RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

Red Hat Product Errata RHBA-2013:0501 0 normal SHIPPED_LIVE lvm2 bug fix and enhancement update 2013-02-20 21:30:45 UTC

Description Marian Csontos 2012-12-06 12:51:41 UTC 
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):
lvm2-2.02.98-4.el6

How reproducible:
100%

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
