Debian Installation :: 8.0 - Need To Mount Raid Partition
Dec 21, 2015
Have a new debian install on a asus h170m-plus (was going to use ubuntu but didnt support the hardware/software combo i needed)
Install is fine. but during install it didnt see my 1tb raid1 drive..
after reboot, debain boots great, and i can mount the raid drive in the file manager.
I can see it and in mtab it shows up :
"/dev/md126 /media/user/50666249-947c-4e8f-8f56-556b713a6b6a ext4 rw,nosuid,nodev,relatime,data=ordered 0 0"
How can I permanently add this mount point so it is found at boot up at /data...

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.,
mdadm --create --verbose /dev/md0 --level=5 --raid-devices=4 /dev/sda /dev/sdb /dev/sdc /dev/sdd
vs.
mdadm --create --verbose /dev/md0 --level=5 --raid-devices=4 /dev/sda1 /dev/sdb1 /dev/sdc1 /dev/sdd1
What's the advantage of using one over the other?

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:
ls -al /dev/mapper
crw------- 1 root root 10, 59 Nov 9 19:34 control
lrwxrwxrwx 1 root root7 Nov 9 19:34 isw_bbfedcffgi_Volume0 -> ../dm-0
lrwxrwxrwx 1 root root7 Nov 9 19:34 isw_bbfedcffgi_Volume01 -> ../dm-2
lrwxrwxrwx 1 root root 7 Nov 9 19:34 isw_bbfedcffgi_Volume05 -> ../dm-3
lrwxrwxrwx 1 root root 7 Nov 9 19:34 isw_bbfedcffgi_Volume06 -> ../dm-4

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.

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.

No matter which ubuntu version at 95% through the install it will complain that grub failed to install.
I'm installing this on an HP XW6600 with hardware raid striped.
I can use the supergrub rescue CD to boot to ubutu after, but whatever I do doesn't seem to get grub installed.
Any ideas on how to proceed? I'm guessing I need to install grub from scratch.

I just installed Debian 8.2 (Jessie). I couldn't find the way to mount the Windows 7 partition, at installation time.
¿Could you tell me how can I mount NTFS partitions in order that they be mounted at boot time and can be accessed (read and write) by any user?
I know, I should edit "/etc/fstab" file. But I don´t know very well how to modify it.
And... ¿Should I create the mount point directory, also?

About dual boot system with winxp and lenny.
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..

(This is for a 100% Clean install)
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.

I have two basically identical harddrives that are encrypted with LUKS containing a complete debian installation:
Code: Select allroot@x200s:/home/b# lsblk --fs
NAME FSTYPE LABEL UUID MOUNTPOINT
sda
├─sda1 ext2 0b851969-281e-4db2-8a5b-3798e801711b /boot
├─sda2
└─sda5 crypto_LUKS cfcf63ef-448a-4f72-9f58-8f7731cf3dfc
└─sda5_crypt LVM2_member 21CS3f-SQeQ-XcMr-kyDs-OPtR-egmT-HkvJAu
[Code] ....
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 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 ?
