HOWTO: Find out the label/UUID/ID for your disk
ls /dev/disk/by-label -lah
ls /dev/disk/by-id -lah
ls /dev/disk/by-uuid -lah
ls /dev/disk/by-id -lah
ls /dev/disk/by-uuid -lah
OR
sudo debugreiserfs /dev/sda2
and to set it to something or something else, but the partition must not be mounted.
sudo reiserfstune --label LABEL /dev/sda2
To change the UUID you can use the following. To generate a new UUID use the command below.
uuidgen
To change the uuid on ext2, ext3 or ext4 partitions use something like the following, remember to change the X to the correct drive and N to the correct partition number
sudo tune2fs /dev/sdXN -U (output from uuidgen)
and for reiserfs you can use either of these
sudo reiserfstune /dev/sdXN -U (output from uuidgen)
sudo reiserfstune /dev/sdXN -U random
sudo reiserfstune /dev/sdXN -U random
