Mount raid volume command line

Question

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!

Solution

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 :(

[user7581305]

yes, that would be a problem... are you sure that it's a ext4 drive ...!!

[Shannon]

on all my other drives, the type is ext4, but on the two mentioned above, they both say type='linux_raid_member'

[user7581305]

but the mount command was for mounting a ext4 FS(drive). i found this article link

[Shannon]

It's saying fsck.linux_raid_member: not found, is there a way of fixing this without loosing the data?

[Shannon]

Yes as I mentioned I don't know Linux that well

@Shannon , fsck -y /dev/sdd thats enough.

[Shannon]

I did that already, What I posted in my comment is what that comment returned

I managed to get it mounted using the post that you sent, although I believe I now have to get all the data off the drives, then reformat them? Is that correct or is there a way of fixing this do you think? I have edited my post with the output of that command

[user7581305]

that would be a better option :) and make some backUP of your vital data, i mean if it's important,it needs a backUP. and nice everything worked fine for you ...:)
