• What's the best way to be able to reimage windows computers?

  - by mos

  I've got a low-end machine for testing our software. It needs to be tested under various versions of Windows, so I was planning installing each one on its own partition. Then I realized that after testing our software, I'd want to roll back to the previous, clean state. I don't want to use any virtualization software because it tends to interfere with the workings of our app. That said, what's the best way to achieve my goal? Norton Ghost? Edit: I work for a pretty monstrously huge organization. Money is no object here (and sometimes, if the wrong people get wind of it, "open source" software is bad).

• How to verify /boot partition on encrypted LVM setup

  - by ml43

  Isn't unencrypted /boot partition a weakness for encrypted LVM setup? Attacker may install a malware to /boot partition so that it may sniff encryption password next time system boots. It may also be done by a malware installed to Windows on dual-boot system without any physical access. Am I missing some protection scheme or at least I may verify that /boot contents didn't change since last system shutdown?

• Very small image for rebuilds

  - by Deon

  I worked at a place last year that had a very small image for Windows XP re-builds. It was two Norton GHO files, totalling about 2-3 GB. This is how it worked: Boot into Norton Ghost Map to the network share where the images lived Apply the image to the workstation Reboot It would then load into Windows Setup Enter the Domain Admin credentials so it can join the domain That's it... it would then reboot into Windows and the image was complete. How did they make an image so small? Did they perhaps kick off a Windows install and create an image then? I particularly liked how it required no user input other than a domain admin login.

• Storage sizing for virtual machines

  - by njo

  I am currently doing research to determine the consolidation ratio my company could expect should we start using a virtualization platform. I find myself continually running into a dead end when researching how to translate observed performance (weeks of perfmon data) to hdd array requirements for a virtualization server. I am familiar with the concept of IOPs, but they seem to be an overly simplistic measurement that fails to take into account cache, write combining, etc. Is there a seminal work on storage array performance analysis that I'm missing? This seems like an area where hearsay and 'black magic' have taken over for cold, hard fact.

• Setting Boot and Mirror Disks correctly at the Solaris OBP

  - by Shaun Dewberry

  I am recovering a domain that was lost due to power outage on an Sun Fire E25K server. I know how to set the appropriate parameters at the openboot prompt using nvalias/devalias, boot etc. However, I do not understand how one gets from the output of show-disks {1a0} ok show-disks a) /pci@1dd,600000/SUNW,qlc@1/fp@0,0/disk b) /pci@1dd,700000/SUNW,qlc@1/fp@0,0/disk c) /pci@1dc,700000/pci@1/pci@1/scsi@2,1/disk d) /pci@1dc,700000/pci@1/pci@1/scsi@2/disk e) /pci@1bd,600000/SUNW,qlc@1/fp@0,0/disk f) /pci@1bd,700000/SUNW,qlc@1/fp@0,0/disk g) /pci@1bc,700000/pci@1/pci@1/scsi@2,1/disk h) /pci@1bc,700000/pci@1/pci@1/scsi@2/disk q) NO SELECTION Enter Selection, q to quit: to the correct full disk path. I know it is basically one of the pci/scsi paths listed above, but in all instruction or examples a string of additional characters is appended to the path to specify Targets and Units but the explanation of the path construction is never given. Could someone please explain how to construct this disk path correctly?

• Get extra hard drive space from windows 7

  - by abhinole

  I am using Ubuntu 12.04 and Windows 7 (dual-boot) on my laptop.For some reasons I want some more space in my Ubuntu partition.I have installed gParted in Ubuntu.Now is it recommended to get this required extra space from Windows 7 drive (*where my linux is installed *) directly using gParted? Will it cause damage to my boot loader or my data on the partition from where I wish to grab some space? Any help will be appreciated. Thanks in advance.

• How can I boot a vm on Hyper-V 2012 when it has a virtual hard-drive missing?

  - by Zone12

  We have a Hyper-V 2012 server with 8 VM's on. We have attached extra virtual hard-drives to each of the computers to store backups on. These drives are stored on a NAS. After a power failure, we tried to boot the VM's and found that they couldn't be booted without the attached backup drives. We couldn't boot the NAS at that point and so we had to remove all the extra drives manually, boot the VM's and re-attach the drives at a later date when we got the NAS back up and running. These backup drives are non-essential to the running of the system. I would like to know if there is a way to boot a VM on Hyper-V 2012 with some of the hard-drives (scsi) missing so that we can recover automatically from a power failure.

• San Disk Cruzer Glide 32 GB and 8Gb can't be copied to.

  - by chrisfs

  I have Ubuntu 12.04 with a kernal of 3.0.0-17-generic (#30-Ubuntu SMP Thu Mar 8 17:34:21 UT When I tried to copy files to a San Disk Cruzer 8gb usb drive, the copy process went a short way and then completely stopped. Although I have copied items to the USB drive from my PC before, this time the files would start quickly enough but always stop shortly after starting. I figure the 8 gb was bad, so I went and got a brand new 32 gb usb drive from a store, unpackaged it and plugged it in, still unable to copy to the usb drive. So is there some kind of incompatibility or issue where San Disk Cruzer Glides are no longer supporting it. Is there an obscure setting that I am missing? Any help would be appreciated

• Windows 8 will only recognize the Blu Ray ROM, if the install disk is present at boot time [migrated]

  - by aceinthehole

  If I have the install disk in the blu ray ROM drive at boot time and subsequently remove the disk and replace it with blu ray media everything functions as I'd expect. However, if I have no media present, or another disk in the drive at boot time, then windows 8 does not seem to recognize that the blu ray player is even present in the computer. It is not present in the 'my computer' screen, device manager does not show the player, and scanning for new hardware yields nothing. It seems that the driver is installed and working as expect, what is it about having the windows 8 install disk in the drive or not that would cause this kind of behavior?

• What about the performance enhancement when using an SSD as the main disk?

  - by motumboe

  I'm planning to buy a new PC and I am thinking about using an SSD as the main disk. I'd also use a standard spinning disk and I'd mount it to /home. To the people already using such a setup: does this induce a practical, noticeable enhancement in performance? I think that access times, rather than transfer rates, are the more useful feature of SSD's. I would like to know if they have a noticeable effect on a desktop installation of Ubuntu. Thanks in advance!

• Windows 7 Extend C Volume to Unallocated Space

  - by user327777

  a while back I installed Ubuntu and then later uninstalled it by I think deleting the partitions and recovering the windows 7 boot loader. I am not that experienced with partitioning yet. As you can see here there are two partitions that are now unallocated. The 9gb one is a recovery or something that came with the computer. How can I extend my C partition to use both of those? I do not want to have that much storage just wasted sitting there. Currently when I right click on C and hit extend the wizard pops up but there is no available space to extend. http://i.imgur.com/VxEkdyR.png http://i.imgur.com/DdFZWX9.png Thanks everyone!

• DVD Drive Has Stopped Recognizing Discs

  - by ricree

  My DVD drive no longer recognizes dvds, but does recognize CD-ROMs. When a DVD is in the drive, the computer continues to act as though there is no disc in the drive. However, when a normal CD-ROM is in the drive, it appears to work normally. I have tested on several discs, both video and game, and the behavior is consistent. I have also tested this on both Windows Vista and Ubuntu 9.10, and the issue remains the same. Can anyone recommend a way to fix this?

• Move hibernate file to a different drive

  - by Kamarey

  Is it possible to move a Windows hibernate file to a different drive? E.g. if I have Windows installed on C, I want it's hibernate file be on D. Eee... just thought that I wanted to ask this question about hibernate file, not the page file. Don't know where the page file came from. Sorry:) So the question is about hibernate file. But no problems with all answers about page file. (Edit: The original question title was "Move page file to a different drive")

• How bad is it to use a virtual file system with VMWare? [closed]

  - by user30997

  IT is running a series of VMs that we'd like to see optimized further: if the VMs' are Windows XP, storing their NTFS images out to the virtual disk (ext3) provided by Linux/VMWare, how much of a hit are we taking - as opposed to having a partition of the host hard drive formatted NTFS to eliminate the translation layer and the extra level of operating system IO preparation?

• write cache and write sequence order

  - by excanoe

  ok, here i have some weird question: let say we have some binary file (.log), and sequence of write operations, for example log1, log2, log3 and each has some block size n (raw data). question: can I be sure that log1,log2 and log3 sequences can be written in the correct order in ONE file, even if i have few cache levels (disk hardware and os level)? update very interested in what will be with records order (not with records) if we have software or hardware failure (reboot or another reason). update there can be some percent of write failures, but main question is: will write order stay correct?

• New Dell PE R710 - Storage Question

  - by rihatum

  Hi All, Dell PE R710, received from Dell in the following state : Windows Disk 0 1800GB ( Volume C & D ) Windows Disk 1 526 GB (Volume E ) Perc6i Integrated Raid Controller 6 x 500GB Nearline SAS 7200RPM HDDs Raid 5 Configuration with two Virtual Disks I have installed Dell open Manage and it shows the following : Virtual Disk 0 - State : Background Initialization ( 7% ) Virtual Disk 1 - State : Background Initialization ( 25% ) Now when I click on Virtual Disk 0 it shows me all 6 Disks and the same happens when I click on Virtual Disk 1 it displays all 6 disks. But when I click on Storage Perc6i Connector 0 I get 4 Physical disks with the following numbers : Physical Disk 0:0:0 Physical Disk 0:0:1 Physical Disk 0:0:2 Physical Disk 0:0:3 When I click on Storage Perc6i Connector 1 I get 2 Physical Disks Listed in the following way : Physical Disk 1:0:4 Physical Disk 1:0:5 I am a little confused in this description, does this 1:0:4 interprets to Controller1, Disk4. Does this integrated raid card have two controllers coming out of it ? Also, When I first switched on the machine, the boot partition was showing 1GB Available out of 40GB, now its showing 38GB available out of 40GB. Is this because the Virtual Disks are still Initializing ? Any recommendations or suggestions ? Also, this server have 6 x 500GB NearLine SAS Hard drives, what would be a good raid config ? We are planning to use it for Hyper-V with quite a few (7 or 8) virtual servers, your suggestions would be helpful. Also, while the virtual disks are in a initialization state, can I destroy and re-create the raid configuration ? I would have to do it at the BIOS CTRL-M ? Thanks and Regards

• Reinserted a RAID disk. Defined as foreign. Is import or clear the correct choice?

  - by Petrus

  I have re-inserted a RAID disk, on a DELL server with Windows Server 2008. The drive-status indicator was changing between a green and amber light, and the monitor gave the following message: There are offline or missing virtual drives with preserved cache. Please check the cables and ensure that all drives are present. Press any key to enter the configuration utility. I pressed a key and the PERC 6/I Integrated BIOS Configuration Utility showed that the RAID Status for that disk was Offline. After reinsertion of the disk the monitor is giving the following message: Foreign configuration(s) found on adapter. Press any key to continue or ‘C’ load the configuration utility, or press ‘F’ to import foreign configuration(s) and continue. After checking around on the net I am uncertain if I should choose import or clear. I cannot find out if an import means importing information from the array/system to the now foreign disk or the other way, i.e. importing information from the foreign disk to the array/system that was actually working fine. Also; if clear is a necessary thing to do ahead of a rebuild of that disk, or if clear means to clear the system to somehow make it ready to import the information from the foreign disk to the array/system, which is not what I want. I imagine that making the wrong choice here might be fatal. Please help clearing this out by telling what to choose and why.

• Cluster Node Recovery Using Second Node in Solaris Cluster

  - by Onur Bingul

  Assumptions:Node 0a is the cluster node that has crashed and could not boot anymore.Node 0b is the node in cluster and in production with services active.Both nodes have their boot disk mirrored via SDS/SVM.We have many options to clone the boot disk from node 0b:- make a copy via network using the ufsdump command and pipe to ufsrestore - make a copy inserting the disk locally on node 0b and creating the third mirror with SDS- make a copy inserting the disk locally on node 0b using dd commandIn this procedure we are going to use dd command (from my experience this is the best option).Bare in mind that in the examples provided we work on Sun Fire V240 systems which have SCSI internal disks. In the case of Fibre Channel (FC) internal disks you must pay attention to the unique identifier, or World Wide Name (WWN), associated with each FC disk (in this case take a look at infodoc #40133 in order to recreate the device tree correctly).Procedure:On node 0b the boot disk is c1t0d0 (c1t1d0 mirror) and this is the VTOC:* Partition  Tag  Flags    Sector     Count    Sector  Mount Directory      0      2    00          0   2106432   2106431      1      3    01    2106432  74630784  76737215      2      5    00          0 143349312 143349311      4      7    00   76737216  50340672 127077887      5      4    00  127077888  14683968 141761855      6      0    00  141761856   1058304 142820159      7      0    00  142820160    529152 143349311We will insert the new disk on node 0b and it will be seen as c1t2d0.1) On node 0b we make a copy via dd from disk c1t0d0s2 to disk c1t2d0s2# dd if=/dev/rdsk/c1t0d0s2 of=/dev/rdsk/c1t2d0s2 bs=8192kA copy of a 72GB disk will take approximately about 45 minutes.Note: as an alternative to make identical copy of root over network follow Document ID: 47498Title: Sun[TM] Cluster 3.0: How to Rebuild a node with Veritas Volume Manager2) Perform an fsck on disk c1t2d0 data slices:   1.  fsck -o f /dev/rdsk/c1t2d0s0 (root)   2.  fsck -o f /dev/rdsk/c1t2d0s4 (/var)   3.  fsck -o f /dev/rdsk/c1t2d0s5 (/usr)   4.  fsck -o f /dev/rdsk/c1t2d0s6 (/globaldevices)3) Mount the root file system in order to edit following files for changing the node name:# mount /dev/dsk/c1t2d0s0 /mntChange the hostname from 0b to 0a:# cd /mnt/etc# vi hosts # vi hostname.bge0 # vi hostname.bge2 # vi nodename 4) Change the /mnt/etc/vfstab from the actual:/dev/md/dsk/d201        -       -       swap    -       no      -/dev/md/dsk/d200        /dev/md/rdsk/d200       /       ufs     1       no      -/dev/md/dsk/d205        /dev/md/rdsk/d205       /usr    ufs     1       no      logging/dev/md/dsk/d204        /dev/md/rdsk/d204       /var    ufs     1       no      logging#/dev/md/dsk/d206       /dev/md/rdsk/d206       /globaldevices  ufs     2       yes     loggingswap    -       /tmp    tmpfs   -       yes     -/dev/md/dsk/d206        /dev/md/rdsk/d206       /global/.devices/node@2 ufs     2       noglobalto this (unencapsulate disk from SDS/SVM):/dev/dsk/c1t0d0s1        -       -       swap    -       no      -/dev/dsk/c1t0d0s0       /dev/rdsk/c1t0d0s0       /       ufs     1       no      -/dev/dsk/c1t0d0s5       /dev/rdsk/c1t0d0s5       /usr    ufs     1       no      logging/dev/dsk/c1t0d0s4       /dev/rdsk/c1t0d0s4       /var    ufs     1       no      logging#/dev/md/dsk/d206       /dev/md/rdsk/d206       /globaldevices  ufs     2       yes     loggingswap    -       /tmp    tmpfs   -       yes     -/dev/dsk/c1t0d0s6       /dev/rdsk/c1t0d0s6       /global/.devices/node@1 ufs     2       no globalIt is important that global device partition (slice 6) in the new vfstab will point to the physical partition of the disk (in our case slice 6).Be careful with the name you use for the new disk.

Next step is to encapsulate the boot disk in SDS/SVM and create the mirrors.In our case node 0b has metadevice name starting from d200. For this reason on node 0a we need to create metadevice starting from d100. This is just an example, you can have different names.The important thing to remember is that metadevice boot disks have different names on each node.13) Remove metadevice pointing to the boot and mirror disks (inherit from node 0b):# metaclear -r -f d200# metaclear -r -f d201# metaclear -r -f d204# metaclear -r -f d205# metaclear -r -f d206verify from metastat that no metadevices are set for boot and mirror disks.14) Encapsulate the boot disk:# metainit -f d110 1 1 c1t0d0s0# metainit d100 -m d110# metaroot d10015) Reboot node 0a.16) Create all the metadevice for slices remaining on boot disk# metainit -f d111 1 1 c1t0d0s1# metainit d101 -m d111# metainit -f d114 1 1 c1t0d0s4# metainit d104 -m d114# metainit -f d115 1 1 c1t0d0s5# metainit d105 -m d115# metainit -f d116 1 1 c1t0d0s6# metainit d106 -m d11617) Edit the vfstab in order to specifiy metadevices created:old:/dev/dsk/c1t0d0s1        -       -       swap    -       no      -/dev/md/dsk/d100        /dev/md/rdsk/d100       /       ufs     1       no      -/dev/dsk/c1t0d0s5       /dev/rdsk/c1t0d0s5       /usr    ufs     1       no      logging/dev/dsk/c1t0d0s4       /dev/rdsk/c1t0d0s4       /var    ufs     1       no      logging#/dev/md/dsk/d206       /dev/md/rdsk/d206       /globaldevices  ufs     2       yes     loggingswap    -       /tmp    tmpfs   -       yes     -/dev/dsk/c1t0d0s6       /dev/rdsk/c1t0d0s6       /global/.devices/node@1 ufs      2       no  globalnew:/dev/md/dsk/d101        -       -       swap    -       no      -/dev/md/dsk/d100        /dev/md/rdsk/d100       /       ufs     1       no      -/dev/md/dsk/d105        /dev/md/rdsk/d105       /usr    ufs     1       no      logging/dev/md/dsk/d104        /dev/md/rdsk/d104       /var    ufs     1       no      logging#/dev/md/dsk/106       /dev/md/rdsk/d106       /globaldevices  ufs     2       yes     loggingswap    -       /tmp    tmpfs   -       yes     -/dev/md/dsk/d106        /dev/md/rdsk/d106       /global/.devices/node@1 ufs     2       noglobal18) Reboot node 0a in order to check new SDS/SVM boot configuration.19) Label the mirror disk c1t1d0 with the VTOC of boot disk c1t0d0:# prtvtoc /dev/dsk/c1t0d0s2 > /var/tmp/VTOC_c1t0d0 # fmthard -s /var/tmp/VTOC_c1t0d0 /dev/rdsk/c1t1d0s220) Put DB replica on slice 7 of disk c1t1d0:# metadb -a -c 3 /dev/dsk/c1t1d0s721) Create metadevice for mirror disk c1t1d0 and attach the new mirror side:# metainit d120 1 1 c1t1d0s0# metattach d100 d120# metainit d121 1 1 c1t1d0s1# metattach d101 d121# metainit d124 1 1 c1t1d0s4# metattach d104 d124# metainit d125 1 1 c1t1d0s5# metattach d105 d125# metainit d126 1 1 c1t1d0s6# metattach d106 d126

• Finding a shared HDD attached to the network from my F-13 machine

  - by Ramy

  Sorry for the slew of n00bie questions, but here is one more. I recently partitioned my 1.5TB harddrive according to this question I then bought this to attach the harddrive to my network. The problem is, how do I navigate to the hard drive to move files over the network to the HDD. should this be moved to serverfault? update: the disk isn't even showing up when i call "fdisk -l" (as root). How can I mount it if I can't even find it?

• How to create partition when growing raid5 with mdadm.

  - by hometoast

  I have 4 drives, 2x640GB, and 2x1TB drives. My array is made up of the four 640GB partitions and the beginning of each drive. I want to replace both 640GB with 1TB drives. I understand I need to 1) fail a disk 2) replace with new 3) partition 4) add disk to array My question is, when I create the new partition on the new 1TB drive, do I create a 1TB "Raid Auto Detect" partition? Or do I create another 640GB partition and grow it later? Or perhaps the same question could be worded: after I replace the drives how to I grow the 640GB raid partitions to fill the rest of the 1TB drive? fdisk info: Disk /dev/sdb: 1000.2 GB, 1000204886016 bytes 255 heads, 63 sectors/track, 121601 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Disk identifier: 0xe3d0900f Device Boot Start End Blocks Id System /dev/sdb1 1 77825 625129281 fd Linux raid autodetect /dev/sdb2 77826 121601 351630720 83 Linux Disk /dev/sdc: 1000.2 GB, 1000204886016 bytes 255 heads, 63 sectors/track, 121601 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Disk identifier: 0xc0b23adf Device Boot Start End Blocks Id System /dev/sdc1 1 77825 625129281 fd Linux raid autodetect /dev/sdc2 77826 121601 351630720 83 Linux Disk /dev/sdd: 640.1 GB, 640135028736 bytes 255 heads, 63 sectors/track, 77825 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Disk identifier: 0x582c8b94 Device Boot Start End Blocks Id System /dev/sdd1 1 77825 625129281 fd Linux raid autodetect Disk /dev/sde: 640.1 GB, 640135028736 bytes 255 heads, 63 sectors/track, 77825 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Disk identifier: 0xbc33313a Device Boot Start End Blocks Id System /dev/sde1 1 77825 625129281 fd Linux raid autodetect Disk /dev/md0: 1920.4 GB, 1920396951552 bytes 2 heads, 4 sectors/track, 468846912 cylinders Units = cylinders of 8 * 512 = 4096 bytes Disk identifier: 0x00000000
