One more issue seen in a scenario, where 'glusterd' is not running and
'glusterfs-events' package is not installed.
I see a traceback in the following scenario :
# gluster pe s
Traceback (most recent call last):
File "/usr/libexec/glusterfs/python/syncdaemon/gsyncd.py", line 29, in
<module>
from syncdutils import FreeObject, norm, grabpidfile, finalize
File "/usr/libexec/glusterfs/python/syncdaemon/syncdutils.py", line 28, in
<module>
from events import eventtypes
ImportError: No module named events
peer status: failed
Connection failed. Please check if gluster daemon is operational.

As a workaround to this, one need to install glusterfs-events package along
with python-gluster package.

RCA:
Geo-rep/Snap scheduler imports eventtypes.py but that file is packaged under
glusterfs-events rpm. During glusterd/gluster cli invocation, call to
`/usr/libexec/glusterfs/gsyncd --version` is failing with Python traceback.
To fix the issue, conditionally enable flag in Geo-rep code if events is not
installed by guarding the import.
EVENTS_ENABLED = True
try:
from events import eventtypes
except ImportError:
EVENTS_ENABLED = False
And check this flag while calling gf_event.

I have raised this bug with the understanding that glusterfs-events package is
required for glusterfs-server package. That is the reason in comment0, I
expected that glusterfs-server package to glusterfs-events.
Later understood the fact that the glusterfs-events will be installed only if
there is a requirement.
So the expected result is that glusterd should start without installing
glusterfs-events package

eventsapi/geo-rep: Geo-rep will not work without eventsapi rpms
If glusterfs-events rpm is not installed, Geo-replication will
fail since it imports eventtypes.
Any call to gsyncd will fail with Import error. Glusterd start
fails since it runs `gsyncd.py --version`
