Recently, I've tried to create a snapshot of my /root folder in 10.04 (I remember to have done so a couple of times without trouble).
I used the command
lvcreate -L10G -s -n rootsnapshot /dev/server/root
Without a hint of HDD activity, Gnome (?) hangs up - I can move the mouse, and the clock is moving on, but I can't click on anything. No HDD activity, and this goes on forever (after a while, the whole system locks up). This happens each time when I try to create a snapshot.
What could be the problem?
