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
