Where did my files go?
I have an Openfiler NAS, which is no longer behaving well with our domain controller. I can log in fine as root via ssh, but cannot log in to any file shares as anyone via samba.
So, I want to can openfiler, and change it to Ubuntu.
I booted up with an Ubuntu 9.10 Desktop live CD, and installed mdadm, and rebuilt the array and mounted it on /mnt/raid.
I can access the disk. that's not a problem. I can get into the RAID array just fine (see screenshot).
However, when I navigate to /mnt/raid/mnt/storage/prim
It is there when I boot back into Openfiler.
How do I get to this via the Ubuntu live CD? My main goal is to use FTP to transfer off all the files that are in that directory to another box so I can reinstall this one.

Also be careful mounting the LVM, as it is possible to screw up the raid signature for the LVM I suggest you mount it as read only to not damage the raid or the journal block.

OK. I'll change to an Ubuntu 10 live cd and try it out.

Booted up with an Ubuntu 10 live cd, and wasn't given a recovery mode option. It started into the desktop session, and I got just as far as I did before. I can mount the array, but the directory I need is not showing.
I think you are dead on with it being an LVM. How would I mount the LVM via the Ubuntu 10 desktop session?
I used mdadm --auto-detect to find and assemble the raid array. cat /proc/mdstat shows the two RAID volumes....

Use lvscan to scan for Logical Volumes.
lvdisplay to display all the Volumes.
pvdisplay will display all the physical drives assigned to logical volumes.
See if you pick up any drives or lv's

This solution is only available to members.
To access this solution, you must be a member of Experts Exchange.
You will have to boot with a Ubuntu 10 CD to read the logical volume.
The recovery console should pick it up automatically.
If not, post the output of
ls -l /dev/mapper
from the recovery console.
You can just mount any device inside /dev/mapper using a normal mount.
