> Observed that after taking (not restoring) cluster snapshot, but not sure if it's related.
Probably should not be related, but maybe some host was not available due to heartbeat lost,
or something like that. After I closed check dialog and viewed the stack trace at server log,
all pre-upgrade checks become green. So failure seems to be intermittent
