Description of problem: On CentOS6 base OS, post upgrade of gluster from 3.7.8 to 3.8.1, volfiles are not recreated. During upgrade, glusterd is brought up with "--xlator-option *.upgrade=on -N" parameters to ensure the volfiles are regenerated w.r.t latest bits but that fails as glusterd init () fails from glusterd_check_gsync_present () with a error log saying "0-glusterd: geo-replication module not working as desired". Version-Release number of selected component (if applicable): How reproducible: Always Additional info: As a workaround, post 'yum update' following needs to be done. 1. grep -irns "geo-replication module not working as desired" /var/log/glusterfs/etc-glusterfs-glusterd.vol.log | wc -l If the output is non-zero, then go to step 2 2. Check if glusterd instance is running or not by 'ps aux | grep glusterd', if it is, then stop the glusterd service. 3. glusterd --xlator-option *.upgrade=on -N and then proceed ahead with the rest of the steps as per the upgrade section from installation guide.

COMMIT: http://review.gluster.org/14898 committed in master by Atin Mukherjee (amukherj) ------ commit 1b998788ece8c8b52657e8b9aae65d3279690c5b Author: Kotresh HR <khiremat> Date: Tue Jul 12 00:39:31 2016 +0530 glusterd: Fix gsyncd upgrade issue Problem: gluster upgrade is not generating new volfiles Cause: During upgrade, "glusterd --xlator-option *.upgrade=on -N" is run to generate new volfiles. It is run post 'glusterfs' rpm installation. The above command fails during upgrade if geo-replication is installed. This is because on glusterd start 'gsyncd' binary is called to configure geo-replication related stuff. Since 'glusterfs' rpm is installed prior to 'geo-rep' rpm, the 'gsyncd' binary used to glusterd upgrade command is of old version and hence it fails before generating new volfiles. Solution: Don't call geo-replication configure during upgrade/downgrade. Geo-replication configuration happens during start of glusterd after upgrade.
