Hi, during the last week before the release, we let another few fixes in, which again, are really hard to trigger.
Two minor features are coming with this release: 1 Resource renaming 2 ability to disable the upper bandwidth boundary for the resync controller 9.0.28-1 (api:genl2/proto:86-119/transport:14) -------- * fix a regression introduces with 9.0.25; it failed to determine the right device size and the connection hangs in WFBitmapS/WFBitmapT repl state; to trigger this you need to do a partial resync to a new node with different backing device size * fix an issue with netlink packets processed in parallel on multiple CPUs; the bug caused drbdadm adjust failing in very rare cases * fix a very rare occurrence of a reconciliation resync getting stuck * fix a race condition that causes a detach operation to hang; it is very hard to trigger * fix a kernel OOPS (via a BUG()) upon adding a timer twice under very rare timing * fix a counter imbalance that could lead to assertion messages when a protocol A peer disconnects with a certain timing * fix a rare race with receiving bitmap and a state change while establishing a connection * fix UUID handling to avoid false split-brain detections; this bug got triggered an isolated primary that gets demoted, and temporal network interruptions among the remaining nodes * fix resync decision to obey disk states when the generation UUIDs are equal; the effect of this bug was that you could end up with two Outdated nodes after resync * fix concurrent disk-attach operations * Fix possible kernel warning regarding an inbalance of backing device link/unlink * move some amount of kernel backward compatibility code moved from the old method (drbd_wrappers.h) to new cocci semantic patches * add support renaming resources while its devices might be in use and process IO requests * Allow setting c_max_rate to 0 with the meaning that the resync controller has no upper limit for the resync speed https://www.linbit.com/downloads/drbd/9.0/drbd-9.0.28-1.tar.gz https://github.com/LINBIT/drbd/commit/8db03a6344e74e5c160294d80188dc31b785db61 _______________________________________________ Star us on GITHUB: https://github.com/LINBIT drbd-user mailing list [email protected] https://lists.linbit.com/mailman/listinfo/drbd-user
