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.

Comment 1 Corey Marthaler 2009-10-14 21:04:15 UTC 
FYI - the current code does not forget to check when changing an existing LV from non-clustered to clustered regardless of whether or not it's currently active.

[root@taft-01 ~]# lvcreate -L 12M -s taft/clinear
  Logical volume "lvol0" created
[root@taft-01 ~]# lvs -a -o +devices
  LV       VG         Attr   LSize   Origin  Snap%  Move Log Copy%  Convert Devices

  LogVol01 VolGroup00 -wi-ao   9.75G                                        /dev/sda2(1868)

[root@taft-01 ~]# vgchange -c y taft
  Volume group taft contains snapshots that are not yet supported.
[root@taft-01 ~]# vgchange -an taft
  0 logical volume(s) in volume group "taft" now active
[root@taft-01 ~]# vgchange -c y taft
  Volume group taft contains snapshots that are not yet supported.
Comment 2 Corey Marthaler 2009-10-14 21:11:31 UTC 
In fact there may even be a bug in here, though I think I've brought up the fact that lvm will activate in single machine mode the same volume on multiple nodes.

[root@taft-01 ~]# vgchange -aye taft
  2 logical volume(s) in volume group "taft" now active

[root@taft-01 ~]#  lvs

Comment 6 Corey Marthaler 2011-02-15 18:09:50 UTC 
bug 677739 should block this feature.
Comment 7 Corey Marthaler 2011-03-16 19:16:20 UTC 
Marking this FailsQA until the fix for 677739 is included.
Comment 8 Peter Rajnoha 2011-03-18 09:46:53 UTC 
6777739 now in POST (upstream in version 2.02.85), marking this one POST as well.
Comment 10 Corey Marthaler 2011-03-18 20:11:51 UTC 
677739 has now been verified. Marking this feature verified as well with the latest rpms.

Comment 11 Corey Marthaler 2011-04-11 18:40:31 UTC 
Just a note that bug 694164 (targets not resumed when creating multiple snapshots of mirrors) may be seen when attempting this feature. This may require a note in the docs.
