Description Marian Csontos 2012-12-06 07:51:41 EST
Description of problem:

Caused by commit bf274137 - Use lv_is_active instead of lv_info() - the refactored code is not equivalent to original and function fails when LV is inactive instead of setting variable to 0.

This was fixed by commit 400f6442861.

This is covered by STS and (modified) unit tests.

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:

> #!/bin/bash
> VG=vg
> lvcreate -L 300M $VG -n origin
> lvchange -an $VG/origin
> lvcreate -s /dev/$VG/origin -c 32 -n snap_of_inactive -L 100M
Actual results:
snapshot fails with following message:
> One or more specified logical volume(s) not found.

Expected results:
operation should succeed
