gstatus fails when unable to get self-heal status

[ChristineTChen]

I'm running gstatus in the latest gluster centos container image.

It seems that the gluster volume heal <VOL> info command is only available for replicate/disperse volumes:

# gluster vol heal gv0 info
Volume gv0 is not of type replicate/disperse
Volume heal failed.

Is it possible to allow gstatus to skip displaying self-heal info if not present (for example I added a replicate volume (gv1), but gstatus will throw an error because of gv0 is a distribute volume type? This currently blocks us from using gstatus at all since the -a, -b and -v flags are all throwing the same error from /gstatus/glusterlib/display_status.py.

When attempting to view the gstatus -a of my cluster, I get the following traceback:

Note: Unable to get self-heal status for one or more volumes
Traceback (most recent call last):
