Vitaliy Filippov aad7792d3f Check for loops in parent inode chains 2021-06-20 00:23:03 +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 72aa2fd819 Make OSD and client read common configuration from /etc/vitastor/vitastor.conf 2021-04-30 01:11:27 +03:00
Vitaliy Filippov ce777319c3 WIP RDMA support 
Basic naive implementation works, but it's highly non-optimal as
RNR retransmissions occur all the time. RDMA expects the receiver
to always have place for incoming WRs...

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 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
 2021-04-08 14:59:20 +03:00
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
