Very nice, thank you for your work!!
Waiting for proxmox package to try it, hope to see it soon so I have
something interesting to do for my holidays :-)

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:

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. So, no more resyncs that stuck near the end (~95%)
On the side of new features: The quorum feature got advanced a
lot and is now usable with pacemaker. It is very nice way how
data-divergence (aka split-brain) can be completely avoided without
building proper fencing infrastructure!!
It is only applicable if you have the DRBD resource on at least 3 nodes.
Last not least, with Linux-4.11 upstream introduced a bio operation
that escaped our attention. The result is drbd-9.0.x (x <= 9) OOPSes
on kernel 4.x (x >= 11). 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
