Hello drbd users,
The next releases are coming soon. Today I have the honour to announce
the availability of release candidate 1 for drbd-9.2.16 and
drbd-9.3.0-rc.5. The latter is already at 5, since we did some internal
release candidates. This time it looks good.
Regarding the fixes, everything is minor and boring.
drbd-9.3 is where the exciting new features are. This time, it got
support for tunable bitmap granularity and for disabling the
change-tracking bitmap entirely.
Please help test the release candidates. I plan to do the final releases
in one week if nobody finds a showstopper.
9.2.16-rc.1 (api:genl2/proto:86-101,118-122/transport:19)
--------
* Do not trigger the OOM-killer when allocating a too-big dirty
bitmap during attach; instead, fail the attach operation.
* Do not flush half-created packets out while closing a connection
* Fixed a bug that, in rare circumstances, when flapping between
Ahead and resync, can lead to a divide by zero error.
* Fixed a bug that caused DRBD to send too many P_PEERS_IN_SYNC
packets when finishing a resync; on huge devices ( >10TB), that led
to temporarily higher I/O latencies.
* Fixed an unhandled corner case to automatically reintegrate an I/O
frozen primary into a larger partition that created a newer data
generation
* Compatibility with Linux-6.17

9.3.0-rc.5 (api:genl2/proto:86-101,118-123/transport:19)
--------
* Implemented support for bitmap granularity between 4k and 1M,
including exchanging bitmaps with peers with a different bitmap
block size
* Add support for omitting bitmap allocation for standalone devices
* Explicit config option for drbd8-api-compatibility mode
* Fixes for resync without replication
* All fixes from 9.2.14, 9.2.15 and 9.2.16
* Compatibility with Linux-6.17
