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 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 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.
