[SOLVED] UUID mismatch

blackhole · 2009-02-15 21:18:32

Hi there,

being a Linux noob I'm always curious how things work. I've noticed that fstab is using a UUID to mount my /dev/sda4 under root. When I consulted the manpages I learned that the UUID can be displayed via "xfs_admin -u".
When I tried that I was suprised as the UUID xfs_admin gave me for sda4 is different from the one in fstab. Still my hard drive is mounted properly and the system is running fine.

So how can that be? I've double checked the UUID and device number. No typo there. So is it magic then?

Does anybody have any idea about that?

TIA,
Blackhole

strange.
I think xfs_admin is a tool specific to xfs filesystem (I don't know this filesystem). is your root partition in xfs ?
you can also check the uuid with blkid :

blkid -s UUID /dev/sda4

(I think the system uses blkid to fill fstab)

Ah, ok. No, it's ext3. I'll check blkid and come back to you. ;-)

Yup, that was it. The UUID I got from blkid matches the one in fstab.

Thanks a lot for teaching a noob, nowahn.

Take care,
