- Implement a storage plugin for Proxmox. Now you can use Vitastor with Proxmox!
- Implement `vitastor-cli df` (pool space usage statistics) command
- Add glob pattern support for `vitastor-cli ls`
- Fix several bugs in other CLI commands (resize, create --parent, modify --readonly)
- Use 512 byte logical block size in QEMU driver by default (and thus don't require to set it in QEMU options)
New features:
- Build Vitastor driver as part of QEMU
- Implement renaming images in CLI (vitastor-cli modify --rename)
- Add vitastor-cli alloc-osd and simple-offsets commands and use them in make-osd,
thus removing the dependency on etcdctl
- Make monitor remove stale deleted inode statistics from etcd automatically
- Implement OSD address selection from a subnet, thus removing the need to specify
OSD addresses in startup scripts explicitly
Bug fixes:
- Fix client failover in case of etcd shutdown or crash (make client survive etcd failures)
- Stick to the last live etcd in OSD and mon to prevent random failures when one of etcds is down
- Fix incorrect copying of data from journal to the data device which could lead to data corruption
- Prefer local etcd IPs in OSD
- Remove the total PG count restriction in optimize_change which was sometimes leading
to inability to redistribute PGs over OSDs
- Fix error response parsing on a failed pg state report
- Fix slow linear writes with RDMA by changing default buffer settings
- Fix possible 'TypeError' in openstack nova when using Vitastor cinder driver
- Fix bugs in vitastor-cli create, ls, rm, modify commands
Patch changes:
- Add a patch for libvirt 7.6
- Add patches for QEMU 6.0 and 6.1
- Fix config file path XML location parsing in libvirt patches
- Replace _ with - in QEMU options
- Fix possible 'TypeError' in openstack nova when using Vitastor cinder driver
- Fix possible crashes of QEMU block driver in case of incorrect options
- Implement CLI commands for listing, viewing I/O statistics, creating,
snapshotting, cloning, resizing and modifying images. All these operations
are covered by 3 commands: ls, create, modify
- Implement an important fix to prior OSD set tracking for PGs. The previous
version had an issue which could lead to data loss due to an OSD with older
copy of the data thinking it has the newest copy
- Fix I/O statistics aggregation in the monitor
- Several minor fixes for Cinder driver
- Fix QEMU driver to be compatible with QEMU 2.x > 2.0
- Fix stalls sometimes possible in configurations without immediate_commit due
to insufficient amount of automatic internal fsync operations
- Add `vita` alias for `vitastor-cli`
- New command-line tool: vitastor-cli
- Implement layer (snapshot/clone) merge and delete
- Remove 'bool' from the C header
- Fix a very rare flusher stall
- More diagnostics now printed for slow ops in the log
- Basic support for OpenStack: Cinder driver, patches for Nova and libvirt
- Add missing "image" and "config_path" QEMU options
- Calculate aggregate per-pool statistics in monitor
- Implement writes with Check-And-Set semantics
- Add a C wrapper library with public header
It can't delete snapshots yet because Vitastor layer merge isn't
implemented yet. You can only delete volumes with all snapshots.
This will be fixed in the near future.
