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.

- Don't always reconstruct coding chunks
- Reconstruct chunks one-by-one, without overlapping ranges

Vitaliy Filippov 44656fbf67 Allow writes with low version numbers after a delete 2020-12-04 11:54:41 +03:00
Vitaliy Filippov 089f138e0c Allow situations where the journal contains a big_write(v1) after delete(v2) and v1 < v2 
Fixes a crash in the following scenario:
- client issues a delete request (object version is at least 2)
- OSD has time to flush it to the metadata, but doesn't have time to move the journal start pointer on disk
- client overwrites the same object and it gets the version number 1 again
- OSD is restarted and sees delete(v=2), big_write(v=1) in the journal
- dirty_db sequence gets broken and OSD crashes with assert("Writes and deletes shouldn't happen at the same time")

Vitaliy Filippov faa5e1436f Attempt journal trim even without new flushes 
This is the new guaranteed unblocking method which replaces old trims
in init and rollback, and also fixes a possible stall when just several
writes in the beginning of the journal are flushed without triggering
a subsequent trim.
 2020-10-24 01:28:47 +03:00
Vitaliy Filippov 5fbe36198a Fix journal trimming 
1) Update journal's used_start in memory only after updating journal superblock.
Doing the opposite is incorrect because part of the journal will be lost if writers
overwrite its old beginning.

2) Sync journal device after updating the superblock.

3) Do not trim in rollback and init because trimming there would also require
updating the superblock. And the only reason to trim in both those places was
to unblock writers. And a guaranteed unblocking method will follow in the next
commit :)
