Hotfixes for OpenNebula and upgrade hotfix for 1.7
- Fix deploy.vitastor, save.vitastor, restore.vitastor scripts not working for nodes other than master oned
- Fix deploy.vitastor not working for VMs without Vitastor disks
- Disable clearing old PG configuration when upgrading from 1.7 or older versions (it was breaking old clients)
Bugfix release, would be 1.7.2, but etcd layout changes mandate it to be 1.8.0. :-)
- Change etcd layout: /config/pgs is now /pg/config, /pg/stats/* is now /pgstats/*.
This is required to fix a rare PG history tracking issue caused by non-atomic
delivery of etcd events sometimes resulting in `incomplete` objects in EC pools
after mass OSD restarts. Upgrading can be performed freely, downgrade requires
additional action: [1.8.0 to 1.7.1](https://git.yourcmc.ru/vitalif/vitastor/src/branch/master/docs/usage/admin.en.md#1-8-0-to-1-7-1)
- Fix a rare client hang on PG primary OSD switch
- Fix vitastor-nfs started using mount command sometimes not stopping automatically after unmount
- Fix vitastor-nfs mounts started using mount command sometimes hanging after daemonizing
- Fix merge/flatten into a pool with different object size (image migration between pools case)
- Do not print extra "PG disappeared after reload" verbose log messages for non-existing PGs
- Fix clustered Antietcd support and persistence filter
- Do not try to purge the same OSD multiple times if its multiple devices are passed to purge
- Various node.js binding fixes
A bunch of monitor fixes
- Add noout flag for OSDs (/vitastor/config/osd/xx)
- Fix "effective" size of degraded PGs (and thus "used space") calculation in monitor
- Fix monitor not clearing PGs of deleted pools
- Fix incorrect PG generation with hosts with 0 OSDs
- Fix monitor crashing during primary OSD recheck when pool has no PGs
- Fix monitor crashing when node_placement included non-existing OSDs
- Fix possible data movement after removing OSDs reweighted to 0
- Remove extra empty keys from pool configurations created by vitastor-cli create-pool
- Fix 32-bit build
New features:
- Implement "hierarchical failure domains" and other complex distribution rules, for example
EC 4+2 over 3 DC, with 2 chunks per each DC ([documentation](docs/config/pool.en.md#level_placement))
- Make OSDs handle ENOSPC - now cluster stays online even if some OSDs fill up
to 100 %, only writes requiring free space hang
- Implement Stage/Unstage & volume locking for CSI to prevent parallel mounting
and/or modifications of the same volume
- Warn about full and almost full OSDs in vitastor-cli status
- Add an experimental NBD netlink map mode as an option ([documentation](docs/usage/nbd.en.md))
- Add --pg parameter to vitastor-cli describe, print objects with 0x in human-readable format too
- Add [administration docs](docs/usage/admin.en.md)
Bug fixes:
- Fix client operation retry timeout - previously the timeout wasn't applied and writes were
retries almost instantly
- Fix monitors crashing on invalid pool configurations
- Fix journaling - make each journal write wait for all previous journal writes
- Fix monitor thinking that OSD weight is 0 after deleting /osd/config/ key online
- Fix a write stall caused by flusher possibly not trimming journal on rollback
- Set 32k csum_block_size for HDD by default in vitastor-disk
After half a year of hard work, VitastorFS is finally here ! :-)
New features:
- VitastorFS, a full-featured clustered (read-write-many) file system.
Documentation: [VitastorFS](docs/usage/nfs.en.md)
- Embedded key-value database implementation based on Parallel Optimistic B-Tree
algorithm and used for the metadata of VitastorFS
- Pool management commands in vitastor-cli (create-pool, list-pools, rm-pool, modify-pool).
Thanks MIND Software (https://mindsw.io) for their contribution!
[Documentation](docs/usage/cli.en.md#create-pool)
Bug fixes:
- Fix a very rare "infinite loop" in the client library
- Fix a rare OSD hang on during start when zeroing out bad metadata entries left from the previous run
- Do not use \r if output is not a terminal (should fix unexpected job output in proxmox)
- Fix rm/rm-data error return code, add --down-ok option to bypass the error
- Add EIO retry timeout and allow to disable these retries, rename up_wait_retry_interval to client_retry_interval
- Add ubuntu jammy build
- Wait for blockstore initialisation before starting OSD (prevent timeouts when init takes time)
- Fix a rare use-after-free in automatic sync after delete in blockstore
- Fix another old "BUG: Attempt to overwrite used offset" in a very simple
case: bs=4k rw=write iodepth=16 from OSD start; add this case to tests
- Fix a rare crash with "unexpected state during flush: 0x51" possible with
EC since 1.4.2 during rebalance and OSD outages
- Fix a rare write stall with EC & immediate_commit=none caused by sync
operations reserving unneeded space in the journal
- Fix 32-bit build warnings, most in printf/scanf format strings
Unwavering stabilization of 1.4.x, continued :-)
- Include the accidentally lost part of 1.4.5 journal trimming fix
- Fix a possible OSD crash with "BUG: Attempt to overwrite used offset"
which was probably present for long time, but became apparent after
fixing flapping tests in CI
- Fix remaining flapping tests in CI. It was the first time when tests
actually passed without retries :-)
- Fix a write stall caused by incorrect journal trimming introduced in 1.4.4 :)
- Fix PGs sometimes hanging in "starting" state on mass OSD restarts
- Fix a rare crash with "map::at" during OSD pings
- Use new defaults for non-capacitor (desktop) SSDs - improves T1Q256 random write from ~6k iops to ~45k iops
- Make journal_trim_interval configurable
A couple of fixes for EC pools
- Fix a segfault possible on partial EC overwrite in 1234 -> 5030 rebalance scenario
- Fix two problems leading to EC pools stalling on rebalance & parallel sudden stops
of OSDs, for example during a sudden poweroff of a host:
- Recovery auto-tuning (1.4.0 feature) could apply too large delays and stall
the EC journal - fixed by limiting delays with a new recovery_tune_sleep_cutoff_us
parameter (10 seconds by default) and applying recovery pauses before write
operations, not after them, to not occupy space in the journal for long time
- Dynamic journal space reservation (1.3.0 feature) wasn't accounting new writes
when checking the limit so OSDs could still fill the journal fully and stall -
fixed by including new writes into the limit
- Print etcd dbSize instead of dbSizeInUse in status
Hotfix for hotfix O:-)
- "Write stall fix" was incomplete and EC write stalls could
continue even on 1.4.2. Now they're finally fixed O:-)
- Make monitor ignore statistics of stopped OSDs. Previously if you stopped all
OSDs the last total I/O numbers would remain the same indefinitely
- Log to systemd by default
- Fix excessive autosyncs after every operation with disabled immediate_commit (introduced in 1.1.0)
- Fix a possible write stall with EC due to the lack of OSD wakeup after stabilizing previous writes
- Change sync operation semantics as a final fix to possible write stalls with EC and disabled immediate_commit
- Sync after deleting data in CLI rm / rm-data if immediate_commit is disabled
- Fix OSDs ignoring syncs & autosyncs for delete operations
- Fix OSD space reporting sometimes adding garbage zeros for deleted inodes (causing extra pool/stats etcd keys for deleted pools)
- Speed up monitor failover - change default etcd_mon_ttl from 30 to 5 seconds
- Speed up operation retries - change default up_wait_retry_interval to 50 ms
- Add patch for libvirt 9.10
- Fix a monitor crash on primary OSD switching introduced in 1.4.0
- Fix "partly outside array bounds" warnings for GCC 12 in cpp-btree
- Fix a realloc memory leak in theory possible with too large listings (OSD_OP_LIST)

- Auto-restoration of dead VDUSE daemons in CSI plugin
- Add vitastor-disk update-sb command
- Update QEMU for Debian Bookworm to 8.1 and use it for CSI plugin
Bug fixes:
- Fix pools SOMETIMES staying inactive after stopping a node due to OSDs not reacting
to PG state changes caused by incorrect full reload of state from etcd on reconnection
- Make monitors retry pool configuration changes quickier which fixes them being unable
to apply changes when an ongoing rebalance is quickly making a lot of PGs clean
- Fix CSI plugin not accepting array of strings as etcd address in /etc/vitastor/vitastor.conf
- Allow multiple interfaces with the same IP address, for "simple routed" full mesh network

New features:
- RDMA without ODP - much faster and all cards are now supported, not just Mellanox
- VDUSE in CSI - faster, more stable and can even recover after CSI pod restart!
- Reserve journal space for stabilize requests dynamically to prevent stalls under load with EC
- Raise default NBD timeout from 30 to 300 seconds and allow to take it from /etc/vitastor/vitastor.conf
- Remove explicit etcdUrl/etcdPrefix K8S storage class parameter support to prevent
etcd migration issues for volumes created with these parameters
- Support QEMU 8.1 and pve-qemu 8.1
Bug fixes:
- Fix RDMA connection (and thus memory) leak
- Fix rare crashes under load due to incorrect io_uring queue size tracking
- Fix monitor statistics aggregation in case of empty /osd/stats keys

New features:
- Implement CSI volume expansion
- Implement CSI volume snapshots

Bug fixes:
- Important bug fix for EC: fix EC n+k, k>=2 read recovery in ISA-L version returning
incorrect data when reading at least the second chunk out of multiple missing chunks
without reading the first one. All users of EC n+k, k>=2 should upgrade as soon as
possible, and upgrade should be conducted with downtime: first stop all clients
(VMs/containers), then all OSDs, then upgrade and restart everything.
- Fix unstable statistics aggregation in monitor (affecting vitastor-cli status and df)
- Make udev not wait for OSDs to start during boot
- Do not report negative numbers of offline PGs in vitastor-cli status when changing PG count
- Report both old and new PG counts in vitastor-cli df when changing it
- Fix OSDs sometimes not starting with "The code only supports journal versions 1 and 2,
but it is 2 on disk" error after upgrading from pre-1.0 versions and letting OSDs run
for some time
- Fix monitors sometimes returning old PG count back after OSD configuration changes
- Make monitor PG changes more stable and timeout errors less probable
New features:
- Implement [client writeback cache](docs/config/client.en.md#client_enable_writeback)
- Add the third I/O mode: [O_DIRECT|O_SYNC](docs/config/osd.en.md#data_io) (good for Optane)
- Reduce load on etcd by splitting OSD lease and statistics reporting intervals:
[etcd_stats_interval](docs/config/osd.en.md#etcd_stats_interval) (default 30 sec)
- Make MON automatically filter OSDs by layout (block_size/immediate_commit/bitmap_granularity)
to prevent "refusing to start PGs of this pool" errors on misconfiguration
- Support running fio benchmarks on systems without io_uring
- Make QEMU driver compatible with QEMU 8.1
- Document usage of [vhost-user-blk](docs/usage/qemu.en.md#vhost-user-blk)

probably lead to incorrect writes in rare cases)
- Fix rare OSD crash during sync operation processing
- Fix a reenterability issue in cluster_client not reproducible in QEMU/fio,
but reproducible with the currently developed K/V database implementation
- Fix deletion of the first modified object - OSDs could crash if you modified
the same object a lot of times, then deleted it, and then modified it again
- Fix the fio_sec_osd test tool
