No breaking features, it's 2.0.0 just because it includes S3 and because
there are already too many 1.x releases :).
New features:
- S3 is finally available: https://vitastor.io/docs/installation/s3.html
- node.js addon is now packaged as a Debian package
- Support listing PGs by OSDs in `vitastor-cli ls-pgs`
- Implement offline TRIM support: [vitastor-disk trim](https://vitastor.io/docs/usage/disk.html#trim),
[discard_on_start](https://vitastor.io/docs/config/osd.html#discard_on_start)
- Change used_for_fs pool option to used_for_app
Bug fixes:
- Fix several bugs in the node.js addon (a memory leak, an incorrectly triggered event loop)
- Fix a client crash (vitastor-cli rm) during deletion when writeback is enabled
- Fix PG object count statistics on deletion of non-existing objects
- Fix vitastor-nbd crash when mapping by ID instead of inode name
- Fix a client memory leak with enabled immediate_commit and write-back cache
- Add seccomp=unconfined for vitastor docker OSDs to not break io_uring
- Add udev and systemd to vitastor docker image
- Fix upgrading from pre-0.7.1 (very old) systemd units O_o
- Fix total object count calculation in rm_data
New features:
- Support containerized Vitastor installations: http://vitastor.io/docs/installation/docker.html
- Add new functions to the node.js binding: delete(), get_immediate_commit(), on_ready(),
get_min_io_size(), get_max_atomic_write_size()
- S3 (Zenko Cloudserver with Vitastor support) is coming shortly and will be released separately
Bug fixes:
- Use IP-derived etcd node names in make-etcd
- Set short name of the OSD process to display in `top`
- Fix snap-create without pool_id failing when there are multiple pools
- Several bugs are fixed in the write-back cache, it should now be stable:
- Fix incorrect snapshot reads from dirty write-back cache
- Do not try to repeat pending writebacks on OSD reconnections
- Fix client hangs with multiple SYNCs in the writeback queue
- Fix client hangs do to incorrect calculation of the writeback queue size
- Several improvements for NBD mapping/unmapping:
- Add a workaround for race condition in the Linux kernel NBD driver leading
to vitastor-nbd sometimes breaking a previously mapped device instead of
setting up a new one
- Check if the device is actually mapped in vitastor-nbd unmap
- Fix device name/number validation in vitastor-nbd
- Fix OSD crashes after starting with corrupted metadata - from now it will skip
corrupted metadata entries and heal itself
- Fix scrubbing of misplaced objects and object state recalculation after
vitastor-cli fix - previously, an OSD restart could be required to fix object states
- Make primary OSD distribution more stable by using murmur3 hash instead of the old pseudo-rng
- Fix monitor sometimes racing with itself - do not touch /pool/stats from stats
aggregation if PG recheck is active
- Sort vitastor-cli ls output by name by default
- Update antietcd to 1.1.2
