- Add ISA-L erasure code implementation, now used automatically instead of jerasure when available
- Fix listings sending too many parallel requests to OSDs
- Fix rm-data crashing with --wait-list
- Remove empty inodes from statistics and `ls` output, after <inode_vanish_time> seconds after deletion
- Make monitor delete pool statistics when the pool is deleted and thus remove them from `df` output
- Log multiple etcd addresses in OSD logs correctly
- Fix true/false parsing in json configs like no_recovery/no_rebalance
- Show no_recovery, no_rebalance, readonly flags in status
- Add documentation! :-) in Russian and English
- Implement an NFS proxy for file-based access emulation to Vitastor
images for non-QEMU based hypervisors like VMWare, as a better way
than iSCSI
- Implement "primary affinity tags"
- Add a patch for libvirt 6.0
- Fix free_down_raw in cli status
- Fix a rare bug where OSDs could drop unrelated connections on errors
- Fix incorrect reading of extra metadata block leading to extra unknown objects in stats
- Fix CSI driver volumeMode: Block support
- Add block PVC and pod examples
- Fix build under 32 bit architectures
- Fix slow connection ramp-up caused by up_wait_retry_interval
- Implement `vitastor-cli status` (print cluster status) command
- Add a new `make-osd-hybrid.js` script to quickly prepare a lot of hybrid (HDD+SSD) OSDs
- Implement snapshot deletion for Cinder driver (only works in a healthy cluster)
- Fix a huge :) bug causing reads to return all zeroes during rebalance. Add a test to prevent it in the future
- Disconnect NBD proxy correctly without leaving a zombie [vitastor-nbd] process in D state
- Fix a rare write hang appearing with small write throttling enabled
- Fix IPv6 address parsing
- Fix "cannot read bytes of undefined" in the monitor on a fresh DB
- Fix possible hangs of read requests on OSD restarts without immediate_commit=all mode
- Fix OSDs skipping misplaced recovery in some cases
- Fix OSDs possibly dying with "map::at" errors when other OSDs are stopped
- Fix division by zero in ls if all pool OSDs are down
- Fix client hangs possible on OSD restarts (bug affected versions from 0.5.11)
- Fix "Assertion `sqe != NULL' failed" io_uring-related crashes possible
on some kernels (0.6.11 increased probability of this bug)
- Fix timeout=0 in NBD proxy
- Fix build under centos 7
etcd connection stability, clang & elbrus support
- Fix build under CLang and Elbrus LCC compilers, making Vitastor compatible
with Elbrus CPUs :)
- Completely fix the bug where OSDs didn't connect to peers and incorrectly marked
PGs as incomplete
- Limit I/O depth for deletes the same way as for small writes. Makes OSD crashes
with "Assertion failed: sqe != NULL" during image deletion go away
- Fix a very old, but rare, journaling bug (credits to https://github.com/mirrorll)
- Fix flushing of unclean journaled objects leading to OSDs sometimes hanging
after failover in EC setups (bug was introduced in 0.6.7)
- Fix several problems that could prevent smooth operation of a Vitastor cluster
under the condition of partial etcd failure:
- OSDs could randomly fail due to too strict error handling
- New clients and OSDs could be unable to start because of the lack of retries
- CLI could fail some commands because of the lack of retries
- Monitor could stop receiving state updates because of the lack of websocket pings
- Fix monitor being unable to rebalance PGs after a downscale of pool pg_size (3->2)
- Exit with failure when trying to nbd map or benchmark a non-existing image
- Use HTTP keep-alive for etcd connections
- Allow to configure etcd request timeouts and retries
- Allow to configure NBD timeout, max devices and partitions, and set default to
up to 64 devices with up to 3 partitions each
- Slightly reduce journaling write amplification (requires no_same_sector_overwrites=false)
- Fix listen_backlog (it was 0) because it could more than halve OSD socket send speed
- Support IPv6 OSD addresses
- Do not try to initialize client in simple-offsets
- Fix OSDs sometimes marking PGs incomplete instead of trying to connect with peers
- Allow to configure OSD placement in node_placement
- Allow to run with 4k sector size block devices. Natural, but it was forbidden
- Implement a storage plugin for Proxmox. Now you can use Vitastor with Proxmox!
- Implement `vitastor-cli df` (pool space usage statistics) command
- Add glob pattern support for `vitastor-cli ls`
- Fix several bugs in other CLI commands (resize, create --parent, modify --readonly)
- Use 512 byte logical block size in QEMU driver by default (and thus don't require to set it in QEMU options)
New features:
- Build Vitastor driver as part of QEMU
- Implement renaming images in CLI (vitastor-cli modify --rename)
- Add vitastor-cli alloc-osd and simple-offsets commands and use them in make-osd,
thus removing the dependency on etcdctl
- Make monitor remove stale deleted inode statistics from etcd automatically
- Implement OSD address selection from a subnet, thus removing the need to specify
OSD addresses in startup scripts explicitly
Bug fixes:
- Fix client failover in case of etcd shutdown or crash (make client survive etcd failures)
- Stick to the last live etcd in OSD and mon to prevent random failures when one of etcds is down
- Fix incorrect copying of data from journal to the data device which could lead to data corruption
- Prefer local etcd IPs in OSD
- Remove the total PG count restriction in optimize_change which was sometimes leading
to inability to redistribute PGs over OSDs
- Fix error response parsing on a failed pg state report
- Fix slow linear writes with RDMA by changing default buffer settings
- Fix possible 'TypeError' in openstack nova when using Vitastor cinder driver
- Fix bugs in vitastor-cli create, ls, rm, modify commands
Patch changes:
- Add a patch for libvirt 7.6
- Add patches for QEMU 6.0 and 6.1
- Fix config file path XML location parsing in libvirt patches
- Replace _ with - in QEMU options
- Fix possible 'TypeError' in openstack nova when using Vitastor cinder driver
- Fix possible crashes of QEMU block driver in case of incorrect options
