This still doesn't make listings 100% consistent yet; for 100% consistent
listings we have to receive listings only from the primary OSD, not from all
peer OSDs, but this issue will be fixed separately.
New features:
- Implement basic VitastorFS support in [CSI](https://vitastor.io/docs/installation/kubernetes.html)
- Implement [NFS RDMA](https://vitastor.io/docs/usage/nfs.html#rdma) support
- Pause pool rebalance when monitor detects that it can lead to any OSD becoming full ([osd_backfillfull_ratio](https://vitastor.io/docs/config/monitor.html#osd_backfillfull_ratio))
- Auto-select correct [RDMA device and GID](https://vitastor.io/docs/config/network.html#rdma_device) based on osd_network and RoCEv2 priority
- Report slow ops in OSD stats in etcd and show them in vitastor-cli status
Bug fixes:
- Fix possibly incorrect linked list deserialization in NFS
- Fix possible crash in vitastor-nfs --block READDIR operation
- Map netlink after forking to show correct PID in vitastor-nbd ls
- Simplify and fix create-pool OSD count checks for the case of hosts split into sub-nodes
- Make monitor print "Waiting to become master" just once, not every 5s
- Take out_size from oimg if not specified in vitastor-cli dd
- Do not report OSDs with empty statistics as "full" in status
- Trigger double autosync when switching PG state to prevent leaving garbage in non-immediate_commit clusters
- Fix a lack of connection timeout for etcd websockets in OSD leading to slower etcd failover (~70s instead of ~10s)
- Fix a rare OSD crash during client disconnect
- Fix PGs sometimes sticking until OSD restart in the "has_unclean" state with EC pools
- Fix metadata partition zeroing in vitastor-disk prepare
- Add patches for qemu 9.1 and pve-qemu 9.0 and 9.1
- Fix libvirt 8 patch
- Support custom hybrid OSD creation (`vitastor-disk prepare --hybrid --fast-devices /dev/xxx,/dev/yyy`)
- Auto-change partition paths to /dev/disk/by-partuuid/ in `vitastor-disk prepare`
- Allow to select cached I/O in vitastor-disk commands
- Fix multiple bugs in vitastor-disk resize & add tests for them
- Fix vitastor-disk write-meta/write-journal in superblock-based mode writing it to an incorrect device
- Fix vitastor-disk prepare sometimes again not seeing new partitions
- Cleanup PG history and stats of deleted pools
- Fix "is already mounted" checks in CSI
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
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
