Vitastor 2.4.4 released

2025-12-01

  • Implement vitastor-kv rescue command which dumps all readable blocks from the database regardless of the tree structure and allows to recover a corrupted database.
  • Simplify primary OSD selection - use just PG number instead of the hash. This allows to distribute primary OSDs more evenly and reach better read speeds.
  • Fix vitastor-kv-stress hang on parallel list & reopen.
  • Fix CAS writes without immediate_commit. Fix is sufficient for vitastor-kv to operate correctly in non-immediate_commit pools.
  • Fix NFS ACCESS calls for broken inodes (allow root access to them).
  • Fix broken vitastor-kv-stress --runtime parameter.
  • Fix bad vitastor-kv dump output buffering leading to incorrect JSON in dumps.
  • Fix writing garbage from uninitialized memory to the empty space in VitastorKV DB.
  • Refactor some code in preparation to the release of the new log-structured metadata store.
  • Replace assert(done != expected) error message, probably caused by kernel issues with zero-copy TCP send, with a more concise error description.
