I have 2 identical disks originally configured as a pair for a server. Each of the disks has 2 partitions dev/sdb1,dev/sdb2. The sdb1 partitions I had configured as a raid1 mirror. The sdb2 partitions were non-raid and used as extra misc. Space. Further, the raid setup is also encrypted using dm-crypt luks. Now I want to redeploy each of the disks for new purposes. One of the disks i want to deploy exactly as before (keeping the partitions and content), however without being part of a raid array.
I've successfully deployed this disk into a new system and I am mounting the dev/sdb1 partition as dev/md0 because the disk is set to autodetect raid. Actually I am using cryptsetup and mounting with mapper. Can I get rid of the setting for auto detect on this partition without losing the data, or breaking the encryption? I just want to mount the partition as a standalone encrypted disk. Is it as simple as doing crypt setup luksOpen /dev/sdb1 then mounting it with mapper? Or do I need to change the partition in some way. Or do I simply continue to operate it as a 'broken' raid array?
After an install of suse 11.4, one of my drives raid 0 (ichr9 intel) does not mount and is not recognized as being formatted in NTSF, while the other unit raid 0 (ichr9) is recognized without problems?
I need to copy data from a single HD, which used to be part of a Linux RAID 1. I've googled around, but can't find any clue how to mount partitions from this single HD.
Background: The HD comes from a linux based NAS box Synology DS207+. The NAS uses ext3 as filesystem. Both NAS disks are fine, but the other NAS hardware is dead and not worth repairing or replacing.
I have a Dell VOSTRO laptop that I use for windows Vista. I have an old disk drive that I put into a USB case and now I want to use that for a Debian system. I do not want to install grub on my laptops HDD, if I do I need to have the USB HDD plugged in everytime I boot and i find that a real pain. I installed Debian on the USB drive with no problem and when it asked where I wanted to install GRUB I picked the USB drive ( I think ). Now when I interupt the boot and tell it to boot from the USB drive grub comes up with the correct menu but when I pick Debian I get the following messages:
Booting 'Debian GNU/Linux Kernel 2.6.26-2-amd64' root (hd1,0) Filesystem type unknown partition type 0xde kernel /boot/vmlinuz-2.6.26-2-amd64 root=/dev/sdb1 ro quiet Error 17: Cannot mount selected partition
The RAID level 1 interested me because of its redundancy in both drives. And I successfully made it in a couple of partitions. But, I always did it after Linux installation. Then, I create both partitions, use 'mdadm' to create raidtab and RAID device (md0, for example) and then I format the RAID device with 'mkfs' and mount it.
Until there, it's all OK.
But my problem is to mirror ALL the hard disk, inclusive root partition. To do that, I guess I need no Linux installation, then create the RAID (md0, raidtab, etc) and after that install Linux in RAID device created.
But I'm new in Linux world and I have no idea how to do that.
I use Debian Lenny, so I need a solution that uses only the first DVD of this distribution.
I've just bought a HP mini compaq laptop. The laptop doesn't have any CD/DVD "reader". So i was forced to download the .iso file to install ubuntu in addition to Windows XP that was present when i bought it. To do so i used UNetbootin, and i used my only hard disk as a live CD. But when i wanted to install ubuntu, they told me to create a partition. The problem is that i can't. I have only one partition sda1(nfst) which covers the whole stockage memory, and an empty space(8Mo). I can't acceed to any of the resizing or modifying options to edit the nfst partition. The only options are manage flags and umount. When i click on this one, they tell me : # umount /cdrom : cdrom is busy.
I have recently installed Debian on my NAS server. I have also configured Samba for sharing the home directory of a nas user i.e. /home/nas To this directory I have read/write from a windows machine using the nas user credentials. When I mount my RAID partition /dev/md0p1 to the /home/nas directory, I then realize that all content in this directory (files and subfolders) is only owned by the root user. When trying to access from the windows machine the /home/nas directory, I do not have any write access, only read. I have tried both the nas and the root user credentials.
I have also attempted the change the ownership of the mounted RAID partition to the nas user with the -R recursive option, but I get for the internal files/subfolders an error "operation not supported".
How can I overcome this problem? - Is there something not done properly in the /dev/md0 array definition (i.e. ARRAY /dev/md0 level=raid1 num-devices=2 UUID=bddf8b69:c97967b5:cb104784:7fef7cc3 )?- Is there something not done properly in the /dev/md0p1 mounting (i.e. mount /dev/md0p1 /home/nas)?- Should I do any extra configuration before the mounting etc? I would really appreciate any kind of help I could get.
Some background info
b) After OS boot, when I do a: # cat /proc/mdstat, I get: Personalities : [raid1] md0 : active (auto-read-only) raid1 sda1[0] sdb1[1] 4200896 blocks unused devices: <none>
concerning Linux, mdadm, and creating RAID Array's in Debian. I've done a lot of reading and research on RAID both on this board and elsewhere (The Linux Documentation Project's Software-RAID HOWTO is especially good), but I've run across something that no one seems to explain, and I'm not sure why. I'm instructed to create partitions on the drives I wish to add to my array. These partitions inevitably take up the whole disk, and are always have their system IDs set to "Linux raid autodetect". What I don't understand is why, after creating these partitions, some guides then go on to create an array (say a RAID5 one) with just the disks themselves as members, while others go on to create the RAID5 array with the previously created partitions as members. E.g.,
I've installed debian squeezy recently and for some reason I have problems with mounting /home partition during startup.
There's an error:Mounting local filesystems...mount: special device /dev/mapper/isw_bbfedcffgi_Volume0p6 does not exist. failed
I've tried using fsck - no result the file system is healthy, I've tried formatting it once again (fresh copy, no user data) and it's not working. What is more mounting the partition manually goes well - I can read the data and write to it. All other partitions are ok.
I have no idea what's going on and why mounting /home fails. I've written this post on Polish debian users forum, but no response - only to give more info, so I'll put it here also:

The ext4 file system creation in partition #1 of Serial ATA RAID isw_fjidifbhi_Volume0 (mirror) failed. Not sure what's wrong? How do I solve this? This happens after I enter my login details and click next. Then it fails on the install screen with this error.
I am trying to install Ubuntu Server 10.04 on a home server I am making. I have 3 1-TB drives set up in RAID 5 via my mobo (ASUS M2NPV-VM). The installation detects that I have a RAID array, but when it goes to partition, all it shows me is the usb stick I am installing from.
I am having trouble mounting a partition on "sda", I opened thunar as root to try and set permissions to the partition so I could access it but when I open thunar as root I don't see the partition, if I open thunar without root privileges only then I can see the partition, I just can't access it, I get the error "Failed to mount "backup'.Not authorized to perform operation.
My desktop Debian Lenny installation is crashed. And I need to gain access to home directory! Partition is logical volume. I put HDD in a External HDD case and connected with my notebook (Debian Lenny) using USB.
I have a dual-boot with Debian and Windows7. I used Synaptic to install the ntfs packages, and Debian detects the windows partition, but when I double click it, it says something like "Failed to mount. Invalid mount option". Now I can mount it and navigate the folders, but ALL folders and files have permissions set to 700, and I can't change the permissions to access any of the files. Sure would be nice to be able to access my windows partition.
How can I mount a partition (sdb5) to be checked by Dazuko 3?This is my fstab file, but sdb5 is mounted twice: with "Linux_Dati__sdb5" (mount point) and "Linux_Dati" (partition label)
Storage information: 1st primary:SG 160G ATA 100 1st secondary:WD 160 ATA 133 SATA:WD 1000 2nd primary:DVD 2nd secondary:DVDRW
Winxp in 1st primary.I did a fresh install of lenny on 1st secondary.
info about lenny setup: 1.Partition list:/boot,/,/home,swap 2.Every partition is XFS except swap.
At the end of installion,lenny installed grub on (hd0) that is 1st primary.
Everything seems OK.Lenny runs OK.
But when I switch back to windows xp,the diskmgmt can not detect hdd's info and the system meets a problem of shutting down.
After many times of trying. I solved the problem by the following way. 1.Boot with windows xp's install CD and use fixmbr on (hd0). 2.Boot with lenny's install DVD , do a grub>root (1,0)>setup (hd1) After that,edit /boot/grub/menu.lst and change (hd0,0) to (hd1,0) and also (hd1,0) to (hd0,0). 3.Reboot and Press F8 for a boot menu then I can select which disk to boot. windows boot from 1st primary's mbr,lenny boot from lenny's grub.
The problem is caused by a bug between GRUB and windows' mbr and maybe more about GRUB and XFS.
I can't seem to get past step 6 of he installation of Ubuntu 10.04. I get the error: The ext4 file system creation failed... on single partition (no raid). I chose ' / ' as the mount point, and have tried with and without a swap drive. I'm installing on a Sony VAIO VGN-NS160D, and the HDD was previously formatted to NTFS. There's no other OS so I don't see any way of getting a command line to try a sudo fdisk..
Q1) I was wondering if it is possible to Dual boot Ubuntu with Windows XP on a 1TB RAID-0 setup ?
Q2) Also, is it possible to create a SWAP partition (for Ubuntu) on a NON RAID-0 HDD ?
Q3) Lastly... I read GRUB2 is the default boot manager... should I use that, or GRUB / Lio ?
I have a total of 3 HDDs on this system: -- 2x 500GB WDD HDDs (non-advanced format) ... RAID-0 setup -- 1x 320GB WDD HDD (non RAID setup) (The non RAID HDD is intended to be a SWAP drive for both XP and Ubuntu = 2 partitions)
I plan on making multiple partitions... and reserve partition space for Ubuntu (of course).
I have the latest version of the LiveCD created already.
Q4) Do I need the Alternate CD for this setup?
I plan on installing XP before Ubuntu.
This is my 1st time dual booting XP with Ubuntu.
I'm using these as my resources: - [url] - [url]
Q5) Anything else I should be aware of (possible issues during install)?
Q6) Lastly... is there anything like the AHCI (advanced host controller interface) like in Windows for Ubuntu?
(Since I need a special floppy during Windows Install...) I want to be able to use the Advanced Queuing capabilities of my SATA drives in Ubuntu.
sda is what I currently run to write this text, sdb is my former harddrive, connected via USB.
I want to access the root partition on sdb.
The problem is:
Code: Select allcryptsetup luksOpen /dev/sdb5 oldhd Enter passphrase for /dev/sdb5: root@x200s:/home/b# ls /dev/mapper/ control oldhd sda5_crypt x200s--vg-root x200s--vg-swap_1 root@x200s:/home/b# mount /dev/mapper/oldhd /mnt/ [b]mount: unknown filesystem type 'LVM2_member'[/b]
[Code] ..
Before all this, both sda and sdb where in the same volume group. I renamed the volume group of sdb to "oldDisk" using
Code: Select allvgrename <UUID> oldDisk
How I can access the data on the root filesystem of my sdb..
I am running the latest debian lenny OS and with kernel 2.6.26-2-686. I have a common /data partition for both Ubuntu and Debian which is ext4 file system. I am not able to mount this volume. The error message reads "unknown filesystem type ext4". How do I fix this. I searched the net and there was a link talking about this
I made a mistake in Gnome Disk utility tool. Instead of changing the options for a USB key, I changed the options of the root partition.
In Initial state, automatic options were desactivated. I just activated them. And after desactivacting them, I realized my mistake and switched back to "non automatic options".
By doing this, I suppose that defaults values were used since now, the system starts in command line mode and no more in graphic interface mode.
When I try the "startx" command, I get a "read-only" error.
With the command "sudo mount -o rw,remount /" the graphic interface is started.
Below is the configuration of the partition under the gnome disk utility tool :
"Mount at startup" is checked "Show in user inteface" and "Require additional authorization to mount" are unchecked
Mount options : nosuid,nodev,nofail,x-gvfs-show Mount point : /mnt/eb11d4d6-75db-XXXx-XXXx Identify as : /dev/disk/by-uuid/eb11d4d6-75db-XXXx-XXXx Filesystem type : auto
I do not want to change anything that could leat to a critical error. So what do you think I should do ?
It is gnome 3, debian jessie, nautilus file manager. Click ntfs partition from file manager, type password got error:
Code: Select allUnable to access “alldisksda5” Error mounting /dev/sda5 at /media/user1/alldisksda5: Command-line `mount -t "ntfs" -o "uhelper=udisks2,nodev,nosuid,uid=1000,gid=1000,dmask=0077,fmask=0177" "/dev/sda5" "/media/user1/alldisksda5"' exited with non-zero exit status 14: The disk contains an unclean file system (0, 0).

Why is this error? Windows has been shutdown normally. What to do?
