Vitaliy Filippov	7972502eaf	Release 1.3.0 ... New features: - RDMA without ODP - much faster and all cards are now supported, not just Mellanox - VDUSE in CSI - faster, more stable and can even recover after CSI pod restart! - Reserve journal space for stabilize requests dynamically to prevent stalls under load with EC - Raise default NBD timeout from 30 to 300 seconds and allow to take it from /etc/vitastor/vitastor.conf - Remove explicit etcdUrl/etcdPrefix K8S storage class parameter support to prevent etcd migration issues for volumes created with these parameters - Support QEMU 8.1 and pve-qemu 8.1 Bug fixes: - Fix RDMA connection (and thus memory) leak - Fix rare crashes under load due to incorrect io_uring queue size tracking - Fix monitor statistics aggregation in case of empty /osd/stats keys - Fix crash on unknown long argument to vitastor-disk - Allow trailing comma in JSONs again - Fix crash on attempts to dump a long listing of objects "to stabilize" or "to rollback" in a slow op	2023-12-04 02:36:43 +03:00
Vitaliy Filippov	5524dbdab7	Release 1.2.0 ... New features: - Implement CSI volume expansion - Implement CSI volume snapshots - CSI driver now requires Kubernetes >= 1.20 Bug fixes: - Important bug fix for EC: fix EC n+k, k>=2 read recovery in ISA-L version returning incorrect data when reading at least the second chunk out of multiple missing chunks without reading the first one. All users of EC n+k, k>=2 should upgrade as soon as possible, and upgrade should be conducted with downtime: first stop all clients (VMs/containers), then all OSDs, then upgrade and restart everything. - Fix unstable statistics aggregation in monitor (affecting vitastor-cli status and df) - Make udev not wait for OSDs to start during boot - Do not report negative numbers of offline PGs in vitastor-cli status when changing PG count - Report both old and new PG counts in vitastor-cli df when changing it - Fix OSDs sometimes not starting with "The code only supports journal versions 1 and 2, but it is 2 on disk" error after upgrading from pre-1.0 versions and letting OSDs run for some time - Fix monitors sometimes returning old PG count back after OSD configuration changes - Make monitor PG changes more stable and timeout errors less probable	2023-11-05 01:48:57 +03:00
Vitaliy Filippov	8222e3c77d	Release 1.1.0 ... New features: - Implement [client writeback cache](docs/config/client.en.md#client_enable_writeback) - Add the third I/O mode: [O_DIRECT|O_SYNC](docs/config/osd.en.md#data_io) (good for Optane) - Reduce load on etcd by splitting OSD lease and statistics reporting intervals: [etcd_stats_interval](docs/config/osd.en.md#etcd_stats_interval) (default 30 sec) - Make MON automatically filter OSDs by layout (block_size/immediate_commit/bitmap_granularity) to prevent "refusing to start PGs of this pool" errors on misconfiguration - Support running fio benchmarks on systems without io_uring - Make QEMU driver compatible with QEMU 8.1 - Document usage of [vhost-user-blk](docs/usage/qemu.en.md#vhost-user-blk) Bug fixes: - Fix resizing disks in QEMU driver (for example, in Proxmox) - Fix "unexpected result" in Proxmox driver by making CLI flush output on exit - Remove unneeded block_size mismatch warnings on pools without matching PGs - Fix possible segfault in vitastor-cli ls -l (usually with deleted pools) - Fix QEMU driver compatibility with systems without io_uring - Fix monitor eating 100% CPU when etcd is down (caused by infinite retries) - Fix potential incorrect write processing with snapshots (not caught in tests but could probably lead to client hangs) - Fix buffer insertion in cluster_client (not caught in tests but could probably lead to incorrect writes in rare cases) - Fix rare OSD crash during sync operation processing - Fix a reenterability issue in cluster_client not reproducible in QEMU/fio, but reproducible with the currently developed K/V database implementation - Fix deletion of the first modified object - OSDs could crash if you modified the same object a lot of times, then deleted it, and then modified it again - Fix the fio_sec_osd test tool	2023-10-28 00:33:06 +03:00
