- 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
When qemu_file_mirror_path is set to "/dir/" in /etc/vitastor/vitastor.conf, QEMU driver
returns "/dir/image_name" as the filename in qemu-img info and in QAPI to trick software
like Veeam which expects file-based access. After that, vitastor-nfs can be mounted to that
directory to make backups work :-)
- Support Ubuntu 24.04 Noble
- Fix clients hanging on online PG count change with in-flight operations
- Fix volume_size_info in PVE VitastorPlugin
- Implement bdrv_refresh_filename for the QEMU driver
- Fix RDMA-CM broken in 2.2.0
- Fix possible "invalid %N$ use detected" OSD crashes
- Fix vitastor-nfs build without RDMA
- Fix docker build by adding the forgotten apt/preferences
- Fix libfio_blockstore.so
- Fix "trigger event loop automatically" API version check in the QEMU driver
- Add Content-Type header for prometheus metrics
- Add a patch for libvirt 11.5
- Fix a bug introduced in 2.2.0 - pg_locks weren't disabled for pools without local_reads
correctly which could lead to inactive pools during various operations
- Fix an old bug where OSDs could send sub-operations to incorrect peer OSDs when their
connections were stopped and reestablished quickly, in 2.2.0 it was usually leading
to "sequencing broken" messages in OSD logs
- Fix debug use_sync_send_recv mode
This is required to prevent disconnected peers from sometimes receiving messages
suited for other peers - stop_client was freeing the operations even though they
were still references in the io_uring requests in progress. This was leading to
OSDs sometimes receiving garbage and "broken sequencing" errors in logs as the
memory was usually already reallocated for other operations
- Fix vitastor-disk purge broken after adding the "OSD is still running" check
- Fix iothreads hanging after adding zero-copy send support
- Fix enabling localized reads online (without restarting OSDs) in the default PG lock mode
New features:
- [Localized read support](https://vitastor.io/docs/config/pool.html#local_reads) for multi-datacenter setups.
- io_uring-based [zero-copy send support](https://vitastor.io/docs/config/network.html#min_zerocopy_send_size) -
read the instruction carefully for optimal performance!
- Improve and speedup data distribution, especially in cases of very large hosts (100 OSD+).
Previously, PG optimization speed depended on the number of OSDs, now it only depends on
the number of failure domains. Distribution over specific OSDs is now also more even and
becomes strictly more even when you increase the number of PGs.
- Add a [very interesting instruction](https://vitastor.io/en/docs/usage/nfs.html#linux-nfs-write-size) to change NFS_MAX_FILE_IO_SIZE
- Check operation sequencing and stop connections when it breaks - should help catch some
very rare RDMA packet loss problems.
- `vitastor-cli rm-osd` now refuses to remove OSDs which are still up and suggests to use `vitastor-disk purge`.
- Allow removal of direntries referring non-existent in VitastorFS.
- Change default vitastor-etcd data dir to /var/lib/etcd/vitastor.
Bug fixes:
- Fix compatibility with ISA-L 2.31+. ⚠️Very important: please upgrade Vitastor before upgrading ISA-L to 2.31+.
- Fix in-memory state cleanup for incomplete PGs.
- Fix monitor crash with non-existent node_placement nodes.
- Slightly speedup `vitastor-kv dump` command by adding output buffering.
- Fix theoretically possible slowdowns in OSD sub-operation failure handling code.
- Fix very rare stack overflows in vitastor-kv.
- Fix a possible crash in VitastorFS during handling of file creation race condition.
- Fix modify-pool -s PG_SIZE which didn't work without --pg_minsize.
- Fix marking peer OSDs as alive on receiving data from them via RDMA - in theory,
the bug could result in instability with RDMA under high load with slow disks.
- Fix a rare OSD crash due to double handle_primary_subop() call.
- Fix latency aggregation in global stats (/vitastor/stats in etcd) - do not sum it.
- Hide "Ran out of journal space" log messages by default.
- Wait for RDMA-CM EVENT_ESTABLISHED after rdma_accept(), handle rdma_accept() before acking the event.
- Fix VitastorFS total & free numbers multiplied by extra 2.
- Fix systemd unit name in make-etcd.
- Do not allow reweight > 1 in vitastor-cli modify-osd.
- Fix docker build.
