I have a 3TB raid, which was made originally with OPEN MEDIA VAULT, a media server. I have recently uninstalled OPEN MEDIA VAULT from the server and installed ubuntu 13.10.

The only problem I'm having is that I can't mount the raid disks and I DON"T want to lose the data at all, it's all my vital information.

Here's what I've tried:

mkdir /media/3TBRaid
// And then the mount command
sudo mount -t ext4 /dev/sdd/ /media/3TBRaid

This returns 'Mount: wrong fs type, bad option, bad superblock on /dev/sdd, missing codepage or helper program, or other error. In some cases useful info is found in syslog - try dmesg | tail or so'

I'm fairly new to LINUX in general, so please don't yell at me :)

The two drives, that I actually want to mount as one are device:

1: /dev/sdd
2. /dev/sdc

The type of both of these drives are 'linux_raid_member'

Could someone please help me on how to correctly mount the two drives as one without loosing my data?

as mount specified, something wrong with the FS(file system).
Try this: (It'll format the drive with ext4 format)

 mkfs.ext4 /dev/sdd 

If format successes then try these mounting steps again

mkdir /media/3TBRaid
// And then the mount command
sudo mount /dev/sdd/ /media/3TBRaid

hope it helps .!!

wouldn't that get rid of my data though? I can't stress enough that I don't want to loose this data :( –  Shannon Sep 9 '13 at 4:31
yes, that would be a problem... are you sure that it's a ext4 drive ...!! –  user182904 Sep 9 '13 at 4:36
on all my other drives, the type is ext4, but on the two mentioned above, they both say type='linux_raid_member' –  Shannon Sep 9 '13 at 4:38
but the mount command was for mounting a ext4 FS(drive). i found this article link –  user182904 Sep 9 '13 at 4:45
Yes as I mentioned I don't know Linux that well –  Shannon Sep 9 '13 at 4:45

From your error messasge

bad superblock on /dev/sdd, missing codepage or helper program, or other error.

That sounds , something wrong with that device. use fsck to check the and fix the possible error.

fsck -y /dev/sXX

mention your partition there to check and automatically fix the errors in your partition.

hope that helps.

It's saying fsck.linux_raid_member: not found, is there a way of fixing this without loosing the data? –  Shannon Sep 9 '13 at 4:45
@Shannon , fsck -y /dev/sdd thats enough. –  raaz Sep 9 '13 at 4:46
I did that already, What I posted in my comment is what that comment returned –  Shannon Sep 9 '13 at 4:49
