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 Robert Peterson 2011-04-08 14:49:39 UTC 
Sounds like we need to port this upstream patch back to RHEL6:

http://git.fedorahosted.org/git/?p=gfs2-utils.git;a=commitdiff;h=85ab1eeb40508dcc0f0a5c5ae63ca71dfb08c173
Comment 2 Robert Peterson 2011-05-26 17:56:41 UTC 
Patch 3e44524 was pushed to the RHEL6 branch of the cluster
git tree for inclusion into 6.2.  Changing status to POST
until this gets built.
Comment 3 Fabio Massimo Di Nitto 2011-05-27 06:47:30 UTC 
The original commit landed at the wrong time and I had to revert/reapply.

New sha1 is: b4029e885bf6d6fee7bee16172be873fa2329ec0
Comment 4 Nate Straz 2011-06-14 14:54:29 UTC 
Development needs to provide unit testing results.  Please show that UUIDs are printed in lower case with gfs2-utils-3.0.12.1-2.el6.

Verified against gfs2-utils-3.0.12.1-5.el6.x86_64

# gfs2_tool sb /dev/sdb1 uuid
current uuid = 7a16773f-fbae-8863-0b92-6d83ddfe5426

I also checked that the new command, tunegfs2, prints correctly
# tunegfs2 -l /dev/sdb1
tunegfs2 (Jun 23 2011 05:03:50)
...
Filesystem UUID: 7a16773f-fbae-8863-0b92-6d83ddfe5426
