Loading dashboard, volumes, bricks causes HTTP 500

[MrApe]

Loading pages other than peers results in a HTTP 500 error:

The CLI shows the following error:

Traceback (most recent call last):
  File "/usr/local/lib/python3.6/dist-packages/cherrypy/_cprequest.py", line 638, in respond

    brick_online = brick_status_data.get("online", False)

Any ideas how to debug this?

We'r running glusterfs version 4.1.5 on Ubuntu 18.04 with python 3.6.9.

Digging a bit into the problem showed, that it might have to do with a stopped volume.

Using the following code to list volumes manually...

from glustercli.cli import volume
volist = volume.vollist()
for vol in volist:
  print(volume.status_detail(vol))

...works for some volumes but then raises an error:

Traceback (most recent call last):
  File "test.py", line 4, in <module>
    print(volume.status_detail(vol))
  File "/usr/local/lib/python3.6/dist-packages/glustercli/cli/volume.py", line 187, in status_detail
    return parse_volume_status(volume_execute_xml(cmd),

I will look into the issue this week. Thanks for reporting.

[MrApe]

Any news here? Can we support somehow?
