drbd-utils v9.28.0-rc.1
Dear DRBD users,

this is the first RC of the upcoming drbd-utils version 9.28.0. In
contrast to the recent releases this one contains a bit more exciting
news:

- 8.3 code is gone

- events2: netlink messages (used between utils in user space and the
kernel module) can be sent out of order. So far this was more
theoretical, but more modern kernels actually seem to actually make
use of it. We put code in place that reorders such messages if sent
out of order. This is particularly important for software that depends
on events2 processing. The actual impact might vary, but just to name
a few that make use of events2 processing: drbd-reactor, drbdmon,
LINSTOR.

- udev: drbdsetup got a new "udev" subcommand that replaces drbdadm's
"sh-udev" command. This allows to have the actual (in kernel) state
reflect the udev state more closely compared to drbdadm which used res
file information. It avoids problems if the res file can not be parsed
or problems if the hostname is not set yet (e.g., systemd-udev starts
before the hostname is set). All in all we hope this solves udev
related issues we saw previously.

there are all kinds of fixes and improvements all over the place like
improved Pacemaker support for 2.1.7, or tweaks for the promotion score
if force-io-error is true, which will help drbd-reactor. More details
can be found in the changelog or the git history.

Please test, if we don't find any bugs the final version will get
released in about a week from now.

Regards, rck
