Vitaliy Filippov e90bbe6385 Implement OpenStack Cinder driver for Vitastor
It can't delete snapshots yet because Vitastor layer merge isn't
implemented yet. You can only delete volumes with all snapshots.
This will be fixed in the near future.

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.

- RDMA support
- Client performance optimisations (4k randread ~120k -> ~180k on 1 core)
- JSON configuration file (/etc/vitastor/vitastor.conf) support
- Bug fixes
2021-05-02 17:47:43 +03:00
Vitaliy Filippov 9174f188b1 Build packages with libibverbs
For CentOS 7 it also requires newer rdma-core as CentOS 7's native version doesn't have
implicit ODP support. The updated version is already uploaded into the vitastor repo.

Vitaliy Filippov d3978c6d0e Do not print RDMA connection messages when log_level=0
By the way, it's 1 by default in the OSD, so these messages will still be there in OSD logs

Vitaliy Filippov 6a6fd6544d Add RDMA options to the QEMU driver 2021-04-29 11:02:49 +03:00
Vitaliy Filippov 971aa4ae4f Implement RDMA receive with memory copying (send remains zero-copy)
This is the simplest and, as usual, the best implementation :)

100% zero-copy implementation is also possible (see rdma-zerocopy branch),
but it requires to create A LOT of queues (~128 per client) to use QPN as a 'tag'
because of the lack of receive tags and the server may simply run out of queues.
Hardware limit is 262144 on Mellanox ConnectX-4 which amounts to only 2048
'connections' per host. And even with that amount of queues it's still less optimal
than the non-zerocopy one.

In fact, newest hardware like Mellanox ConnectX-5 does have Tag Matching
support, but it's still unsuitable for us because it doesn't support scatter/gather

Vitaliy Filippov 9e6cbc6ebc Negotiate max_sge between RDMA client & server 2021-04-29 02:15:20 +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.
