[SOLVED] fstab only has labels, not /dev/stuff needed for e2fsck

I need to run an e2fsck on one of my arrays, but looking in fstab it only has labels which I don't think work with e2fsck. How do I find out what the label really is so I can put that in the e2fsck command to check that?

Readlink /dev/disk/by-label/<whatever>

When I do Readlink /data it says command not found

Huh - readlink is in coreutils ...

Try "ls -al /dev/disk/by-label".

I'm booted into repair filesystem mode, and all I know is the label of it, not the /dev/whatever I need to e2fsck it

Don't try to interpret what I said, do what I said.

Are you saying literally dev disk then whatever my label is?

No, he is saying that you literally type in the command

Code:

ls -al /dev/disk/by-label

I get ls: /dev/disk/by-label no such file or directory

Post your fstab. Are you sure you are using labels vs UUIDs? Are you using LVM?
Are there any other directories in /dev/disk?

Maybe the blkid command will provide the necessary information.

This is the volume i'm trying to e2fsck

LABEL=/data /data ext3 defaults 1 2

only thing under /dev/disk is by-path, which then has like 20 things under it.

looks like blkid does give me the /dev/whatever of each label!
