Package: lvm2
Version: 2.02.133-1
Severity: normal
Snapshot creation reports a failure using Sid but not Jessie 8 Stable.
# lvs | sed 's/ *$//' | grep -e LV -e root

Creating a snapshot reports a failure.
# lvcreate -s -n rootsnap -L10G v1/root
Monitoring v1/snapshot0 failed.
Logical volume "rootsnap" created.
# lvremove -f v1/rootsnap
Logical volume "rootsnap" successfully removed
However if enough space is provided it does not.
# lvcreate -s -n rootsnap -L20G v1/root
Reducing COW size 20.00 GiB down to maximum usable size 16.07 GiB.
Logical volume "rootsnap" created.
That works on stable without any failures reported.
# lvs | sed 's/ *$//' | grep -e LV -e root

root e1 -wi-ao---- 5.59g
# lvcreate -s -n rootsnap -L4G e1/root
Logical volume "rootsnap" created
I have searched but I can't find any documentation on what monitoring
is happening here and what it means to have it failed. Even with that
failure report the LV created seems usable. But of course reported
failures should not be ignored.
