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?

Thankyou!

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 .!!

EDITED:

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
