Description Kotresh HR 2021-02-18 13:34:19 UTC 
Description of problem:


A recently introduced change in cephfs.pyx affected the ceph_volume_client evict command. The mds_command() operation expects an argument args to be a string, not a list. Lists are not an encodeable type in Python.

The following trace is observed:
