Vitaliy Filippov 36c935ace6 Use std::vector for the blockstore submission queue 2021-03-08 17:04:10 +03:00
Vitaliy Filippov 0d8b5e2ef9 Remove unused enqueue_op_first() 2021-03-08 17:04:10 +03:00
Vitaliy Filippov 98f1e2c277 Rework write/sync ordering
Make syncs wait for all previous writes because it's the only way
to make sure that OSDs do not receive incomplete writes in LIST results
during peering when some writes are still in progress.

Also simplify blockstore submission queue logic.

Vitaliy Filippov 09b3e4e789 Fix OSDs being unable to stop PGs that are 'peering', not 'active'
This was sometimes leading to incorrect misplaced and degraded object count statistics

Vitaliy Filippov 07912fd670 Use history/last_clean_pgs to avoid extra data move when observing a series of changes in the cluster 2021-03-08 17:04:10 +03:00

Vitaliy Filippov 29d8ac8b1b Do not report statistics for the empty operation 2021-03-01 16:20:57 +03:00
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.

Vitaliy Filippov 08d4bef419 Fix PG optimizer removing PGs without adding new ones
This happened when the distribution was already valid for the current OSD tree,
but didn't use all OSDs. For example, OSDs 1 2 3 and all PGs equal to [ 1, 2 ]
remained unchanged.

Vitaliy Filippov 4a2dcf7b6b Update the license to VNPL 1.1
VNPL 1.1 is slightly reworded to make it clear that proprietary software
interacting with Vitastor and providing some kind of service to end users isn't
a "Proxy Program" if it's not specially designed to be used with Vitastor.

For example, Windows OS running in a virtual machine stored in a Vitastor
cluster clearly isn't.

Vitaliy Filippov 2d9f09dcb6 Attempt forced trim when stopping an overrun flusher
Fixes a rare hang happening in the event of journal space running out without
new work to do for flushers except the current sector.
The hang could be reproduced more or less consistently with very slow drives.
