The bugs fixed in this release are mostly exotic corner cases. One fix is that a fatal user error causes the machine to enter an annoying out-of-memory condition in previous DRBD releases. The developers have switched their interest to the 9.3 branch. I want to roll it out internally, following the so-called 'eat your own dog food' strategy, before I declare it a final release. I plan to release 9.3.0 early next week. 9.2.16 (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 two 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 and 6.18-rc6 https://github.com/LINBIT/drbd/commit/3a0f974085c481737e13fb39f03ccd85b63eb7df https://pkg.linbit.com//downloads/drbd/9/drbd-9.2.16.tar.gz 9.3.0-rc.6 (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 * Give filesystems mounted on DRBD a chance to bring their on-disk representations into a consistent state before suspending I/O. * Fixes for resync without replication * All fixes from 9.2.14, 9.2.15 and 9.2.16 * Compatibility with Linux-6.17 https://github.com/LINBIT/drbd/commit/673d0dba8c25319ea84c2ebc71a094b1678906b5 https://pkg.linbit.com//downloads/drbd/9/drbd-9.3.0-rc.6.tar.gz
