Hi,
I've recently started getting errors when creating a snapshot. 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Path /dev/dm-9 no longer valid for device(253,9)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Path /dev/dm-10 no longer valid for device(253,10)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Path /dev/dm-11 no longer valid for device(253,11)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?

Please accept my humblest apologies to the list for this re-posting. I
inadvertently filtered linux-lvm messages into an unsubscribed IMAP
folder, and thus didn't see them post. I assumed I was a victim of
over-aggressive gray listing, when in fact I was just an over-zealous
filterer.
I realize that such a re-post after such a short period of time must
have appeared quite rude and demanding. Let me assure you that was not
my intention.
