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.

--- Additional comment from Red Hat Bugzilla Rules Engine on 2015-06-10 08:32:20 EDT ---

This bug is automatically being proposed for Red Hat Gluster Storage 3.1.0 by setting the release flag 'rhgs‑3.1.0' to '?'. 

If this bug should be proposed for a different release, please manually change the proposed release flag.
Comment 1 Milos Malik 2015-06-11 08:33:09 UTC 
The gluster daemon wants to run xfs_db tool. Unfortunately, xfs_db is labeled bin_t instead of fsadm_exec_t, therefore xfs_db process does not run in correct doman.
Comment 2 Milos Malik 2015-06-11 10:52:27 UTC 
If you run following commands before your tests:

# semanage fcontext -a -t fsadm_exec_t /usr/sbin/xfs_db
# restorecon -Rv /usr/sbin

does it help?

Created snapshot with latest policy and could not see avc logs.
