Ubuntu :: Software Raid Does Not Mount On Startup?
Jul 18, 2010
I am running 64bit ubuntu 10.04. I have an nvidia software raid formatted with ntfs. The raid only mounts about every 10-15 boots. It is completely random on when it will mount. I even have included "force" in the ntfs-3g mount options.
Also, possibly related, many times ubuntu will not even load unless I load windows first and then restart. I run Ubuntu on its own partition using ext3, so this makes no sense.... It makes me scared to run a computer with only Ubuntu because it seems Ubuntu cannot load unless window loads before it! I could understand this if Ubuntu was formatted as NTFS, but the only NTFS drive Ubuntu sees is the raid, which is not mounting anyways, so why is it dropping to the command prompt?

I am struggling with getting an sshfs mount mounted on system boot. I have a script that mounts the sshfs for "userA". When userA runs the script all is well - user A can access the remote filesystem, root user can't see it as expected. The basic command is: sshfs userA@remote host:/home/userA /home/userA/mountdir -p 21212 -o password_stdin < passwordfile. I can prepend the sshfs command in the script with su - userA -c and when I run this script logged in as root all is well, userA has access and all is well. If I then put this script in /etc/init.d and reference it properly in the rc. directories the mount doesn't happen. If I prepend the sshfs command with sudo, same thing. Logged in as root I can run the script and UserA has access. Run the script in /etc/init.d during startup and the mount doesn't happen. Echoing text to a log file shows that the script is being executed but no mount happens.

I've just installed ubuntu 10.10 (64bit) on my 1TB drive where as I have my windows drives on a seperate 2x 1TB drives in RAID and am not exactly sure how to mount it.
I am not finding it under computer or under NTFS configuration tool and when I click mount under storage device manager it does nothing, although does detect the RAID array as /dev/sda2

We have 4 HDs on our server. One of them broke last night. I could see a message on the server and after restarting the S.M.A.R.T. on the BIOS was recognizing one HD as bad. After removing the failing HD, the server is now up and running. I do not remember how I configured the HDs. During the installation I had a few problems and I change a few times what I wanted to do. I am sure I had at least a RAID0 with 2 disks but I could have put all the 4 disk in the RAID having 2 disks as spare drives or I may have created another volume for the other 2....
dmraid return: No raid disks
Code:
$ sudo dmraid -ay -vvv -d

MountManager seems to report that sda and sdb belong to linux_raid_member.
However there is no mount point.
Questions:
1-How do I find how the disk were and are configured?
2-How can I find what was on the disk that died? (Was it a spare drive or one of the 2 in mirror)?
3-What do I need to do now to be sure that the mirroring is working OK? (considering that there is a spare drive). Do I need to use a command to let ubuntu mirror the drive on the new one?
4-What do I need to do when I get a replacement of the broken disk?
5-What is an utility that can show me easily how the disks are configured and eventually makes a change.

I have recently had a problem with my 10.04 server machine. It will not boot, it seems to be taking forever on the loading screen (normally headless server, but I connected monitor when I couldn't ssh), but that's not why I'm here.
Knowing that I do rsync backups every night at midnight of my machine I just bit the bullet and formatted my / partition. Reinstall went fine, I turned off automatic updates (I suspect an update caused the problem) But now I cannot mount my jmicron raid 1, which is where my rsync backup is (doh!).
sudo fdisk -l
Code:
WARNING: GPT (GUID Partition Table) detected on '/dev/sdd'! The util fdisk doesn't support GPT. Use GNU Parted.
Disk /dev/sdd: 1000.2 GB, 1000204886016 bytes

I had to recently reinstall ubuntu because 10.04 started acting up on me. I reinstalled 9.04 but I don't know how to mount my RAID drive without messing with the data that's already on there. I have the UUID for the RAID but fstab isn't able to find it. I also previously used RAID software but I don't remember which one I used. how to mount my drive so that ubuntu can see it?

I had run out of space on a 30GB raid1 partition so I rebuilt it as I had three 30GB partitions on a pair of 120GB drives. I stopped the array and used gparted to create a single 120GB partition on one of the disks. I then copied the data from all three partitions on the other drive onto this newly cleared space, before zapping that too. So I now had two drives with identical single partitions, one of which had all my data and lots of space. I used mdadm to create a new array from the two disks, which looked good. It immediately started to resync the data onto the second drive. However, when I tried to mount the new array this is what I get:
Code:
bob@zaphod:~$ sudo mount -t ext4 /dev/md0 /media/raid/
mount: wrong fs type, bad option, bad superblock on /dev/md0,
missing codepage or helper program, or other error
[code]....
I can mount the drives independently and GOOD NEWS the data is there! However, how can I get round this problem and mount the raid array.

I want to have a secondary hard drive mount at boot, mainly because it happens to be the home drive. But I have to manually mount it after I boot.
Any way to get "places" to mount on startup under 10.10?

Could any RAID gurus kindly assist me on the following RAID-5 issue?I have an mdadm-created RAID5 array consisting of 4 discs. One of the discs was dropping out, so I decided to replace it. Somehow, this went terribly wrong and I succeeded in marking two of the drives as faulty, and the re-adding them as spare.
Now the array is (logically) no longer able to start:
mdadm: Not enough devices to start the array.Degraded and can't create RAID ,auto stop RAID [md1]
I was able to examine the disks though:
Code:
root@127.0.0.1:/etc# mdadm --examine /dev/sdb2
/dev/sdb2:
Magic : a92b4efc
Version : 00.90.00
code....
Code:
mdadm --create --assume-clean --level=5 --raid-devices=4 /dev/sda2 /dev/sdb2 /dev/sdc2 /dev/sdd2
As I don't want to ruin the maybe small chance I have left to rescue my data, I would like to hear the input of this wise community.

After reformatting a usb drive with gparted, no usb stick will automount when I plug it in anymore. If the usb is in place at startup, however, it is recognized and mounted.The media will show up in fdisk and disk utility, but there is no link to it in Places > Computer. I have no trouble manually mounting, but I would rather not have to go through the hassle each time I plug in my flash stick. I am running Ubuntu 10.10 64bit

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 a CentOS 5 production server with multiple OS-managed RAID-1 sets. I'd like to add a new mirrored set and move the /var partition to the new drives. On a non-RAID system I would boot from the install CD to edit fstab and copy the existing files to the new drive, but I'm pretty sure booting off the install CD does not recognize my RAID setup.

After having solved my raid5 creation problems, I'm running into a new one: the RAID is just impossible to mount through fstab. I get a wonderful "The disk drive for /dev/md0 is not ready yet or not present.
Continue to wait or press S to skip mounting or M for mount recovery."
Once the system has booted, I can perfectly run a mount /dev/md0 /media/raid and mount it manually.
I've already tried mdadm.conf with UUIDs, with device names, tried several options in fstab, xfs and ext4 filesystems, nothing to do, it won't mount.
All this is running under Ubuntu 10.04 server, kernel: 2.6.32-25 server, mdadm 3.1.4 (from a Debian sid)
Here's my mdadm.conf:

The entry in my fstab:

I work at a school where we are experimenting with Ubuntu 10.10. On our Windows machines, when the users sign in, their "U:" drive automatically mounts up so that can access their network shared storage. Is there a way to set this up in Linux so it automounts, rather than them have to go and find it out on the network every time?

I've been trying to unsuccessfully auto-mount my drives when starting up. I've made a script that sets me to the root using "sudo -s" and then mounts the drives. The commands to mount the drives work properly when entered into the command line, but when I try running them from an executable, they don't work. What might I be missing?

i want to use this line:
[code]...
to mount my volume at start up. it prompts for my truecrypt password(TCP) to open my files. so far i can put it in in the "Startup applications" but it needs root rights.. so it prompts for my root password and then again for my TCP. id like it to only ask for my TCP. i tried just putting the command and then also putting the command in a bash script and calling it from there.

I was trying to automount a few NTFS partitions last night. Upon reboot, I got the following error messages.
/device/sda2 ... is not ready or present
/device/sdc2 ... is not ready or present
Then Ubuntu just freezes. I am using Ubuntu Natty, if that helps. I am currently unable to get into Ubuntu without a LiveCD.

Is there a way for me to mount a raid array member directly without using any of the raid tools? For instance, I have a raid 1 array that contains /dev/sda1 and /dev/sdb1. How can I mount /dev/sda1 or /dev/sdb1 directly? Doing mount /dev/sda1 <mnt point> does not work. If I try specifying the filesystem type with -t this doesn't work either.

In a nutshell, our RAID 1 array was rendered broken and we were advised that core lib files were missing and the OS needed to be reloaded... a quote from our server host:"The OS is not healthy.This server will need a reinstall.
Libs are missing." This was after having replaced what we though was a faulty /dev/sdb. So they reloaded the OS (Debian 5.0.2 x86_64) on 2 FRESH drives, and installed the old /dev/sda as /dev/sdc once the reload was completed. Here's the output of /etc/fstab on the fresh install so we know what we're working with:
Code:
debian:/BAK# cat /etc/fstab
# /etc/fstab: static file system information.
#
# <file system> <mount point> <type> <options> <dump> <pass>
[code]....
The one problem I see myself running into is /dev/md1 and /dev/md2 are currently in use by the new system, so I cannot mount it there. I should also note, reloading the OS is a viable option if needed as we haven't started configuring the server yet. So if we need to reinstall the OS and assign the NEW RAID arrays to something other than /dev/md1 and /dev/md2 then we can do that.
