Hello,
I have an OpenSuSE 11.4 based Xen server. I use LVM as the 'store' for
VM 's and I'm trying to make use of snapshots for backup.
However I discovered that often removing a snapshot fails -
unfortunately it's quite unpredictable, as sometimes it works on next
try but sometimes it fails 20 times in a row - making it very unpleasant
for scripting...
Even when it succeeds it give's me a message 'give up on open_count' -
and I couldn't quite find what it means.
Here's what I've been trying by hand:
# lvcreate -s /dev/vm_store/test_vm1 -n "backup_test_vm1" -l 100%ORIGIN
Logical volume "backup_test_vm1" created
# lvremove -f /dev/vm_store/backup_test_vm1
give up on open_count
Logical volume "backup_test_vm1" successfully removed
# lvcreate -s /dev/vm_store/test_vm1 -n "backup_test_vm1" -l 100%ORIGIN
Logical volume "backup_test_vm1" created
# lvremove -f /dev/vm_store/backup_test_vm1
give up on open_count
Logical volume "backup_test_vm1" successfully removed
# lvcreate -s /dev/vm_store/test_vm1 -n "backup_test_vm1" -l 100%ORIGIN
Logical volume "backup_test_vm1" created
# lvremove -f /dev/vm_store/backup_test_vm1
Can't remove open logical volume "backup_test_vm1"
Am I doing something wrong?
Is this 'expected' and should I just keep re-trying in a loop until it
succeeds?
Thanks, Danilo
