Vitaliy Filippov 340a4b4f27 Release 0.6.16
- Implement `vitastor-cli status` (print cluster status) command
- Add a new `make-osd-hybrid.js` script to quickly prepare a lot of hybrid (HDD+SSD) OSDs
- Implement snapshot deletion for Cinder driver (only works in a healthy cluster)
- Fix a huge :) bug causing reads to return all zeroes during rebalance. Add a test to prevent it in the future
- Disconnect NBD proxy correctly without leaving a zombie [vitastor-nbd] process in D state
- Fix a rare write hang appearing with small write throttling enabled

Vitaliy Filippov 85298ddae2 Release 0.6.15
- Make peering much faster in medium to large clusters
- Fix a reenterability issue which could rarely lead to peering process hangs

Vitaliy Filippov 36f352f06f Release 0.6.13
- Fix client hangs possible on OSD restarts (bug affected versions from 0.5.11)
- Fix "Assertion `sqe != NULL' failed" io_uring-related crashes possible
  on some kernels (0.6.11 increased probability of this bug)
- Fix timeout=0 in NBD proxy
- Fix build under centos 7

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 https://github.com/mirrorll)
- 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 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 2020608a39 Release 0.6.10
- Implement a storage plugin for Proxmox. Now you can use Vitastor with Proxmox!
- Implement `vitastor-cli df` (pool space usage statistics) command
- Add glob pattern support for `vitastor-cli ls`
- Fix several bugs in other CLI commands (resize, create --parent, modify --readonly)
- Use 512 byte logical block size in QEMU driver by default (and thus don't require to set it in QEMU options)

Vitaliy Filippov aa1e21dd99 Release 0.6.9
New features:
- Build Vitastor driver as part of QEMU
- Implement renaming images in CLI (vitastor-cli modify --rename)
- Add vitastor-cli alloc-osd and simple-offsets commands and use them in make-osd,
  thus removing the dependency on etcdctl
- Make monitor remove stale deleted inode statistics from etcd automatically
- Implement OSD address selection from a subnet, thus removing the need to specify
  OSD addresses in startup scripts explicitly

Bug fixes:
- Fix client failover in case of etcd shutdown or crash (make client survive etcd failures)
- Stick to the last live etcd in OSD and mon to prevent random failures when one of etcds is down
- Fix incorrect copying of data from journal to the data device which could lead to data corruption
- Prefer local etcd IPs in OSD
- Remove the total PG count restriction in optimize_change which was sometimes leading
  to inability to redistribute PGs over OSDs
- Fix error response parsing on a failed pg state report
- Fix slow linear writes with RDMA by changing default buffer settings
- Fix possible 'TypeError' in openstack nova when using Vitastor cinder driver
- Fix bugs in vitastor-cli create, ls, rm, modify commands

Patch changes:
- Add a patch for libvirt 7.6
- Add patches for QEMU 6.0 and 6.1
- Fix config file path XML location parsing in libvirt patches
- Replace _ with - in QEMU options
- Fix possible 'TypeError' in openstack nova when using Vitastor cinder driver
- Fix possible crashes of QEMU block driver in case of incorrect options

Vitaliy Filippov 920345f7b6 Release 0.6.8
- Build separate packages for OSD, monitor, client, C header, fio and QEMU drivers
  instead of one package which included everything
2021-11-15 00:49:21 +03:00
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 fb2f7a0d3c Release 0.6.6
- New command-line tool: vitastor-cli
- Implement layer (snapshot/clone) merge and delete
- Remove 'bool' from the C header
- Fix a very rare flusher stall
- More diagnostics now printed for slow ops in the log

Vitaliy Filippov fd8244699b Implement basic CSI driver
