Hello DRBD-users,
This DRBD release is about four weeks late compared to the usual release pace. The reasons for this are that the discovery of fresh bugs was a bit slow in this cycle, and those bugs were hard to crack. It took some time to understand both bugs to the extent that it allowed us to write reproducers for our test suite. By the way, the customer affected by one of these issues run more than 22,000 drbd resources in a linstor cluster stretching over more than 350 nodes, with about 7.9 PB under LINSTOR management. The DRBD RDMA transport depended on the behavior of the Melanox cards. We fixed that and verified the improvements by running it on intel RDMA cards. Last but not least, we invested quite some time in tracking all Linux upstream developments and have DRBD compatible with 6.11 and the not-yet-released 6.12 kernels. I intend to branch off a new series (e.g., 9.4.x) soon, and I will no longer do releases in the 9.1.x branch. We will discontinue support for RHEL7 kernels (and distros equally old) with the new branch. We will add performance improvements for the data path, features for multi-site deployments, and an optionally new way of doing resyncs. Please help test the release candidates. https://pkg.linbit.com//downloads/drbd/9/drbd-9.2.12-rc.1.tar.gz https://github.com/LINBIT/drbd/commit/1eeb1fcfccbabfaf2d22a376c1f1a2a90eda3b2b https://pkg.linbit.com//downloads/drbd/9/drbd-9.1.23-rc.1.tar.gz https://github.com/LINBIT/drbd/commit/19a7625af848b7c310b1707060b00ca0773db109
