Debian bullseyes (Debian 11.0) entered 'hard freeze' two weeks ago and we
have customers that want to use DRBD and LINSTOR on that
platform. Unfortunately, I made a stupid mistake a few weeks back and that
broke the kernel compat for kernel 5.10 (which comes with bullseye). So, here
is a release of the drbd-9.1 branch that works on bullseye and also releases
a few fixes we have in the tree.
Well, did you ever try to build a LINSTOR cluster containing mips64 and
We did, and we found out that it breaks in a small detail in DRBD's size
negotiation code if the node's architecture has different page
sizes. Mips64 has a default page size of 16k.
And some other esoteric things...
Expect the 9.0.29, and another 9.1.x release in about one month from now.
* fix a temporal deadlock you could trigger when you exercise promotion races
and mix some read-only openers into the test case
* fix for bitmap-copy operation in a very specific and unlikely case where
two nodes do a bitmap-based resync due to disk-states
* fix size negotiation when combining nodes of different CPU architectures
that have different page sizes
* fix a very rare race where DRBD reported wrong magic in a header
packet right after reconnecting
* fix a case where DRBD ends up reporting unrelated data; it affected
thinly allocated resources with a diskless node in a recreate from day0
* changes to socket buffer sizes get applied to established
before it was applied after a re-connect
* add exists events for path objects
* fix a merge-mistake that broke compatibility with 5.10 kernels
