Vitaliy Filippov 165c204555 Fix BS_OP_DELETE (the implementation was untested up to this point) 2020-06-02 14:26:01 +03:00
Vitaliy Filippov e6a4b634f8 Fix possible write stall
The stall occurred during fio Q=128 random write tests with low flusher_count (4).
It was caused by flushers being unable to flush the beginning of the journal
because it contained older writes to an object that also had writes in the very end
of the journal, after dirty_start.

Vitaliy Filippov 1733de2db6 Test & fix single-PG primary OSD
- Add support for benchmarking single primary OSD in fio_sec_osd
- Do not wait for the next event in flushers (return resume_0 back)
- Fix flushing of zero-length writes
- Print PG object count when peering
- Print journal free space when starting and when congested

Vitaliy Filippov 2b09710d6f Implement blockstore rollback operation
Rollback operation is required for the primary OSD to kill unstable
object versions in OSD peers so they don't occupy journal space
