Understanding LVM UUIDS
I feel I should move my entire /etc/fstab over to using uuids
However after installation I added the following line
/dev/raid/bak /bak ext4 defaults 0 2
which I now need to convert to a uuid (/dev/raid/bak is an lv on the
"raid" volume group)
if I look in /dev/disk/by-id I can locate the following
lrwxrwxrwx 1 root root 10 Jun 21 19:20 dm-name-raid-bak -> ../../dm-0
which shows me that this has been mapped to /dev/dm-0
However, I now have two options
in /dev/disk/by-id there is the following (excuse the word wrap)
lrwxrwxrwx 1 root root 10 Jun 21 19:20
dm-uuid-LVM-25HQ5BuXqjSs2y53Aj4C8zMHEX1ZrgBieFN7ln0AYSPSwzxCh5ylxoM3kRzS9gCe
-> ../../dm-0
and in /dev/disk/by-uuid (again excuse the word wrap)
lrwxrwxrwx 1 root root 10 Jun 21 19:20
f3408fda-0649-414f-8446-c01cf4e07558 -> ../../dm-0
There seems to be no correspondence between them
Which do I use, and what does the other one mean?
