Vitaliy Filippov 32614c5bc8 Add a test for the last change ("split-brain avoidance", lol) 2021-11-13 22:39:17 +03:00
Vitaliy Filippov aa436027c8 Report pg/history from OSD on every degraded activation
Required to prevent data loss due to activation of an OSD with older data
when PG OSD set change doesn't occur. I.e. fixes the simplest case:
- Run 2 OSDs with 1 PG
- Start writing into the PG
- Stop OSD 2
- Stop OSD 1
- Start OSD 2

After this change the PG will refuse to start after the last step.

Vitaliy Filippov 05db1308aa Fix two potential read/write ordering problems (even though not yet seen in tests)
- Write operations could be 'stabilized' and previous versions could be
  purged from OSDs before the removal of version_override and following
  reads could potentially hit different version in EC pools
- Object was marked clean after completing the delete during recovery, so
  reads could in theory hit a deleted version and return nothing

Vitaliy Filippov 97795ea1b1 Use pg_minsize=2 in the pg_count change test
Also don't check for has_degraded because it's not a bug that objects
are _temporarily_ listed as degraded during PG peering as it's not
required for the new primary to connect to _all_ older peers to start
peering. The test may be improved in the future by temporarily disabling
degraded recovery during it and returning the has_degraded check back.
