• Windows 2008R2 two node failover cluster creation fails

  - by Francois Wolmarans

  We have just installed two Windows 2008R2 Enterprise machines with identical hardware. When running the cluster validation everything is ok. When creating the cluster it fails with the following error: An error occurred while creating the cluster. An error occurred creating cluster 'CLUSTER04'. The parameter is incorrect The logfile on the first node where we are running our config from, does not show any errors. On the second node we get: The Cluster service is shutting down because quorum was lost. This could be due to the loss of network connectivity between some or all nodes in the cluster, or a failover of the witness disk. I've double checked and all communication between the servers are fine. Even when creating a one node cluster it gives the error. There are other failover clusters we have setup without any issues.

• Why won't the floppy mount?

  - by dboarman-FissureStudios

  The 1.44Meg floppy won't mount in my Nautilus file browser. When I try to mount it, it says there is no media in the drive. Yet, I can write to the floppy through the terminal using the 'cp' command. I can enter the command: mount -t ext2 /floppy and it mounts. I have also run a check and the disk itself is 100% clean. So, why can't I get the nautilus browser to open up the floppy? Is there a way to see the actual floppy from the terminal?

• How to backup blog running on posterous.com

  - by Martin Vobr

  I'd like to backup content of my blog which is powered by posterous.com. I'd like to save all texts and images to the local disk. Ability to browse it offline is a plus. What I've already tried: wget wget -mk http://myblogurl It downloads the first page with list of posts, then stops with "20 redirections exceeded" message. WinHttpTrack It downloads the first page with redirection to the www.posterous.com home page instead of real page content. Edit: The url of the site I'm trying to backup is blog.safabyte.net

• Missing graphics accelerator for Toshiba C855D-s5232

  - by user2387429

  I formatted the drive and re-installed Windows 7 64-bit on a Toshiba Satellite C855D-S5232. Now I am missing the graphics accelerator. I have been to Toshiba's website but cannot find the right one. Same is so for AMD. It has AMD E1-1200 APU with Radeon HD Graphics. The machine is recognizing a standard VGA. I ordered a recovery disk on eBay and it was supposed to be here yesterday. Can anyone help with other options?

• Mac Book Refuses to Boot

  - by pas09

  I have a Macbook that has unfortunately died on me. I randomly got a pop up message that said I needed to restart my computer, and once I did, I was greeted with the blinking folder question mark start up screen. I've tried everything, including running Disk Utility repair and reformatting the hard drive and reinstalling OS X. All of my data is backed up and safe, I just need my computer to start again. Before I go off and buy a new hard drive, I wanted to see if there is anything I might have forgotten.

• Windows 7 backup to 3TB Seagate external drive got 0x8078002A error [migrated]

  - by Zhang18

  I'm using the Windows 7 backup and restore utility to create a system image and personal file backup to an external Seagate GoFlex 3TB disk. I got the following error: One of the backup files could not be created. Details: The request could not be performed because of an I/O device error. Error code: 0x8078002A I searched all over the internet and found these two related discussions (discussion 1 and discussion 2). Note the 1st discussion is for a Western Digital drive, which seem to have a solution with the WD Quick Formatter tool. But I downloaded that software and it cannot detect my Seagate drive. The 2nd discussion is directly relevant but it does not offer a solution. I've spent days on this and am at a loss... Please help if you know what to do to make it work! Thank you!

• How tot track which program causes my harddrive to spin up

  - by Andreas

  I have a strange problem: Every half hour one of my hard disks gets powered on again. I recognize this by the sound of a hard disk spinning up. So far I was not able to track which program could cause this. I ran Process Monitor to see whether there is an I/O peak coinciding with the spin-up. I checked Windows event viewer if there is an appropriate event at the same time Any ideas other than the usual disabling-services/programs etc. (which would be my next investigation step)? Also, it would be helpful to have a program that shows the current power status of all my drives, if there is one. Harddisk Sentinel unfortunately cannot do the job because it powers on all drives upon start and prevents their going into sleep mode. Thanks in advance. :)

• Under kvm, Vista guest OS install halts on black screen

  - by Isaac Sutherland

  I am using kvm on my ubuntu-server-10.04 amd64 dual core PC. I am trying to install a Windows Vista guest OS. The installation proceeds properly until the system reboot halfway into the installation process, at which point it stops on a black screen and CPU usage goes to near zero. I created the vm with virt-install as follows: virt-install -n vista --connect qemu:///system -r 1024 -vcpus 2 \ --os-type windows --os-variant vista \ --virt-type kvm --accelerate \ -c /dev/sr0 \ --disk path=/dev/main/vista-hd \ --network bridge=br0 \ --vnc --noautoconsole Where /dev/sr0 is the physical drive with the vista installation DVD, and /dev/main/vista-hd is a 20-GB lvm logical volume I created. A number of people seem to have had success installing vista under KVM, but I haven't been able to determine what is causing my problem. Ideas anyone?

• OSX Reset Home Permissions and ACLs - how long should it take?

  - by andyface

  Having screwwed up my permissions by trying to have two users accessing one home folder I'm now going through the process of reseting my main user home permissions via the OSX install disk utilities, which seems to be taking a while. Does this process take a while to do, though I assume it depends on how many files I have in the folder, which in my case is a good few 100 GBs. At what point should I be concerned that it may have got stuck and thus reset my computer and try again? I assume, though not sure that if the little circle indicator is still moving then it's not completely frozen, but as there's no progress bar or details I'm not sure how true that is.

• Can I trust that ZFS is consistent between Linux and FreeBSD?

  - by iconoclast

  I'm planning to build a FreeNAS box sometime soon, but if ZFS on Linux eventually proves to be reliable, I might want to switch, just to have a more familiar OS. So I'm wondering if I can trust that the different implementations of ZFS are compatible. In other words, if I just swap out the boot disk from FreeNAS to Linux or OpenIndiana, can I trust that nothing bad will happen to my data? This may seem like a stupid question--obviously it ought to be compatible--but I'm guessing that ZFS isn't commonly used in cases where drives are moved between computers, so I'm hoping someone can provide a better answer than just "it ought to be".

• Securely wiping a file on a tmpfs

  - by Nanzikambe

  I have a script that decrypts some data to a tmpfs, the directory is secure (permissions), the machine's swap is encrypted (random key on boot) and when the script is done it does a 35 pass wipe (Peter Gutmann) of the cleartext on the tmpfs . I do this because I'm aware wiping files on a journaling file system is insecure, data may be recovered. For discussion, here're the relevant bits extracted: # make the tmpfs mkdir /mnt/tmpfs chmod 0700 /mnt/tmpfs mount -t tmpfs -o size=1M tmpfs /mnt/tmpfs cd /mnt/tmpfs # decrypt the data gpg -o - <crypted_input_file> | \ tar -xjpf - # do processing stuff # wipe contents find . -type f -exec bcwipe -I {} ';' # nuke the tmpfs cd .. umount -f /mnt/tmpfs rm -fR /mnt/tmpfs So, my question, assuming for the moment that nobody is able to read the cleartext in the tmpfs while it exists (I use umask to set cleartext to 0600), is there any way any trace of the cleartext could remain either in memory or on disk after the snippet above completes?

• Alternative to SecondCopy?

  - by overtherainbow

  Hello I've been using SecondCopy (7.0.0.146) on XP for a few years now to copy important files from one hard-disk to another. One thing that bothers me is that it is unable to copy some files that are open. I assume Windows provides an API that allows an application to put an exclusive lock on an open file and backup utilities like SecondCopy just can't access them until they are closed. As a result, since I have to close a bunch of files/applications for SecondCopy to complete successfully, I typically don't run SecondCopy regularly like I should... which pretty much beats the whole purpose of backing up data :-/ For those of you using a similar solution to back up your important file onto a second mass storage solution... Can you confirm that an open file can be set off-limit with an exclusive lock, and no backup solution will work with those? If you've tried SecondCopy and other solutions recently and you ended up using another solution, which one did you choose and why? Thank you for any feedback.

• Won`'t read Unicode characters over NFS mount ?

  - by Julz

  Hello, I'm getting this strange issue when trying to play mp3's containing unicode characters ( accents ) over an NFS on OSX, it's all good over AFP, but I'm setup with NFS because it's a linux server on the other end . This is my disk utility setup : nfs://192.168.1.112/Music advanced mount parameters : -P , nolocks nosuid The strange thing is that I can see those files in the finder ( with the accents .. ) but I cant play them !! So Im wondering if it's an unicode issue, since I can see the files properly or a permission issue since I can't play them, but them it wouldn`t make sense that I can't play ONLY the files containing accents .. help ?? Thanks

• Best Practices: How can admin deploy software to 100s of PC ?

  - by Gopal

  Hi ... The Environment: I am working for a college. We have a couple of labs (about 100 PCs) for students. At the end of the semester, the PCs will be full of viruses, corrupt system files, all sorts of illegal downloads etc. (everything you can expect from a student environment). At the end of the semester, we would like to wipe out all the systems and do a clean install (WindowsXP + a set of application suites) to get ready for the next batch of students. Question: Is there any free software that will enable an admin to deploy a clean disk image to all the PCs in one go?

• Windows 7 System process reading/writing like crazy

  - by Mats Ekberg

  I have a problem that my windows 7 computer sometimes starts accessing the disk like crazy for maybe 10 minutes at a time. The process in question is the "system" process. I have disabled superfetch and hibernation on my computer, if that makes any difference. I disabled those to see if they were the cause of the problems, but no change. I have 6 GB of RAM and only the web browser was started when I took the screenshot, so I don't think it was thrashing due to page faults. Any ideas on how to find the cause of this?

• Driverpack Solution makes a whole bunch of programs

  - by Markasoftware

  I am using Driver Pack solution 12.3 to update my drivers. I used it and installed 55 drivers. I noticed that there are now several dozen new entries in add/remove programs under the name Windows Driver Package - Intel hdc, Windows Driver Package - Intel System, and Windows Driver Package - Intel USB with the driverpack solution logo next to them. When I hit uninstall for any of these, it says all devices using this driver will be removed, and I am scared of uninstalling anything I do not know about. I have no system restore points before I updated my driver. Will these extra driver packages slow down my computer or take up extra disk space? Can I uninstall them safely? I am using Windows 8, so refreshing the computer is an option.

• Disable user_deny.db in Cyrus/imapd

  - by netmano

  We have a cyrus 2.4.12 on Debian, we use packages, rather than building each software ourselves. I am getting the this "log" constantly, a lot of, various users, and 8-10 times per user request: fetching user_deny.db entry for 'user123' I have searched for it, but haven't found a real solution, there were some patches for 2.3.xx, but we don't want ot build it, we prefer to use packages. Is there any solution to disable the user_deny.db at all. We don't need this feature. It wastes the CPU as disk.

• Mac Mini 1.66 no sound on Windows 7

  - by Steph

  I've tried everything I could to get the sound working. I've tried to install the drivers from the Snow Leopard disk, then I went and got the latest RealTek drivers from the RealTek website. Then I read that old Mac mini's could have an integrated Cirrus chip, and I tried to grab the latest driver from the website, and it appeared to install, but nothing. There's also nothing listed under Sound and ... in the Device Manager. I've tried to manually include a legacy driver, which worked for RealTek but not for the Cirrus driver. Of course it said there was no RealTek hardware install, which makes me think it's a Cirrus chip. Any further suggestions or thoughts would be really appreciated. This is a Mac Mini 1.66. I'm also not sure how to be able to detect what card is integrated into the system, so that would be helpful too (remembering that there's no driver installed). Even just to get the chip type would be great to confirm.

• Graphing services using pnp4nagios

  - by Matias

  Hi! 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!

• SQL Server 2005 Default Backup Plan

  - by tylerl

  I noticed that a newly imported database on SQLServer 2005 had configured itself (without my knowledge) to perform daily backups; but it's not deleting old files and quickly filling up the disk. I don't know how the backup job got configured (maybe that's something that gets transferred when you move a database?) but I'm having trouble modifying it. The backup runs as part of SQL Server Agent job called "Daily Backups". This job runs a package called "(SSIS Packages)\Maintenance Plans\Backup Plan" -- which I can't find. The "Management\Maintenance Plans" area for my server is empty. I imagine I could delete the existing plan and re-create it manually, but I was hoping to just modify what was already there, since all that's missing is deleting old files.

• Computer bluescreen-ing with 0x7A and 0xF4 errors

  - by lcarpenter

  Hiya, This computer is locking up for around 5-30 seconds before throwing Blue Screen of Death's with 0x7A and occasionally 0xF4 errors. The log files don't really show anything informative, and Windows Update doesn't show any new drivers for the HDD. Upon restart, it shows a "A disk error has occurred /n Press Ctrl+Alt+Del to continue", and to fix this I go into WinRE via the pendrive and run "bootsect /nt60 C: /force /mbr" and that seems to fix it so it boots. And then the cycle repeats. If you want any more information please ask. Thanks, Luke Carpenter

• Building optimal custom machine for Sql Server

  - by Chad Grant

  Getting the hardware in the mail any day. Hardware related to my question: x10 15.5k RPM SAS Segate Cheetah's x2 Adaptec 5405 PCIe Raid cards Motherboard has integrated SAS raid. Was thinking I would build 2 RAID 10 arrays one for data and one for logs The remaining 2 drives a RAID 0 for TempDB Will probably throw in a drive for OS. Does putting the Sql Server application / exe's on a raid make a difference and is there any impact of leaving the OS on a relatively slow disk compared to the raid arrays? I have 5/6 DBs combined < 50 gigs. With a relatively good / constant load. Estimating 60-7% reads vs writes. Planning on using log shipping as well if that matters. Any advice or suggestions?

• Defragment / Performance Monitor without Task Scheduler

  - by mjaggard

  My organisation has a policy of disabling Task Scheduler on all servers and workstations (don't ask, I tried once to wrestle the pig). I need to collect performance stats using Data Collector Sets in Windows 7 or Windows 2008 but the Performance Monitor interface requires Task Scheduler to be running. Is this possible because I'm not trying to schedule anything (except the collection of WMI information every 15 seconds but I doubt it hands that task off to the task scheduler)? Is there any way to trick it into thinking Task Scheduler is running? If not, is there any way to temporarily override the group policy to allow Task Scheduler to run? I've found that most group policy can be overridden in this way by an Administrator by editing the registry. On exactly the same vein, I want to defragment a hard disk on one of my workstations, but I can't get it to start because of the dependancy on Task Scheduler - is it possible to overcome this?

• ML 350 additional SATA RAID controller (mirror only)

  - by Nicholas

  I have a Proliant ML350 G8 with two SAS raid arrays currently set up - thereby maxing the default P420i raid controller. I need to set up a large video dump space in addition to this existing set-up (for non backed up, non-critical, temporary storage). I had planned to just add a 2TB SATA disk and plug it into the motherboard. However I it occurred to me the motherboard might have built-in mirror RAID support? Therefore I could use two SATA disks and have some semblance of redundancy. Is this possible? Or would I need to get a cheap raid card? Any recommendations?
