Release 0.8.9 Stable
2023-05-14 01:25:09 +03:00 | 724 commits to master since this release- The tests are now stable and run in a CI system based on Gitea CI
- The release includes final bug fixes for EC:
- Implement missing EC recovery of allocation bitmap when built with ISA-L
- Fix broken snapshot export with EC (allocation bitmap reads were giving incorrect results previously)
- Also fixed bugs manifesting under heavy load:
- Fix monitor possibly applying incorrect PG history on retries
- Fix monitor incorrectly changing PG count when last_clean_pgs contains less PGs than the new number
- Allow writes to wait for free space again, but now correctly (previously dropped in 0.8.2)
- Fix a rare segfault in client (handle client stop during incoming stream handling in 1 more place)
- Make monitor correctly handle etcd connection errors - it could die instead of connecting to another etcd
- Fix OSD rarely being unable to report PG states after a PG was taken over by another OSD
- Fixed return code for incomplete EC objects (now EIO) and made cluster client retry this error
- Made other small changes for tests: timeouts, nice/ionice for etcd, waiting conditions, NBD device checks and so on

Release 0.8.7 Stable
2023-04-11 02:11:57 +03:00 | 768 commits to master since this releaseThis release includes a bunch of important bugfixes for erasure-coded setups
with disabled immediate_commit. After these fixes, "test_heal" OSD killing test
now passes fine with EC:- Fix cluster write stalls with "Error while doing flush on OSD xx: -16 (Device or resource busy)"
in OSD logs possible in EC setups with disabled immediate_commit by selectively
syncing nonsynced objects on STABILIZE/ROLLBACK (https://github.com/vitalif/vitastor/issues/51) - Fix other EC + disabled immediate_commit problems:
- Fix "opcode=5 retval=-2" errors happening on SYNC retries
- Fix non-working "pagination" during PG dirty object flushing
- Fix write operations not continued correctly after dirty object flushing
- Fix incorrect parity read-modify-write calculation when writing into a lost chunk
- Fix OSDs losing left_on_dead PG state of non-clean PGs and thus not removing junk data in the cluster
- Fix a small memory leak caused by bad indexing of EC recovery matrices
- Fix a rare use-after-free in cluster_client caused by a reenterability issue
- Fix vitastor-cli create command syntax in the CSI driver
- Allow to start OSDs without local store for tests
- Fix memory allocation error in disk_tool_meta for non-standard metadata block sizes
- Fix delete operations received before loading pool metadata crashing OSDs with "null pointer exception"
- Improve "theoretical performance" Russian documentation
New features:
- Implement online configuration update for some parameters. Documentation is coming soon :)

Release 0.8.6 Stable
2023-02-28 11:18:48 +03:00 | 790 commits to master since this releaseImportant fixes:
- Fix possibly incorrect EC parity chunk updates with EC n+k, k > 1 and when
the first parity chunk is missing
Minor fixes and improvements:
- Fix incorrect EC free space statistics in vitastor-cli df output
- Speedup vitastor-cli startup in clusters with RDMA
- Remove unused PG "peered" state (previously used to update PG epoch)
- Use sfdisk with just --json in vitastor-disk (--dump --json isn't needed)
- Allow trailing comma in sfdisk output (fixes sfdisk 2.36 compatibility)
- Slightly improve RDMA send/receive code
- Reduce RDMA memory consumption by default (rdma_max_recv/send = 16/8)
- Use vitastor-cli instead of direct etcd interaction in the CSI driver

Release 0.8.5 Stable
2023-01-25 01:43:49 +03:00 | 806 commits to master since this release- Fix a possible "double free" bug in the client library happening on OSD restart
- Fix a possible write hang on PG history update when only epoch is changed
- Fix incorrect systemd target "local.target" in mon/make-etcd
- Allow "content" option in PVE storage plugin to allow to enable containers
- Build client library without tcmalloc which fixes "attempt to free invalid pointer"
errors when, for example, trying to run QEMU with both Vitastor and Ceph RBD disks

Release 0.8.4 Stable
2023-01-13 23:59:54 +03:00 | 814 commits to master since this releaseNew features:
- Implement QCOW2 image/snapshot export via qemu-img (bdrv_co_block_status in the driver)
- Remove OSDs from PG history during
vitastor-cli rm-osdto preventleft_on_deadPG states after deletion - Add a new recovery_pg_switch setting to mix all PGs during recovery, to almost
fully reduce the probability of ENOSPC during rebalance - Introduce partial ENOSPC ("OSD is full") handling - now ENOSPC doesn't turn
into cascades of crashes - Add migration support to Proxmox VE Vitastor driver
- Track last_clean_pgs on a per-pool basis thus reducing data movement in a cluster
with pools remaining unclean/degraded for a long time
Bug fixes:
- Fix a bug where monitor could generate degraded PGs if one of the hosts had no OSDs
- Fix a bug where monitor could skip PG redistribution with a lot of OSDs in cluster
- Report PG history synchronously on the first write, which improves PG consistency
and availability at the same time, because history now gets reported correctly
and doesn't get reported without the need for it - Fix possible write and recovery stalls which could happen in a cluster with both EC and replicated pools
- Make OSD and monitors sanitize & deduplicate PG history items in etcd
- Fix non-working OSD peer config safety check
- Fix a rare journal flush stall where flushing wasn't activated with full journal, but with empty flush queue
- Fix builds without ISA-L (jerasure-only) crashing with EC N+K, K>=2 due to the lack of 16-byte buffer alignment
- Fix a possible crash for EC N+K, K>=2 when calculating a parity chunk with previous parity chunk missing
- Fix a bug where vitastor-disk purge with suppressed warnings didn't work

Release 0.8.3 Stable
2022-12-27 02:40:55 +03:00 | 847 commits to master since this release- Implement a new "vitastor-disk purge" command to remove OSDs with safety checks
- Implement a new "vitastor-cli rm-osd" command to only remove OSD metadata from etcd
- Fix a bug where the monitor could ignore OSD removal and other /osd/stats key changes
- Fix a bug where garbage could be returned when reading objects being written at the same time
- Fix a rare write stall where journal space could be not reclaimed where there
were no new operations in the flush queue - Fix a rare peering stall caused by a previous long listing operations queues limiting attempt
- Fix total object count statistic in OSD on object creation
- Add missing offset&len into vitastor-disk dump-journal for big_writes, fix JSON format
- Make vitastor-cli print help on missing command
- Make vitastor-cli translate all '-' to '_' in CLI options

- Disable HDD autodetection in non-hybrid mode
- Explicitly warn about a buggy kernels on -EAGAIN in io_uring

- Never try to wait for free space inside blockstore thus stalling OSDs
- Fix a rare crash in osd_peering due to callback ordering
- Fix a rare duplication of ping & op message IDs
- Fix a rare use-after-free during pings
