This release includes a bunch of important bugfixes for erasure-coded setups with disabled immediate_commit. After these fixes, "test_heal" OSD killing test now passes fine with EC: - Fix cluster write stalls with "Error while doing flush on OSD xx: -16 (Device or resource busy)" in OSD logs possible in EC setups with disabled immediate_commit by selectively syncing nonsynced objects on STABILIZE/ROLLBACK (https://github.com/vitalif/vitastor/issues/51) - Fix other EC + disabled immediate_commit problems: - Fix "opcode=5 retval=-2" errors happening on SYNC retries - Fix non-working "pagination" during PG dirty object flushing - Fix write operations not continued correctly after dirty object flushing - Fix incorrect parity read-modify-write calculation when writing into a lost chunk - Fix OSDs losing left_on_dead PG state of non-clean PGs and thus not removing junk data in the cluster - Fix a small memory leak caused by bad indexing of EC recovery matrices - Fix a rare use-after-free in cluster_client caused by a reenterability issue - Fix vitastor-cli create command syntax in the CSI driver - Allow to start OSDs without local store for tests - Fix memory allocation error in disk_tool_meta for non-standard metadata block sizes - Fix delete operations received before loading pool metadata crashing OSDs with "null pointer exception" - Improve "theoretical performance" Russian documentation New features: - Implement online configuration update for some parameters. Documentation is coming soon :) |
