New features:
- Support handling TCP I/O in simple separate io_uring-based I/O threads - may increase linear performance to 7-8 GB/s
- Experimental internal etcd replacement - antietcd
- Monitor now has a built-in Prometheus exporter
- Added a reference Grafana dashboard
- Implement vitastor-cli osd-tree and ls-osd commands
- Implement vitastor-cli modify-osd command
- Implement vitastor-cli pg-list command
- Implement VitastorFS defragmentation
- Implement basic node.js binding (not published on npm yet)
Changes:
- Make immediate_commit=all the default everywhere to match default vitastor-disk behaviour
- Make pool-create error message more obvious and add details to it
- Set default etcd_ws_keepalive_interval to 5 seconds (speedup client etcd failover)
- Support OpenStack 2023.2 in Nova and Cinder drivers/patches
- Add patches for libvirt 10.x
- Add patches for QEMU 8.2 and 9.0
- Implement internal restart / run_forever in monitor
- Some source tree refactoring - sources are now moved into subdirectories, monitor is now split into multiple files
- Add vitastor_c_inode_get_immediate_commit in vitastor_c client library
- Make vitastor_kv.h header public
Bug fixes:
- Fix total statistics usec/count/bytes not being reported when delta (bps/iops/lat) is zero
- Prevent infinite loop in NFS on files with incorrect metadata pointing to an empty volume
- Fix READDIR offsets (cookies) in VitastorFS sometimes leading to client infinite loops when reading a directory
- Fix a rare infinite loop during OSD journal flushing (OSD hanging and eating 100 % CPU)
- Fix several bugs which could lead to lost writes in setups without immediate_commit:
- Client library treated writes as completed before actually completing them, thus missing them in a subsequent fsync
- Client library didn't repeat writes on the new PG primary when it changed
- OSDs didn't drop peer connections with dirty writes when stopping PG
- Fix Block Pseudo-FS initialization leading to ENOENTs some time after start
- Fix vitastor-cli merge-based commands (merge/flatten/rm snapshot) slowing down and finally failing when using CAS optimistic locks
- Fix pool create/modify --block_size validation
- Fix TTL comparison for determining failed lease/keepalive requests in OSD
- Add support for size suffixes in pool-create --block_size and --immediate_commit values
