• Ubuntu 9.10 LiveCD stalls after "Install Ubuntu" selected from boot menu on eMachines

  - by nicorellius

  I am trying to install Ubuntu 9.10 from the ISO on a CD (it needs to be this version) on an eMachine with a brand new Seagate hard disk. The CD boots OK, and I choose the language. Then I am presented with the boot menu: Try Ubuntu Install Ubuntu etc I have tried the top two choices several times (trying Ubuntu and installing it), but each and every time the installation stalls and the disc stops spinning right after I hit enter after choosing the option I want. I have tried different CD/DVD drives, changing the jumpers on both CD drives, different hard drives, and nothing works. Maybe there is a BIOS setting that is choking the installation? Any help would be appreciated. Edit - I just tried running the hard drive as the master on the primary IDE and the CD drive as the slave on the primary with the same results. Maybe flash the BIOS?

• Home Server restore fails cannot find boot device

  - by Tim Heuer

  I am using Windows Home Server to backup my PCs. I recently had a hard drive failure on one of my WHS connected PCs and obtained an identical sized/speed drive for my laptop. I used the latest home server restore CD and did the restore. It said it completed successfully. Upon reboot, it says 'cannot find boot device' and lists all my drives (hard drive, cd, network book) indicating no valid operating system was found. I boot using the Win7 repair disk and while it doesn't see the operating system, it sees the drive and if I go into a command prompt, I can see all my data on the drive. My laptop is Windows 7 64-bit Ultimate. I've tried most everything I can think of. I'm a technical user (software developer) so I'm pretty aware of how things work (or should). I don't feel like I'm missing a simple step here.

• Is it possible to save the product key of Windows 8?

  - by Dibya Ranjan

  I have Windows 8 activated in my system. I don't have the product key of windows right now. Now I want to format my system again. Is there any way so that I can reuse the key? Is there any way I can get the key from an activated windows machine? Edit: I am not able to find the product key because I have used a MAK as my product key. Now I want the same to use it after formatting my disk. I found a software Volume Activation Manager tool on the windows website. I am not sure how to use it. Please tell me how can I reuse my key?

• Is vSphere's Data Recover appliance 'production-ready'?

  - by Chopper3

  I have a smallish lab environment (16 x ESX4iU1 hosts and VC4U1) that I periodically want to backup. Normally in production we snap to secondary SAN boxes then have disk-based VTL backups via NetBackup which eventually migrate to off-site removable disks but this seems like an overkill for my own kit. I've spent a bit of time with vSphere's 'Data Recovery' appliance, it was easy enough to setup and I've not really ran into any issues with it but that doesn't mean I trust it fully. Have you had any experiences with it, positive or negative that would help me decide whether to trust it or pay Symantec for more licences? Thank you in advance.

• How to netboot ubuntu running iniside VirtualBox on Mac Air

  - by murungu

  Having configured a virtual machine for Ubuntu on VirtualBox on my mac air I need to install Ubuntu OS itself. I have selected the hardrive as the primary boot device and the network as the secondary boot device, so I am not prompted to install an Ubuntu disk at boot time. It attempts to netboot but is unable to locate Ubuntu and cannot find anywhere in the configuration where I can explicitly specify where to find and Ubuntu image, so assume it reverts to some default location and fails. Has anybody out there ever successfully installed ubuntu on virtual box on their Mac Air? What steos did you take to get it right?

• Same SCSI drive appears multiple times on the controller list

  - by ohad

  Hi, I have an Adaptec AHA-2940UW SCSI adapter, to which I connected a single Atlas 10K III drive (and nothing more). When my computer loads up, the pre-OS Adaptec screen shows (I believe this is called the POST screen), where I can see the Atlas drive listed many times (i.e. with ID0, ID1, ... ID5, ID7, ID8,...,ID15 [ID6 is the adapter itself]) Using the same HD on an Adaptec AHA-2940UB the disk only shows once Since my OS hasn't been installed yet, I'm not sure if this is a problem (I would guess it is), and if so - how to solve it. Termination and multiple LUNs come mind, but the cable provides termination and I don't see why a hard drive would request multiple LUNs, especially considering it is not jumpered at all, and multuple LUN support is disabled in the Adaptec controller BIOS (via the SCSISelect utility) Thank you

• Delta files not deleted

  - by DanieleF

  Dear al, I found out that my VM is running with a snapshot which is not visible in the snapshot manager. I found out also that the machine is running on a delta file (probably an old snaphot) I see there are procedures to consolidate snapshots but what i want to understand now is : Having a VMDK-flat disk of 50gb =which is actually the vdisk created at the beginning Now i have a DELTA file of 38 gb...and this file it is growing on daily basis. My question is : why the delta file is growing ? is that normal ? Please let me know what is behind.

• Allow WRITE access to local folders machine in 2003SBS AD

  - by Dan M.

  Have a SBS2003 client with a mess of a domain that is in process of being cleaned. But, for the life of me I cannot find a setting that will allow write access to the local hard disk for domain users with redirected profiles(to the server). This is needed only for one program that will not follow a symbolic link to the network path, instead it seems to be hard coded to the %appdata% folder but only on the c: drive.... So question is how can I allow "Domain users" write access to the local %appdata% directory? I have tried setting it manually on a machine but it kept resetting to RO no matter how many times I tried. Every time I would un-check the RO property it would reset sometime right after i hit OK. Thanks in advance! Dan

• Switching to Linux, Need backup help

  - by Stephen

  I have an existing Vista installation on my thinkpad x200 and I want to install Linux on my machine. I've done this several times already but I usually format the whole disk and dual boot on Windows and Linux. Which means I have to reinstall and reconfigure everything I had on Windows. What I want to do is backup my windows installation (into an image) and start a clean Linux installation, and run the windows image thru Vmware or Virtualbox. Whats the easiest way to do this? any free tools available? I've seen acronis but dont wanna buy it for a 1 time session only.

• Graphing services using pnp4nagios

  - by Matias

  I've managed to install pnp4nagios 0.6.3 and I'm a bit confused about how pnp4nagios generates graphics. Almost out of the box, it started graphs for ping and some http servers (not all of them). But, how can I make it graph things like disk utilization (When that value comes from SNMP)?? For example, ls /usr/local/pnp4nagios/var/perfdata/isis/ Cola_de_Mail.rrd Cola_de_Mail.xml HTTP.rrd HTTP.xml PING.rrd PING.xml Those are checks running on the host isis, but there are many other checks for that server that are not taken into account by pnp4nagios. How can I make pnp4nagios "see" the other checks?? Thanks!

• Thoughts on Apache log file sizes?

  - by Nathan Long

  Do you place any limits on the size of Apache log files - access.log and error.log? Specifically, can you give: Reasons to limit log file sizes Disk space Any other? Reasons NOT to limit log file sizes Research into performance issues or security breaches Any other? Methods of doing so Cron job that periodically deletes the file, or the first N lines? Any other? Anything you might salvage before deleting For example, grep out how many times a file was downloaded before deleting the access logs I'd like get the thoughts of experienced sysadmins before I do anything. (Marking as community wiki since this may be a matter of opinion.)

• PC won't boot / USB and PS2 keyboards don't work

  - by Truncheon

  My brother's PC has stopped working. He now cannot boot into windows, and he can't access BIOS by pressing the DEL key as no keyboards work. He has tried 4 different keyboards, one of which is PS/2. He tried the USB keyboards on all the USB ports. I don't know why the BIOS would show the message "Floppy disks fail (40)", as there is no floppy disk drive in the PC. He has upgraded from XP to Vista (yes that's right, upgraded keeping the XP drivers, eyes roll). A BSOD occurred in Vista while he was browsing files. What steps should be taken to troubleshoot the problem?

• How do I make my Boot Camp partition bootable again?

  - by Dan Herbert

  I needed to resize my Boot Camp partition so I used Gparted to move and resize it. This seemed to work, except that now I can't boot into Windows. I can boot into OS X just fine. OS X can recognize the Boot Camp partition and view its contents. When I try to reboot into Windows, however I get the message: No bootable device -- insert boot disk and press any key The only solutions I've been able to find online suggest that the only way to fix this is to either clone the drive or remove the Windows partition and re-install it. Is there any way to fix my Windows partition so that I don't have to reinstall Windows again?

• Outlook items suddenly disapears from inbox after synchronization

  - by Jan Šotola

  We had some disk problems on Exchange server. We had to fix the Exchange 2007 using eseutil. Everything works fine excpet of following problem with one e-mail account: All inbox messages of mentioned e-mail account are fully accessible through the OWA. When any user creates new Outlook profile (using .OST mode) and starts synchronizing, all inbox messages are visible in the Outlook's inbox folder untill the Inbox synchronizing is completed. Once the synchronizing progress bar reaches 100% (and the Outlook starts synchronizing Sent items or another folder), most of messages disappears from the inbox view of the Outlook. The .OST file size does not reduce. New mails (delivered after Exchange server crash) remains all in the inbox. There is no special view or filter applied in the Outlook. The problem has been reproduced on two different computers (Vista+Office2007, Win7+Office2010). We assume there is some problem on the Exchange server but we don't know how to fix it. Can anybody give us some advice?

• What hardware makes a good MongoDB Server ? Where to get it ?

  - by João Pinto Jerónimo

  Suppose you're on dell.com right now and you're buying a server to run your MongoDB database for your small startup. You will have to handle literally tens of thousands of writes and reads per minute (but small objects). Would you go for 2 processors ? Invest more on RAM ? I've heard (correct me if I'm wrong) MongoDB handles the most it can on the RAM and then flushes everything to the disk, in that case I should invest on a CPU with a large L2 cache, probably 40GB of RAM and a solid state drive.. right ? Would I be better off with a high end (~$11,309, 2 expensive processors, 96GB of RAM) server or 2x(~$6,419, 2 expensive processors, 12GB of RAM) servers ? Is Dell ok or do you have better sugestions ? (I'm outside the US, on Portugal)

• Jungledisk - choosing between Amazon S3 and Rackspace ?

  - by Dietmar

  Hi, jungledisk is owned by rackspace and offers an option to choose Amazon S3 which charges for traffic whereby if data is stored on rackspace, no charges for traffic. For a small company, to just backup files with jungle disk from ubuntu linux OS computers, i wonder what to choose. Commercial psychologically the price on traffic and the Amazon brand make it appear or maybe it is, of better quality than the cheaper Rackspace offer which is when it comes for just backing up ok ? but if its about backing up around 30 GB which updates from time to time, what would you consider a good choice ?

• ISCSI: Ethernet cable maximum length vs. SCSI command timeout

  - by Jeremy Hajek

  I have a question about a non-optimal setup and the practical implications of this. Ideally you would place the ESXi server right in the same room as the FreeNas white box end of question. My situation is this: I have a run of ~125ft of Cat 5e connecting a ESXi server to a FreeNas whitebox in the server room. I know the distance of the ethernet cable is within the maximum distance for ethernet traffic but I have two questions... Can Cat 5e support gigbit speeds at that distance if the switch on the back end is a linksys SRW-2048? Should I be concerned about the distance causing data read and write timeouts in the SCSI portion--(disk operations of the ESXi)?

• Viewing and deleting partitions using the BIOS?

  - by cluelesscoder

  I have an M4A785TD-M EVO Asus motherboard which uses Asus Express Gate for its motherboard (says American Megatrends, Inc at the bottom). I activate it by pressing Del; also says Tab activates BIOS Post but that doesn't seem to do anything. I went into this expecting to see a breakdown of the partitions. I have a 300GB hard-drive separated into 3 partitions. While it does show SATA for my main hard-drive and my disk drive, it doesn't show the partitions. Is this typical? Do I have to us an OS-based tool to delete the partitions or can I delete using my BIOS? I tried updating the BIOS through Asus's Update utility but it appears to be broken (connects/disconnects repeatedly). I used HWiNFO32 to get some information: BIOS Date: 06/30/10 BIOS Version: 2103 EFI BIOS: Not Capable Tried to update but it directs me to biosagentsplus.com which wants $30 for the download (another question would be how to avoid them).

• Software that supports ATA Secure Erase Command

  - by vy32

  We have a lot of drives that need to be sanitized. NIST SP 800-88 recommends software that uses the ATA Secure Erase command. That's apparently the only way to be sure that the drive is properly wiped, due to bad-block remapping and such. I know that this functionality is available in hdparm. The problem with that approach is that it is inconsistent on multiple platforms, occasionally times out, doesn't have error-checking logic, and doesn't check the resulting drive to make sure that it has, in fact, been erased. So a proper program might use hdparm, but hdparm by itself isn't an answer. I'm looking for open source software that implements ATA Secure Erase. Ideally it will be a bootable disk image like DBAN, but it will use the ATA command.

• Calculating IOPS for a single HDD - what am I doing wrong?

  - by red888

  So I know there is no standardized way of calculating IOPS for a HDD, but from everything I have read it appears one of the most accurate formulas is the following: IOP/ms = + {rotational latency} + ({block size} / {data transfer rate}) Which is IOs per millisecond or what the book I've been reading calls "Disk Service Time". Also rotational latency is calculated as half of one rotation in milliseconds. This was taken from the EMC book "Information Storage and Management" -arguably a pretty reliable source right\wrong? Putting this formula into practice consider this Seagate data sheet. I am going to calculate IOPS for the ST3000DM001 model for a block size of 4kb: Seek Average (Write) = 9.5 -I'll measuring IOPS for writes Spindle speed = 7200rpm Average Data Rate = 156MB/s So my variables are: Seek Time = 9.5ms Rotational latency = (.5 / (7200rpm / 60)) = 0.004s = 4ms Data Rate = 156MB/s = (0.156MB/ms / 0.004MB) = 39 9.5ms + 4ms + 39 = IO/ms 52.5 1 / (52.5 * 0.001) = 19 IOPS 19 IOPS for this drive clearly is not right so what am I doing wrong?

• How can I format a USB drive as FAT from a MacBook Pro?

  - by Edward Tanguay

  I plugged in a 250GB USB hard drive into my MacBook Pro and want to format it in FAT so I can transfer files back and forth between a windows machine. (My windows7 machine only formats in exFAT which my Snow Leopard 2.6.4 doesn't support until I do the update). So I want to format it on the mac. but when I right click on the drive, it gives me the options to eject, copy, but not to format. I can go into Disk Utilities, click on Partition, but the only option is the "Mac Journaled format". How can I Format my USB drive as FAT from my MacBook Pro?

• Network backup for Macs and PCs - formatting question

  - by neilfein

  I'm trying to use a LaCie 2TB drive as an AirPort drive, for backup on a home network. We have one mac and two PC laptops. My plan is to create a Mac partition and a Windows partition. However, Disk Utility won't let me set the windows partition to Windows format; there's no option in the menu for it in the partition tab. Am I doing something wrong? Alternatively, is there a way to partition the drive with one partition that all three machines can see? We have a Mac G5 with 10.4 and two laptops with Windows 7. Thanks!

• Method for imaging a HDD? [closed]

  - by Sonny Ordell

  Possible Duplicate: Imaging new hard drive in Windows 7 laptop? I have to image my 320gb Laptop HDD before I send it in for repairs. The HDD is likely going to get replaced, and I would ideally like to be able to restore everything as I have it now without having to reinstall my OSes, programs and place all my files back again. I can make space on an external HDD I have, so am just looking for how I should go about this. Should I just use dd with a linux rescue cd? Or is there perhaps a more suitable program with its own rescue disk?

• High level command line program for burning CDs and DVDs?

  - by stickmangumby

  I'm sick of screwing around trying to script a clean solution to burn multiple files and folders to CDs and DVDs with wodim, growisofs and genisoimage. I'm looking for a high level command line program that uses sensible defaults and takes arguments something like this: [program-name] [cd|dvd] /path/to/dir1/ /path/to/dir2/ /path/to/file ... It should then do all the low level copying and ISO generation transparently and just burn the damn disk! Does anyone have any suggestions? I've looked at several programs but it seems there are too many choices to trawl through and not enough information about them online. Thanks :)
