Vitastor 3.2.2 released

Small bugfix release.

• New store (thanks Changwei Ye)
  • Fix rejected compaction when an object is already overwritten again
  • Reduce superblock I/O amplification introduced after previous correctness fixes
• Fix possible vitastor-cli rm crash with assert(rwo->todo == 1) introduced in 3.2.1
• Fix replicated objects possibly incorrectly transitioning to the INCOMPLETE state after multiple failed partial writes
• Fix possible “operation sequencing broken … expected num 2, got 3, stopping client” possible when a cluster is overloaded by peering/OSD flaps

Vitastor 3.2.1 released

• Blockstores
  • Add more asynchrony to the chaos test to uncover more issues…
  • …and fix them (~6 in the old store, ~9 in the new store)
  • Fix size check for journal_offset when sharing meta device (thanks Changwei Ye)
• Network layer
  • Correctly handle out-of-order zero-copy notifications (rare but possible in theory)
  • Fix double checksumming of header in proto_checksums=full mode
  • Add rxbounce option for Windows guests with TCP and enabled checksums
  • Close stopped peer sockets early to prevent hung zerocopy notifications and slow failover (~15 min instead of ~10 sec)
• OSD
  • Do not die on local blockstore modification errors (irrelevant since added write error handling)
• CSI
  • Fix VitastorFS NFS daemon lifecycle (thanks Dmitry Naumov)
  • Use a newer qemu-storage-daemon in CSI
• vitastor-cli
  • Add dd opool option
  • Fix rm with “inverse” optimisation incorrectly removing layer data before rename possibly leading to incorrect reads from child images during removal of an older-than-latest snapshot
  • Fix a possible hang in merge and derived commands (rm, flatten)
  • Fix mistakes in the serve OpenAPI spec (thanks Stepan Rabotkin)
  • Fix possible segfaults in serve due to invalid request parsing (thanks Vincent Schweiger)
  • Fix serve no-HTTPS mode (thanks both :))
• Build
  • Fix non-x86 builds failing due to unsupported xxhash x86dispatch
  • Forcibly enable assertions in all builds to remove build profile dependency
  • Fix QEMU driver build with QEMU < 10.2

Vitastor 3.2.0 released

This is a bugfix release, and most of the fixes came from a new approach to testing: a chaos test for the block store, which now runs in CI on every change.

Also thanks to Yury Luneff from MIND Software for another part of the fixes.

Vitastor 3.1.0 released

Finally, the security release!

New features:

• Fully secure cluster setup support:
  • etcd transport encryption (TLS/mTLS)
  • OSD transport encryption (AES-GCM), header-only by default, thus very fast
  • End-to-end image data encryption (AES-XTS)
  • Optional external Vault AES-XTS key storage
  • Certificate-based authentication
  • Optional user privilege support with etcd- and OSD-based access control
  • xxhash3 transport checksums (data-only by default)
• New on-disk checksum algorithm option: xxh3_32 - xxhash3 truncated to 32 bits
• DNS name support for etcd and Vault URLs
• HTTP API server mode: vitastor-cli serve
• Mixing CAS and non-CAS writes within a single client instance is now allowed and works correctly
• make-etcd can now initialize the whole cluster by copying configs and starting other nodes through ssh
• Debian 10 (Buster) and CentOS 7 support is completed, packages won’t be updated anymore

Vitastor 3.0.16 released

Quite a bit of fixes, but mostly small. :-)

Most interesting fix affect pools without immediate_commit (for desktop SSDs): fixed corner cases in the commit (sync) operation and CAS write operation (used, for example, in VitastorFS).

Other notable changes: “double-claim” bug is fixed in the new store, and changes are made to reduce etcd load during active PG state switching.

You can read the details below.
