Vitaliy Filippov	5280d1d561	Release 1.4.0 ... New features: - Intelligent recovery/rebalance speed auto-tuning to reduce its impact on clients (see README -> Features) - Auto-restoration of dead VDUSE daemons in CSI plugin - Add vitastor-disk update-sb command - Update QEMU for Debian Bookworm to 8.1 and use it for CSI plugin Bug fixes: - Fix pools SOMETIMES staying inactive after stopping a node due to OSDs not reacting to PG state changes caused by incorrect full reload of state from etcd on reconnection - Make monitors retry pool configuration changes quickier which fixes them being unable to apply changes when an ongoing rebalance is quickly making a lot of PGs clean - Fix CSI plugin not accepting array of strings as etcd address in /etc/vitastor/vitastor.conf - Allow multiple interfaces with the same IP address, for "simple routed" full mesh network - Do not ignore loopback addresses for OSD network (to make ECMP setups with frr possible) - Fix a rare client crash during OSD reconnections - Only treat data partitions as existing OSDs in vitastor-disk prepare - Remove etcd parameter from default command examples - Fix reported free space sometimes changing non-immediately after deletion of data from OSDs - Fix a possible OSD crash on print_slow when bs_op is NULL - Use the same etcd_ws_keepalive_interval in mon as in OSD - Fix mon not using values from config when /config/global is not present - Remove pve-storage-portal-dns-list format for vitastor_etcd_address - Parse log_level in cluster_client - Fix vitastor-nbd image existence check not working because of non-zeroed inode_watch fields - Do not warn on EPIPE in client unless log_level is raised explicitly - Fix incorrect error in CSI when searching for the device in /sys - Remove 2 last prints to stdout in etcd_state_client - Fix a possible OSD crash when checking corrupted journal entries	2024-01-12 01:28:33 +03:00
Vitaliy Filippov	a1c7cc3d8d	Release 1.3.1 ... Hotfix to 1.3.0 - new "journal space reservation" had a bug which caused OSDs to crash with EC and without immediate_commit.	2023-12-04 18:35:09 +03:00
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
