- Implement `vitastor-kv rescue` command which dumps all readable blocks from the
database regardless of the tree structure and allows to recover a corrupted database.
- Simplify primary OSD selection - use just PG number instead of the hash. This allows
to distribute primary OSDs more evenly and reach better read speeds.
- Fix vitastor-kv-stress hang on parallel list & reopen.
- Fix CAS writes without immediate_commit. Fix is sufficient for vitastor-kv to
operate correctly in non-immediate_commit pools.
- Fix NFS ACCESS calls for broken inodes (allow root access to them).
- Fix broken vitastor-kv-stress --runtime parameter.
- Fix bad vitastor-kv dump output buffering leading to incorrect JSON in dumps.
- Fix writing garbage from uninitialized memory to the empty space in VitastorKV DB.
- Refactor some code in preparation to the release of the new log-structured metadata store.
- Replace assert(done != expected) error message, probably caused by kernel issues with
zero-copy TCP send, with a more concise error description.
- Daemonize before forking in NFS proxy to fix OSD RDMA support (#107)
- Fix possible PG_INCOMPLETE on node outage when allow_net_split is false
- Fix build under Ubuntu 25.10
- Fix journal_no_same_sector_overwrites mode after optimizing WA (#109)
- Optimize WA - reduce it from 4-5 to 3.x by batching journal writes
- Fix ls-pool showing wrong used % when osds are reweighted (#105)
- Fix vitastor-cli rm sometimes hanging when PGs are down (#99)
- Fix vitastor-cli ls displaying raw used space for all inodes when -p is specified (#101)
- Fix "Cannot set property of undefined" in monitor when deleting pool with live inode op stats (#103)
- Revert vitastor-kv change from 2.2.0 leading to crashes in vitastor-kv-stress (#100)
- Add pg_size change check for XOR pools
- Fix root access to VitastorFS files
- Add IPv6 support to make-etcd
- Fix IPv6 etcd address support in OSD & client library
New features:
- Support UBLK in CSI and make it the default
- Add image tree output: `vitastor-cli ls --tree`
Bug fixes:
- Fix OSDs crashing on localized reads from snapshotted images
- Several NFS fixes from github PR #95
- Fix snapshotted bitmap reads not working in EC pools (fix#92)
- Fix UBLK reporting incorrect device size (1/8 of actual size), report logical_block_size=4096
- Do not repeer when stopping PEER_CONNECTING osd_clients (increase PG peering stability on failover)
- Fix marking PGs as incomplete when peers are unavailable
- Fix FS formatter (mkfs and fsck) error handling in CSI (it didn't report mounting errors)
- Fix removal of block PVC devices not working in CSI
- Do not attempt to free outbound ops in clear_immediate_ops (fix#88)
- Add vitastor-disk prepare --dry-run option
- Add librdmacm-dev to build-deps
- Log has_invalid objects
- Do not warn on incomplete+has_invalid PG states as unexpected
- Fix OSD reweight values between 0 and 1 not working in monitor
- Fix OSD assertion failed: n_subops != sent when all object copies are corrupted
- Install ibverbs-providers in vitastor Docker builds
- Fix#86 - base64_decode on arm64 O_o
- Fix Proxmox 9.0 support (remove some kind of a whitelist added in upstream)
New features:
- Add a new kernel device mounting method: [ublk](https://vitastor.io/docs/usage/ublk.html).
It's the fastest method for random IOPS, and it's on par with VDUSE for linear MB/s.
- Disable io_uring waits being reported as iowait on kernels which support it (6.15+)
- Allow to enforce permissions at the VitastorFS NFS server side
- Add qemu_file_mirror_path option to the config to allow to trick Veeam and make it work
- Speed up CRC32C calculation in OSD by fixing a bug and enabling AVX512 version
- Support QEMU 10
- Support Debian 13 Trixie and Proxmox 9.0
- Remove the dependency on system liburing in package builds (build it statically)
Bug fixes:
- Fix checksums NEVER BEING ENABLED in vitastor-disk prepare, even when explicitly requested :-D
- Use default uid and gid from NFS AUTH_SYS when creating files
- Fix object bitmaps supposedly & possibly being corrupted in some rare cases with EC N+2+
- Avoid multiple inflight overwrites to meta blocks - fixes possible data corruption with
one specific SSD model: Memblaze PBlaze5 910 (github #79)
- Fix a bug in antietcd which was leading to leases sometimes not expiring correctly
- Fix a bug in NFS where ".." entry had its `cookie` equal to 0 instead of 1 (github #78)
- Fix snapshots not being deleted during VM deletion in Proxmox plugin (github #85)
- Fix monitor not filtering OSDs by block size correctly
