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 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).

Description Prasanth 2015-05-19 09:51:13 UTC

+++ This bug was initially created as a clone of Bug #1220999 +++

Description of problem:
The volume set option uses 'gluster vol set volname ganesha.enable on' sends a DBus signal to export/unexport volume.
When SElinux is enabled, the connection is not established. 

12/05/2015 16:05:21 : epoch 5551d769 : nfs1 : ganesha.nfsd-8462[main] gsh_dbus_pkginit BUS :CRIT bus_bus_get failed (An SELinux policy prevents this sender from sending this message to this recipient (rejected message had sender "(unset)" interface "org.freedesktop.DBus" member "Hello" error name "(unset)" destination "org.freedesktop.DBus"))
12/05/2015 16:05:21 : epoch 5551d769 : nfs1 : ganesha.nfsd-8462[main] gsh_dbus_register_path BUS :CRIT bus_connection_register_object_path called with no DBUS connection

Version-Release number of selected component (if applicable):
glusterfs-3.7.0beta1-0.69.git1a32479.el6.x86_64
nfs-ganesha-2.2.0-0.el6.x86_64
How reproducible:

Steps to Reproduce:
1. create a volume of 6x2 type
2. do nfs-ganesha setup
3. use gluster volume set <volname> ganesha.enable on to export the volume
4. showmount -e localhost

Actual results:
step 4 fails, as volume is not mounted by step 3

issue as mentioned in description section

Expected results:
Selinux should be not a detrrent in exporting a volume

Comment 5 Meghana 2015-05-19 10:12:07 UTC

Oh sorry, that flag also got overwritten. Milos Malik, is there anything else
you would need? The machine has SElinux as permissive right now.

ausearch -m user_avc -i -ts today
<no matches>
