I'm new to LVM2 troubleshooting, so please point me in the right direction if these are obvious error messages. The script 'amanda_snapshot.pl' removes yesterday's snapshot and creates a new snapshot, which amanda backs up some time later. Here's the output of this script, including error messages: amanda_snapshot.pl: umount /media/vm1optsnap amanda_snapshot.pl: lvremove -f /dev/vg0/vm1optsnap Logical volume "vm1optsnap" successfully removed amanda_snapshot.pl: lvcreate --snapshot --name vm1optsnap --size 10G /dev/vg0/vm1opt /dev/dm-9: stat failed: No such file or directory Path /dev/dm-9 no longer valid for device(253,9) Aborting - please provide new pathname for what used to be /dev/dm-9 /dev/dm-10: stat failed: No such file or directory Path /dev/dm-10 no longer valid for device(253,10) Aborting - please provide new pathname for what used to be /dev/dm-10 /dev/dm-11: stat failed: No such file or directory Path /dev/dm-11 no longer valid for device(253,11) Aborting - please provide new pathname for what used to be /dev/dm-11 Logical volume "vm1optsnap" created amanda_snapshot.pl: mount /dev/vg0/vm1optsnap /media/vm1optsnap What would cause these /dev/dm-* errors? How can I find out what's going on? Dane -- Dane Miller Systems Administartor Greatschools, Inc http://www.greatschools.net
