Vitaliy Filippov 1f6c4c79d6 vmsplice+splice experiment in stub_osd to test it too 2021-11-22 01:20:12 +03:00
Vitaliy Filippov 4936c42132 Splice via io_uring - bad result too
40% CPU according to perf is lost inside do_splice() -> unix_stream_sendpage()
without io_uring and in various exc_page_fault() with io_uring

Vitaliy Filippov 6c3248a36c Experiment: vmsplice+splice "zero-copy" read in NBD 2021-11-22 00:12:39 +03:00
Vitaliy Filippov a863013cb2 Add a patch for qemu 6.1 and replace _ with - in qemu options 2021-11-21 16:16:46 +03:00
Vitaliy Filippov 660c3f7b0d Change default RDMA settings to 128x 129K buffers
129K to leave extra space for the header

The problem with 8x 1M buffers is that the following happens with,
for example, 2 OSDs and 4M T1Q1 write:
- Server posts 8 receives
- Client posts 8 sends
- WRs are processed by the RDMA stack, but the OSD doesn't have the time
  to handle them and doesn't refill buffers
- Client posts 1 more send
- RNR retransmission happens and performance drops to zero

Overall it seems that RDMA support should be reworked to use real 'RDMA'
operations i.e. operations writing into remote memory. This has an
additional advantage of avoiding a copy at the receive side of the OSD.

Vitaliy Filippov 7eabc364bf Release 0.6.7
- Implement CLI commands for listing, viewing I/O statistics, creating,
  snapshotting, cloning, resizing and modifying images. All these operations
  are covered by 3 commands: ls, create, modify
- Implement an important fix to prior OSD set tracking for PGs. The previous
  version had an issue which could lead to data loss due to an OSD with older
  copy of the data thinking it has the newest copy
- Fix I/O statistics aggregation in the monitor
- Several minor fixes for Cinder driver
- Fix QEMU driver to be compatible with QEMU 2.x > 2.0
- Fix stalls sometimes possible in configurations without immediate_commit due
  to insufficient amount of automatic internal fsync operations
- Add `vita` alias for `vitastor-cli`

Vitaliy Filippov aa436027c8 Report pg/history from OSD on every degraded activation
Required to prevent data loss due to activation of an OSD with older data
when PG OSD set change doesn't occur. I.e. fixes the simplest case:
- Run 2 OSDs with 1 PG
- Start writing into the PG
- Stop OSD 2
- Stop OSD 1
- Start OSD 2

After this change the PG will refuse to start after the last step.
