[YLUG] fstab

[Harry Mills]

Hi,

You can find the UUID of a volume using the vol_id command. For example,
to find the UUID of /dev/sda1 on my system I do the following:
$ sudo vol_id /dev/sda1
ID_FS_USAGE=filesystem
ID_FS_TYPE=ext3
ID_FS_VERSION=1.0
ID_FS_UUID=0b3eb0fe-d708-4427-a0bb-cd3249e45070
ID_FS_UUID_ENC=0b3eb0fe-d708-4427-a0bb-cd3249e45070
ID_FS_LABEL=
ID_FS_LABEL_ENC=
ID_FS_LABEL_SAFE=

So I can see the UUID I need to use in /etc/fstab is
"0b3eb0fe-d708-4427-a0bb-cd3249e45070". Note that for other filesystems
this number may be quite different, for example NTFS drives will look
more like:
ID_FS_USAGE=filesystem
ID_FS_TYPE=ntfs
ID_FS_VERSION=3.1
ID_FS_UUID=BE507CCB507C8BC1
ID_FS_UUID_ENC=BE507CCB507C8BC1
ID_FS_LABEL=
ID_FS_LABEL_ENC=
ID_FS_LABEL_SAFE=
