Vitaliy Filippov f3ce166064 Do not print nan% in df when a pool has no available OSDs 2022-01-31 18:23:57 +03:00
Vitaliy Filippov 717d303370 Handle get_sqe failures, don't die with "will fall out of sync" in epoll_manager
Problem is that in recent kernels io_uring may return completions BEFORE
clearing the submission queue. I.e. for example its capacity is 512, there
were 512 requests, one of them completed, so when the request completion is
processed the queue "should have" 1 free slot. But sometimes it doesn't because
io_uring doesn't always clear the submission queue before sending CQE :-/

Vitaliy Filippov d9857a5340 Check for SQEs, not for completions
Should finally fix Assertion `sqe != NULL' failed introduced after journaling
refactor in 0.6.11...

Vitaliy Filippov 4047ca606f Add missing cancel_op(currently being read op) when stopping a client
Fixes client hangs possible after stopping & restarting an osd.
Hangs happened when a connection was closed in the middle of reading a READ
operation reply from the network. In this case the operation being read was
in read_op and the client didn't free it when closing the connection.

Test case for msgr_read.cpp:
- Partially read reply for a READ operation
- stop_client()
- Check that the READ operation returns EPIPE

The bug was actually introduced in 0.5.11.

Vitaliy Filippov c1929cabe0 Release 0.6.12
etcd connection stability, clang & elbrus support

- Fix build under CLang and Elbrus LCC compilers, making Vitastor compatible
  with Elbrus CPUs :)
- Completely fix the bug where OSDs didn't connect to peers and incorrectly marked
  PGs as incomplete
- Limit I/O depth for deletes the same way as for small writes. Makes OSD crashes
  with "Assertion failed: sqe != NULL" during image deletion go away
- Fix a very old, but rare, journaling bug (credits to
- Fix flushing of unclean journaled objects leading to OSDs sometimes hanging
  after failover in EC setups (bug was introduced in 0.6.7)
- Fix several problems that could prevent smooth operation of a Vitastor cluster
  under the condition of partial etcd failure:
  - OSDs could randomly fail due to too strict error handling
  - New clients and OSDs could be unable to start because of the lack of retries
  - CLI could fail some commands because of the lack of retries
  - Monitor could stop receiving state updates because of the lack of websocket pings
- Fix monitor being unable to rebalance PGs after a downscale of pool pg_size (3->2)
- Exit with failure when trying to nbd map or benchmark a non-existing image
- Use HTTP keep-alive for etcd connections
- Allow to configure etcd request timeouts and retries
- Allow to configure NBD timeout, max devices and partitions, and set default to
  up to 64 devices with up to 3 partitions each

Vitaliy Filippov cc6b24e03a Allow to configure NBD timeout, max devices and partitions
Also set default NBD devices/partitions to 64/3, Linux default is 16/16 which is way too low

Vitaliy Filippov 8dc1ffb13b Try to connect with PG peers before deciding it's incomplete :)
I already attempted to fix it in 0.6.11, but it happened so that the fix was
only partial :)

Vitaliy Filippov 7bdd92ca4f Fix build under clang and some warnings
Build problems fixed:
- void* pointer arithmetic which is a GNU extension (works as byte*)
- "variable size object may not be initialized" which is OK under GCC
- nullptr_t related error in json11 (it lacks 'operator <' in clang)

Warnings fixed:
- empty nested struct initializer { 0 } replaced by {}
- removed several unused lambda captures

Vitaliy Filippov b9f5c2a823 Support zero-copy send in fio_sec_osd to allow testing it
Prelimilary results:
- CPU usage drops significantly. For example, in T1Q8 128K write test against
  stub_uring_osd with 10G network and Athlon X4 860k CPU it drops from 100% to 30%
- Latency becomes slightly worse. In T1Q1 4K write test in the same environment
  latency increases from 56 to 63 us.
- Small write throughput also becomes slightly worse. In T1Q128 4K write test
  against stub iops decreases from 138k to ~110k (unstable, fluctuates 100k..120k).
  Note that this is without io_uring, of course.

Vitaliy Filippov 0785bdf8b3 Release 0.6.11
- Slightly reduce journaling write amplification (requires no_same_sector_overwrites=false)
- Fix listen_backlog (it was 0) because it could more than halve OSD socket send speed
- Support IPv6 OSD addresses
- Do not try to initialize client in simple-offsets
- Fix OSDs sometimes marking PGs incomplete instead of trying to connect with peers
- Allow to configure OSD placement in node_placement
- Allow to run with 4k sector size block devices. Natural, but it was forbidden

Vitaliy Filippov f93491bc6c Implement journal write batching and slightly refactor journal writes
Slightly reduces WA. For example, in 4K T1Q128 replicated randwrite tests
WA is reduced from ~3.6 to ~3.1, in T1Q64 from ~3.8 to ~3.4.

Only effective without no_same_sector_overwrites.
