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 82c1a7ec67 Fix statistics reporting, split inode number into pool & inode 2021-04-10 17:44:12 +03:00
Vitaliy Filippov 2612d3198a Introduce image names and metadata storage in etcd
Each inode has: image name, parent inode number & pool, size and readonly flag

Snapshots are created by switching image name to a different inode number
while using the older inode as parent.

Vitaliy Filippov 435045751d Delete objects only after a SYNC during rebalance in the non-immediate_commit mode
Previously OSDs could commit deletes before writes during recovery or rebalance
in the "lazy fsync" (immediate_commit=off) mode which could result in lost objects

Vitaliy Filippov 0d2efbecc9 Preserve previous PG history when changing PG distribution
Fixes incorrect PG history in case when a new rebalance is started
before the finish of the previous one which could make primary OSDs unable
to locate some objects on some secondaries.
2021-03-11 00:16:10 +03:00
Vitaliy Filippov e62e8b6bae Use real pg configuration instead of the "last clean" one for generating PG history
Basically fixes the bug introduced in 0.5.7 where an rebalance interrupted
by the monitor could result in forgetting objects moved to the new place

Vitaliy Filippov 2a5036669d Fix PG count change procedure
In previous versions PG histories were calculated incorrectly during
PG count change which led to objects being lost on OSDs not in PG's osd set.

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.
