Comment 38 for bug 1096520

OK, on a non-luks encrypted bog-standard lvm2 install of the latest trusty tahr.
Note: the original bug was already solved. The case where the output of the lv-snapshot creation is directed to a file on the volume being snapshotted is a mixed bag with the latest trusty tahr. The first time it went OK; the second time I used a single verbosity flag, and it hung:
lvcreate -v -s -p r -L 700M -n oscopy /dev/mapper/ubuntu--vg-root 2>/root/log
(Tried both a few times, no -v no hang, at least one -v and it hangs.)
