- Fix one more bug in old store checksums O_o - checksum verification wasn't
working correctly on reads quickly after small initial offsetted writes
(when a BIG_WRITE was read from the journal).
- Fix clients possibly not destroyed after being switched to RDMA. Not 100%
verified, but in theory it could rarely lead to PGs hanging in peering/stopping
states with RDMA enabled.
- Use vitastor-cli in the Cinder driver for modifications instead of direct etcd
interaction.
- Fix mon_https_ca parsing.
- Fix Docker install.sh, add instructions for Podman.
A single urgent fix for the new store: metadata was written incorrectly when
filled metadata area exceeded 4 GB due to a simple & stupid 32-bit integer overflow.
This was leading to OSDs corrupting metadata and being unable to start on the next
run.
The bug affected only the new store (meta_format=3) and OSDs with metadata area size
larger than 4 GB. You can check your OSD metadata area size by checking `data_offset`
in `vitastor-disk read-sb /dev/vitastor/osdXX-data` for single-disk OSDs or
`blockdev --getsize64 /dev/vitastor/osdXX-meta` for hybrid OSDs.
If you're affected, it's highly recommended to:
- Install updated packages without restarting OSDs
- Restart OSDs **one by one**
- If a restart of an OSD triggers "has_degraded" rebalance - wait for it to finish
before restarting another OSD
- If an OSD fails to start with "double-claimed" errors in the log - purge and recreate it,
and again wait for "has_degraded" rebalance to finish before proceeding to the next OSD
New store bug fixes:
- Fix very slow OSD startup (hours) possible in unlucky cases
- Fix incorrect garbage entry validation on start in some cases, preventing OSD startup
- Fix small_write_throttling not functioning and either hanging or crashing OSDs
- Fix "different fact_versions returned from subops" error possible with EC in some cases
- Add a recovery option for the new store: skip_corrupted_meta_entries
- Disable intent writes (even 4k) for hybrid OSDs by default for better write buffering
Other changes:
- Fix chmod/chown of a new empty VitastorFS root directory not working
- Fix vitastor-dd treating all < 32k reads as always empty
- Fix vitastor-disk always setting 32k csum_block_size for HDDs when checksums are enabled
- Fix OSD missing PG state updates and PGs hanging in "starting" in rare cases
- Fix a possible OSD crash with "map::at" message in rare cases when stopping a client
- Fix a possible OSD crash on start when RDMA is available but fails to initialize
- Fix removal and overwriting of totaled objects (objects with all corrupted copies)
- Do not allow data_block_size < 8*bitmap_granularity
- Remove RDMA ODP (On-Demand Paging) support
- Update antietcd to 1.2.4
- Update Docker build to Debian Trixie
- Add packages for AlmaLinux 10
