Note: This bug is displayed in read-only format because
the product is no longer active in Red Hat Bugzilla.
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.
Cause:
The "mount" command is used to remount file systems with no_barriers, but not all file systems can be remounted.
Consequence:
The remount command can fail and error message can be displayed which may confuse users.
Fix:
The error messages from the mount command were silenced.
Result:
If the file system cannot be remounted with no_barriers, it is silently skipped and no error is displayed.
Description of problem:
/etc/tune-profiles/enterprise-storage/ktune.sh (and probably others) is not able to correctly mount a GFS2 volume mounted twice or more times on the same system with the same journal id.
Version-Release number of selected component (if applicable):
tuned-0.2.19-7.el6.noarch
How reproducible:
Always.
Steps to Reproduce:
1. Configure /dev/<path_to>/<gfs2_volume> to mount to /mnt/a and /mnt/b in /etc/fstab
2. Reboot system
Actual results:
ktune.sh tries to mount /mnt/a and /mnt/b with nobarrier option, which is impossible in the configuration above.
Expected results:
Exclude /mnt/a and /mnt/b from the list of devices that have to be mounted with nobarrier option.

This request was evaluated by Red Hat Product Management for
inclusion in the current release of Red Hat Enterprise Linux.
Because the affected component is not scheduled to be updated
in the current release, Red Hat is unable to address this
request at this time.
Red Hat invites you to ask your support representative to
propose this request, if appropriate, in the next release of
Red Hat Enterprise Linux.

I will just silence the error, because remounting local mounts with nobarrier can pass:
# mount
...
/dev/loop0 on /var/tmp/a type gfs2 (rw)
/dev/loop0 on /var/tmp/b type gfs2 (rw)
# mount -o remount,barrier=0 /var/tmp/a
# mount
...
/dev/loop0 on /var/tmp/a type gfs2 (rw,nobarrier)
/dev/loop0 on /var/tmp/b type gfs2 (rw)
