Last modified: 2016-03-01 00:28:54 EST
Description of problem: Update the export file of volume, execute refresh-config as this command helps to update the export file of volume on all nodes and update the nfs-ganesha process on all nodes. Version-Release number of selected component (if applicable): glusterfs-3.7.1-8.el6rhs.x86_64 nfs-ganesha-2.2.0-4.el6rhs.x86_64 How reproducible: always Steps to Reproduce: 1. export a volume using the ganesha.enable 2. change export file of the volume for setting root_squash on 3. execute refresh-config from same node Actual results: [root@nfs11 ~]# time bash /usr/libexec/ganesha/ganesha-ha.sh --refresh-config /etc/ganesha/ vol3 export.vol3.conf 100% 503 0.5KB/s 00:00 method return sender=:1.61 -> dest=:1.65 reply_serial=2 export.vol3.conf 100% 503 0.5KB/s 00:00 method return sender=:1.62 -> dest=:1.66 reply_serial=2 export.vol3.conf 100% 503 0.5KB/s 00:00 method return sender=:1.62 -> dest=:1.66 reply_serial=2 method return sender=:1.71 -> dest=:1.75 reply_serial=2 Expected results: dbus messages should not seen on stdout or they should be made more meaningful Additional info:

May be a configuration issue. Request QE to reproduce/provide setup to debug further.
Got the setup from QE. There is an issue with output parsing in ganesha-ha.sh script. Posted the fix upstream for review - http://review.gluster.org/#/c/12439/
included in the 3.1.2 rebase
I think it has failed QA test with the latest 3.1.2 rebase code. Saurabh, could you please confirm?
As per result, # time bash /usr/libexec/ganesha/ganesha-ha.sh --refresh-config /etc/ganesha/ vol0 Refresh-config completed on vm2. Refresh-config completed on vm3. Refresh-config completed on vm4. Success: refresh-config completed.
