Actually i am using two hard disks with one server..
the second one is having same replica of currently running HD..
i changed UUID of LABEL="/boot" & LABEL="/" successfully
but in case of swap partition it is saying
Code:
tune2fs: Bad magic number in super-block while trying to open /dev/sdb2
Couldn't find valid filesystem superblock.
so i got that tune2fs is not for swap partition..
can you assist me other way to change UUID of swap-partition.
