[SOLVED] To change UUID of my swap partition

yahoosam · 08-30-2012, 04:04 AM

I am fed up googling on this thing
i used tune2fs but it is saying bad magic word
after that i got tune2fs is not for swap-partition

can any one help

tune2fs is for ext2/3/4 filesystems. Swap is its own filesystem. What do you actually want to achieve? To change a UUID on swap, recreate it with mkswap -U <UUID>

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.
