The "missing primary copy" message happens on a mixed luminous/mimic cluster (MONs, MGR, and half of OSDs running mimic, other half of OSDs running luminous) in the third or fourth iteration of radosbench within "stress-tasks", right after a bluestore "bad crc32c/0x10000 checksum" message.

Here is the immediately preceding cluster health status:

Also, I noticed this in the test yaml:

  - parallel:
    - stress-tasks
  - install.upgrade:
      client.0: null
      osd.4: null
  - ceph.restart:
      daemons:
      - osd.4
      - osd.5
      - osd.6
      - osd.7
      wait-for-healthy: false
      wait-for-osds-up: true

The only thing within parallel is "stress-tasks". Shouldn't the "install.upgrade" and "ceph.restart" stanzas be included under parallel, as well?

The test in its current form seems to do: (1) upgrade all MONs, MGRs, and half of the OSDs to mimic, (2) stress this "split luminous/mimic" cluster, (3) upgrade the remaining OSDs to mimic.

It does not appear to thrash or otherwise stress the cluster during the upgrade process.

That's by design. The intent is to stress a mixed-version cluster with thrashing. The parallel tests do the upgrade and stress workload in parallel.

Updated by Sage Weil over 5 years ago

  • Subject changed from "[ERR] : 14.8 missing primary copy of .." in upgrade:luminous-x-mimic to bad csum during upgrade test
  • Status changed from New to Need More Info
  • Assignee deleted (Sage Weil)
  • Priority changed from Urgent to High

Looking at the log, I don't see any useful clues as to what might have went wrong. No intervening writes, etc.
