LVM has lost the plot - "Couldn't find device with uuid...."
One of my users rebooted their Slackware 12.0 workstation to be greeted with the message "Couldn't find device with uuid ..." when LVM is detecting volumes.
I booted off an install disc so I could take a look and I can't find anything wrong :-/ Running pvscan finds all volumes and I can activate, mount and use the volumes as I normally would.
Does anyone know of a reason why the main boot would fail to detect the disk but booting from the install disc would detect it just fine? It was working ok just the other day!?
