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.

Description Corey Marthaler 2012-09-26 21:01:57 UTC 
Description of problem:
This is basically bug 858874, but with a mirror volume being converted instead of a linear volume. I'm not even sure if this is or is not supported, but bug 855171 appears to imply that it's not.


[root@taft-04 ~]# lvcreate -m 1 -n mirror -L 100M TEST
  Logical volume "mirror" created

[root@taft-04 ~]# lvs -a -o +devices
  LV                VG   Attr     LSize   Log         Copy%  Devices
  mirror            TEST mwi-a-m- 100.00m mirror_mlog 100.00 mirror_mimage_0(0),mirror_mimage_1(0)
  [mirror_mimage_0] TEST iwi-aom- 100.00m                    /dev/sde1(0)
  [mirror_mimage_1] TEST iwi-aom- 100.00m                    /dev/sdf1(0)
  [mirror_mlog]     TEST lwi-aom-   4.00m                    /dev/sdg1(0)

[root@taft-04 ~]# lvconvert --thinpool TEST/mirror
[root@taft-04 ~]# echo $?
0

[root@taft-04 ~]# lvs -a -o +devices

[root@taft-04 ~]# lvcreate --virtualsize 1G --thinpool TEST/mirror -n origin
  Logical volume mirror is not a thin pool.
