Yeah, what he said.

To find out where it's gone, do 'sudo -i' to become root, then:

  fdisk -l

That will list all the partitions your system can see. One of the disks
should look familiar. Your partition's probably now called something
like /dev/sdq5 (the number should be the same).

The UUID stuff is a way of referring to a specific partition regardless
of what physical device it's on --- this is vital when you're using SCSI
because the device name may change depending on the order in which the
disks power up. It's easy enough to cope with: instead of referring to
the partition as /dev/sdq5, you now refer to it as UUID=... where ... is
a long hex ID. vol_id will tell you the UUID of a partition. So once
you've found it, do:

  vol_id /dev/sdq5

...and it'll list a bunch of info as to what the partition is:


Then just copy the UUID from ID_FS_UUID into your fstab, and Robert is
your mother's brother:

UUID=499d1dae-53d3-4b1b-bbbd-3c77df750fa9 / jfs defailts 0 0
