Description

Command failed on smithi021 with status 22: 'sudo adjust-ulimits ceph-coverage /home/ubuntu/cephtest/archive/coverage timeout 120 ceph --cluster ceph pg dump --format=json'

/a/sage-2017-08-04_21:14:47-upgrade:jewel-x-wip-jewel-x-distro-basic-smithi/1483285

It's right after the first of three mons is upgraded (the leader).

The problem seems to be that the commands it shares with the quorum does not include the pgmonitor commands that are moving to mgr, so the mixed-version mon cluster doesn't advertise things like 'pg dump' at all.

History

#1 Updated by Greg Farnum over 6 years ago

Do we have a "legacy" command map that matches the pre-luminous ones? I think we just need to use that for the command sharing if so. Otherwise need to build one or do something more complicated to union what it knows about and supports without the manager being involved...
