Hi, DRBD 9.0.10 and DRBD Utils 9.2.0 are out. There have not been any changes to the kernel part since rc2. Utils got increased VCS support and a minor bugfix in drbdmon. Let me quote Phil's announcement for rc1 as a recap what changed: On Tue, Dec 05, 2017 at 02:29:26PM +0100, Philipp Reisner wrote: > Hi, > > In this development cycle we could look at a bug that was known > for some time but needed a few calm weeks to be understood and > fixed.

That is cured with drbd-9.0.10. drbd 9.0.10-1 (api:genl2/proto:86-112/transport:14) -------- * Fix resync of two secondary nodes in the presence of a 3rd node that is primary (maybe with disk or diskless); Fixed the race condition that caused the resync to sometimes not terminate * Improve connection behavior with autopromote enable one node Primary and udev present. The problem was that if udev opens the device on the Secondary side "in the right moment" the connection attempt was aborted. Fixed that by waiting until udev closes the device again. Improves connect speed! * Fix in memory alignment of DRBD's struct bio. Got offseted by one due to a buggy compat code. Only affects architectures that choke on unaligned word accesses. I.e. Power and ARM not x86_64. * Improve the quorum implementation, so that is works nicely with for the purpose of replacing fencing with quorum in a Pacemaker setup. Quorum lost affects the completion status of writes in flight; Quorum state is visible to user-space; a new meta-data flags quorum-lost to handle a corner case * Ensure compatibility with upstream Linux kernel 4.14 http://www.linbit.com/downloads/drbd/9.0/drbd-9.0.10-1.tar.gz https://github.com/LINBIT/drbd-9.0/tree/drbd-9.0.10 drbd-utils 9.2.0 -------- * Japanese man pages * initial vertias cluster agent support * quorum integration (including agents) * improve drbd9 (mesh)/drbd-proxy integration * pull fixups from 9.1.1 branch * switch to github * drbdmon: page naviagation/quorum * debian: add mount as dependency http://www.linbit.com/downloads/drbd/utils/drbd-utils-9.2.0.tar.gz https://github.com/LINBIT/drbd-utils/tree/v9.2.0 Best regards, rck -------------- next part -------------- A non-text attachment was scrubbed...
