Vitaliy Filippov 6d307d5391 Ignore "readonly" flag when merging snapshots 2021-09-26 11:32:42 +03:00
Vitaliy Filippov acf637950c Implement layer merge 
A new command merges multiple snapshot/clone layers into one of them,
so merged layers can be deleted after this procedure

Vitaliy Filippov 7d3d696110 Implement object listing with controllable parallelism in cluster_client 2021-07-20 00:19:34 +03:00
Vitaliy Filippov 891250d355 Implement CAS writes 
From now on, reads will return the server-side object version numbers
and writes and deletes will have an additional "version" parameter
which, if set to a non-zero value, will be atomically compared with
the current version of the object plus 1 and the modification will
fail if it doesn't match.

This feature opens the road to correct online flattening of snapshot
layers and other interesting things.

Vitaliy Filippov f8ff39b0ab Rework continue_ops() to remove a CPU hot spot 
This rework increases fio -rw=randread -iodepth=128 result from ~120k to ~180k iops :)

Vitaliy Filippov d749159585 Linked list experiment 
Rework client operation queue from a vector to a linked list.
This is required to rework continue_ops() as its current implementation
consumes ~25% of client process CPU.

Vitaliy Filippov 860ac24762 Add "external" bitmap support to the secondary OSD protocol 2021-04-10 17:44:12 +03:00
Vitaliy Filippov 18c72f4835 Correct reenterability fix (now verified with a test) 
It's rather funny but 0.5.12 has to be re-published again
 2021-04-09 12:10:16 +03:00
Vitaliy Filippov efb3678606 Fix qemu-img broken in 0.5.11 
Caused by the lack of reenterability of the main cluster_client function

Vitaliy Filippov f6d705383a Fix client connection recovery bugs, add dirty_ops limit 2021-04-07 11:06:31 +03:00
Vitaliy Filippov a48e2bbf18 Fix write replay ordering when immediate_commit != all 
Previous implementation didn't respect write ordering and could lead
to corrupted data when restarting writes after an OSD outage

Also rework cluster_client queueing logic and add tests for it to verify the correct behaviour
