New features:
- Support resizing normal vitastor-disk partitions and moving journal/metadata: [vitastor-disk resize](https://vitastor.io/docs/usage/disk.html#resize)
- Support simple forms of vitastor-disk {dump,write}-{meta,journal} for OSD partitions
Bug fixes:
- Fix block RWX volumes broken after introducing stage/unstage support
- Do not allow to create non-block RWX volumes in CSI
- Fix vitastor-disk prepare not seeing the newly created partition in rare cases
- Fix non-array tags not showing up in ls-osd/osd-tree
- Make OpenNebula oned.conf patching during installation smarter
- Fix iseek option in vitastor-cli dd not working
- Validate conv=, iflag=, oflag= options in vitastor-cli dd
- Fix vitastor-disk write-meta not writing header checksum to the disk
- Fix JSON format in vitastor-disk dump-meta
- Fix read_chain_bitmap not working for snapshot in another pool
- Fix a possible OSD crash during parallel read & write to an image with snapshots
- Several followups to the READ_CHAIN_BITMAP fix: avoid data reads, fix possible overflow in is_zero(), fix bitmap size
OSDs could crash with the following "assertion failed" message (crash didn't affect data
and was caused by OSD thinking upper blocks are full while they weren't). Reproduction
without introducing artificial delays is hard because you have to force OSD to read an
object with enqueued but not handled write which fills previously non-full bitmap. O_o.
```
vitastor-osd: ./src/osd/osd_primary_chain.cpp:613: void osd_t::send_chained_read_results(pg_t&, osd_op_t*): Assertion `stripes[role].read_buf' failed.
```
Hotfixes for OpenNebula and upgrade hotfix for 1.7
- Fix deploy.vitastor, save.vitastor, restore.vitastor scripts not working for nodes other than master oned
- Fix deploy.vitastor not working for VMs without Vitastor disks
- Disable clearing old PG configuration when upgrading from 1.7 or older versions (it was breaking old clients)
Bugfix release, would be 1.7.2, but etcd layout changes mandate it to be 1.8.0. :-)
- Change etcd layout: /config/pgs is now /pg/config, /pg/stats/* is now /pgstats/*.
This is required to fix a rare PG history tracking issue caused by non-atomic
delivery of etcd events sometimes resulting in `incomplete` objects in EC pools
after mass OSD restarts. Upgrading can be performed freely, downgrade requires
additional action: [1.8.0 to 1.7.1](https://git.yourcmc.ru/vitalif/vitastor/src/branch/master/docs/usage/admin.en.md#1-8-0-to-1-7-1)
- Fix a rare client hang on PG primary OSD switch
- Fix vitastor-nfs started using mount command sometimes not stopping automatically after unmount
- Fix vitastor-nfs mounts started using mount command sometimes hanging after daemonizing
- Fix merge/flatten into a pool with different object size (image migration between pools case)
- Do not print extra "PG disappeared after reload" verbose log messages for non-existing PGs
- Fix clustered Antietcd support and persistence filter
- Do not try to purge the same OSD multiple times if its multiple devices are passed to purge
- Various node.js binding fixes
