speed and NIC speed columns at all. What will be their affect? Do I need to worry about them? Also, can someone help suggest a provider, with following criteria: 1) Good & reliable Network 2) Price <= $60/month. Thanks JP

  • Computer refuses to boot either ubuntu disk I'm using

    - by xtraorange
    I'm attempting to set up an Amahi server, and thus have taken an older PC and wiped it clean using DBAN. I'm now in the process of installing Ubuntu, but for some reason the computer refuses to recognize either form of Ubuntu I throw at it, even though it recognizes the Windows XP CD fine. Things it can't be: Boot order - I've tripple checked A bad DVD - I've booted the live CD off of my Mac just fine. A drive issue - the drive boots other cd's just fine, I've tested both an XP and the ultimate boot disk for windows... they are booting fine. A drive conflict - I have unplugged the only hard drive, leaving the DVD drive alone, still no recognition. I've tried both Ubuntu 12 and an older Ubuntu 10 CD, it refuses to recognize either one. It's like my computer has decided it will have nothing to do with Ubuntu. Any help would be greatly appreciated.

  • KVM guest disk performance

    - by Alex
    My KVM guest does max. 200MB/s although the host does easily 700MB/s (Raid 0 with 4 SSDs). Configuration: File-based storage (raw), cache none. Host 24 cores, 96GB ram, Ubuntu 12.04.1 LTS and virt-manager. I suspect the CPU to be the bottleneck (one core goes up during hdparm). Anyone experienced the same or has an explanation ? Edit: one more info: guest is the same as host (Ubuntu 12). Same poor disk performance observed with Windows 2008 R2 and Suse Enterprise Linux (9 or 10 I think). Max 1 guest running.

  • Preseed Ubuntu installation with full disk encryption

    - by user249264
    I am trying to set up Ubuntu full disk encryption using preseeding. I was able to set things up correctly following the preseed file presented here. But I do not want to provide the default password in the preseed file. Is there a way to let ubiquity fall to the screen that asks for the encryption passphrase just like it does when the username is not provided in the preseed file? When I try to leave the passphrase option empty in the preseed file, I get an error in the installer saying "An error occured while creating the keyfile".

  • How can I implement full disk encryption for a disk containing Ubuntu with plausible deniability?

    - by Rupert
    I would like to have a disk that: has Ubuntu installed is fully encrypted is setup in such a way as to make denial of the existence of the Ubuntu install plausible Truecrypt provides the last two features but only for Windows: http://www.truecrypt.org/docs/?s=sys-encryption-supported-os The alternate installer for Ubuntu provides the first two features but not the last. I imagine that plausible deniability would be achieved by, at least: Having two installs of Ubuntu and 2 passphrases (or keyfiles) which would unencrypt each one. Moving any unencrypted data (such as /boot) onto a USB stick Are there any programs out there which support this feature set for Ubuntu?

  • 3TB non-boot hard disk on older motherboard

    - by Bcos
    It is time to expand the capacity of my Ubuntu home file server so I would like to purchase some 3TB hard disks. However, I am concerned with potential compatibility issues. I've tried searching around but I haven't found information which clearly addresses my particular situation. My server is running Ubuntu 10.04 on an Intel P35 chipset based system. The motherboard does not support UEFI (and, by extension, GPT?). However, Ubuntu does support 2TB disks. Will I be able to properly utilize these new disks, or does the motherboard limitation trump all else? The boot disk is <2TB and will not be updated nor am I dual-booting; these disks will be used strictly as slaves in a pure Ubuntu environment. I'd hate to pull the trigger on these new disks just to be unpleasantly surprised, so any feedback is appreciated. Thanks!

  • Empty Disk when trying to install dual-boot system

    - by Lambda Dusk
    I recently purchased an SSD to speed up my computer experience. Before, I had Windows 7 and Ubuntu in a dual-boot system. The plan was to install Windows 8 on the SSD and then set aside ~30GB for the system files of Ubuntu. I installed Windows 8 just fine on the SSD, then I booted the Ubuntu install CD to make my partitions like always - but GParted tells me the entire SSD is unallocated. Now I am afraid I will lose my Windows installation if I try to do anything to it. Why does GParted think there is no partition on the SSD? Shouldn't it be 4 Partitions, like the Windows installer told me? And is it possible to ignore this and install Ubuntu on the hard disk (where it, frankly, already is) and somehow make it possible to install GRUB on the SSD to revert my dual-boot system without damaging the installed Win8?

  • Make recovery disk for customers

    - by alexander7567
    I hear about other computer shops that sells customers recovery disks that they have created. I'm assuming all that they do is make a image and uses an automation script that allows this to be done. I have seen where clonezilla does this, but it has to be the same HDD size or they might have problems down the road. Is there any other freeware that I could do this with that allows you to use on any size disk. Ghost is really good for this because it automatically fills up empty space with the partition and never needs any user input or "Expert Mode" like clonezilla. But it is not freeware.

  • How to create a bash script to check the SSH connection?

    - by chutsu
    I am in the process of creating a bash script that would log into the remote machines and create private and public keys. My problem is that the remote machines are not very reliable, and they are not always up. I need a bash script that would check if the SSH connection is up. Before actually creating the keys for future use.

  • How to check SERP position correctly?

    - by Cengiz Frostclaw
    I wonder how do you check your website's SERP position for a certain query. I cannot directly go to Google and search, because it knows i'm looking for my site, and it shows it in the first position, but from another browser, it cannot be even in the first page. So how do you check for "average user" ? I use Tor browser for that, since it gives me a completely different IP, do you think is it safe? I mean, does it give useful information ?

  • T-SQL Tuesday #016:Check Your Service Accounts with PowerShell

    - by AllenMWhite
    T-SQL Tuesday #016:Check Your Service Accounts with PowerShell This T-SQL Tuesday is about Aggregate Functions. It may be a bit of a stretch, but a security best practice to use separate service accounts for all your SQL Server services, so I've written some PowerShell code to check to see if any account is used more than once on a given machine. I take advantage of the SQLWmiManagement DLL to find the SQL Server services, which is a safer bet than filtering on a service name. First I load the SQLWmiManagement...(read more)

  • Force RAID to read "exiled" disk?

    - by user197015
    We have a RAID 6 array (Infortrend EonStor DS S16F) that recently had two disks fail. Immediately prior to replacing these two disks, a third, good, disk was accidentally ejected from the array. After reinserting this disk it is marked as "exiled" by the array's firmware, and so even after replacing the two failed disks with new ones the array refuses to rebuild the logical volume and remains inaccessible. Since the temporarily-ejected disk is still functional and nothing has been written to the array since it was ejected, it seems that it should theoretically be possible to recover all the data on the array, but how can we convince the array to use the data from the "exiled" disk? Thanks for any help or advice you can offer.

  • Spikes of 99% disk activity in Windows 8 Task Manager

    - by Jonathan Chan
    For some reason Windows 8's Task Manager reports spikes of 99% disk activity for hours at a time. Looking at the entries in that column, however, data doesn't seem to be getting written any more quickly than when the disk activity is around 25-50% (which it seem to idle at most of the time). Furthermore, when these 99% disk activity spikes are happening, the average response time reported in the Performance tab becomes 4000-6000ms. Is there a good way to find out what is causing the disk activity? I've tried using Process Explorer, but I said above, the rate at which data is reportedly being written doesn't seem to correspond (Dropbox and Google Chrome are constantly the top two, but the spikes are not dependent on their being open). Thanks in advance for any help. It gets very annoying when the computer stutters to a halt.

  • Time Machine (OSX) doesn't back up files in Mount Point or Disk Image File

    - by Chris
    I found this Q&A (http://superuser.com/questions/148849/backup-mounted-drive-of-an-image-in-time-machine) and this prompted me to ask the following question: I have two disk images which are scripted to be mounted on login. These two disk images are always mounted to the same location. These two disk images are encrypted TrueCrypt volumes. Time Machine (TM) will only back up the disk images the first time they are mounted, but not after that. As I modify documents within the volumes throughout the day, the modified timestamps are adjusted properly. However, TM does not back them up. TM never backs up the mount points which are two folders within my home directory. Any ideas as to why neither the mount point or the image files are backed up? Do the image files have to be closed (unmounted) after being modified for TM to back them up? Thanks, Chris

  • Disk I/O error copying a Exchange 2007 database

    - by Scottio
    Hi all, A short time ago due to disk space I moved our Exchange database onto an external drive, the drive was new and the database was being backed up daily. I've now discovered the database is corrupt, I've run the Exchange utils to fix the database and this works but it corrupts again as soon as I try to move it. I need to get it off the disk, any suggestions? I'm also trying to restore the last good database but I'd like try to get the database off this disk, any suggestions? PS I know putting the db on an external disk was a bad move, I had no where else to put it :-( Thanks

  • replace laptop hard disk

    - by 5YrsLaterDBA
    I have bought a ACER Aspire 5736Z-4790 laptop for my parents. It just passed the warranty. I think the hard disk is bad now. I cannot open/copy some of my files. It will crash (blue screen) when I do chkdsk /f/r in the stage 4 of 5 which is verifying file data. I can hear a strange noise when it is reading the bad sectors (I guess because it hangs there.) I am thinking replace the hard disk. should I buy the same hard disk or any SATA laptop hard disk will be ok? BTW, is there a way to repair it (with software)?

  • Can't activate dynamic disk

  • What is the data transfer speeds within the disk, to other devices?

    - by Kumar
    I use Debian 6 on a HP Elitbook 6930 with 2Gigs of RAM. I was copying two AVI files, 1.5 GB in total, and noticed that the data copying was done at the rate of 4MB/sec. When I copy same AVIs to my Western Digital Passport 25G USB plugin drive the data transfer speed is 11+MB/sec. This speed is different if I plugin the drive to different USB ports. Interestingly, at work I also downloaded a 16MB IE8 exe on my virtual xp, run inside Oracle Sun Virtual Box, and it was downloaded AND saved within a second. We have a high speed network at work. :-) Why and how this difference in data speeds is possible?

  • So I want to separate my Program Files from the hard disk with the other system files. What is the b

    - by grg-n-sox
    So I am running Windows 7 as my only OS. I have two hard drives on my computer. The first one is a 74GB Western Digital 10K RPM Raptor. The second one is a 1TB Seagate Barracuda (couldn't remember if it was a 7200.12 or some other decimal after the 7200). The OS in installed to the Raptor and I am just using the Barracuda for storage. With this setup, in case you couldn't guess already, the Raptor fills up quick and I am constantly having to maintain file locations. And although it is nice to have that quicker boot time and program loading, the time spent maintaining the drive makes me waste more time overall. So I am looking for a way to try to keep it clear while still keeping up system loading speeds. A performance hit on games and such is easily acceptable and as long as I can guarantee a 5GB space on the Raptor, I can always just temporarily move the disc image there. So I am figuring that having games installed like Boarderlands and Mass Effect, as well as having large files such as linux distro DVD disc images in My Documents, I probably should be moving my personal files and Program Files directories to the Barracuda. I currently have folders on the Barracuda for this, but this means routinely copying files over and I can't really do anything with the Program Files folder that already exists. The best I can do is remember to designate the install directory of any program installation to the alternative install directory, which I can't seem to get to ever work right with Steam. With that in mind, is there a way that is not too drastic to let me just change some folders and system settings once and everything works fine afterwards for my setup? I have considered just reinstalling Windows 7 to the Barracuda but that would defeat the purpose of the Raptor except for running disc images off of. I am also heard a bit about being able to use symlinks to fix this, but I have also heard that symlinks in Windows are not necessarily the same and not as well supported on Windows. An example a friend mentioned was something about how if you have a symlink in Windows on a small hard drive to a large hard drive and the contents the symlink points to is larger than the small hard drive's capacity, then Windows will think the smaller hard drive is full. So is there a fix/workaround that will let me use symlinks across hard drives without the issues or is there a better solution I am not being told about, not mentioning, or not thinking of?

  • Possible to restore Windows Partition disk image?

    - by kd7iwp
    I have a machine that was dual-booting Windows 7 and Ubuntu 12.04. I used the Disks program in Ubuntu to make a disk image of my windows partition which I saved on an external disk. I then reformatted the main drive and installed Ubuntu 12.10. I created a spare partition and restored that Windows disk image to that partition. Is it possible to boot Windows? I have run boot-repair and Grub now gives me both Ubuntu and Windows options but when I select Windows I get only a black screen with blinking cursor. I ran a Windows recovery disk and ran startup repair but still no luck. I also tried running lilo inside Ubuntu but still can't boot Windows. Any other ideas? PS, I'm on a Netbook with no DVD drive so I can't just reinstall Windows though if that is my only option I can borrow a DVD eventually.
