Oh, an example of it working: # vol_id /dev/sda3 ID_FS_USAGE=filesystem ID_FS_TYPE=ext3 ID_FS_VERSION=1.0 ID_FS_UUID=9d2efd53-6b5a-4f84-86cc-def71269b7ca ID_FS_LABEL= ID_FS_LABEL_SAFE= # vol_id -t /dev/sda3 ext3 # vol_id -u /dev/sda3 9d2efd53-6b5a-4f84-86cc-def71269b7ca
It also shows just the label if you have one set (I don't on this disk...)
