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
