869417 – is a --poolmetadata volume option required when converting a linear to pool

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 of problem:

[root@taft-04 ~]# lvcreate -n lv2 -L 100M VG

  lv2     VG    -wi-a---- 100.00m             /dev/sdb1(25)   

[root@taft-04 ~]#  lvconvert --thinpool VG/lv1
  Uknown metadata.

### Is --poolmetadata required?? If so can we enhance this error message to include the need for '--poolmetadata' to be present in the cmdline. I'm not sure since it wasn't required in the previous build (however that build resulted in bug 858874)

[root@taft-04 ~]#  lvconvert --thinpool VG/lv1 --poolmetadata VG/lv2
  Converted VG/lv1 to thin pool.

Comment 1 Zdenek Kabelac 2012-10-24 08:43:52 UTC

Yes, for this moment the only supported conversion is  with giving thinpool LV device name and poolmetadata  LVM device name.

Probably better explanatory message could be added to avoid confusion.

lvconvert will have more capabilities in the next version.
