Sorry to re-open this thread, but how can I obtain this uuid?? For
example. With one disk, uuid is showed:
[root@newc6srv by-uuid]# ls -la /dev/disk/by-uuid/
total 0
drwxr-xr-x 2 root root 80 Mar 28 13:19 .
drwxr-xr-x 4 root root 80 Mar 28 13:19 ..
lrwxrwxrwx 1 root root 10 Mar 28 13:19
0faf5e22-ff30-4ab8-a9ac-733c593eec40 -> ../../sda1
lrwxrwxrwx 1 root root 10 Mar 28 13:19
37501499-c52d-4a84-9ec8-778adf511ebd -> ../../sda2
but when I add two disks, uuid isn't showed:
root@newc6srv by-uuid]# ls -la /dev/disk/by-uuid/
total 0
drwxr-xr-x 2 root root 80 Mar 28 13:19 .
drwxr-xr-x 4 root root 80 Mar 28 13:19 ..
lrwxrwxrwx 1 root root 10 Mar 28 13:19
0faf5e22-ff30-4ab8-a9ac-733c593eec40 -> ../../sda1
lrwxrwxrwx 1 root root 10 Mar 28 13:19
37501499-c52d-4a84-9ec8-778adf511ebd -> ../../sda2
[root@newc6srv by-uuid]# ls -la /dev/sd*

Then, how can I obtain these uuids??
