--- Comment #1 from Kotresh HR <khiremat at redhat.com> ---
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.
