Dear DRBD users,

this is the first RC of the upcoming version 9.35.0. It contains
improvements and fixes all over the place. Highlights include a major
DRBDmon update, various drbdmeta metadata conversion improvements, and
SELinux improvements. This release contains a lot more code than any of the
previous I remember the last ~10 years, so please test.

I had to force push github master today, sorry for the inconvenience. master
points at https://github.com/LINBIT/drbd-utils/commit/e06af0ef747cf8e1745c27c1ef29bdcf3b9debef
This mail including the hashes (as well as the release commit and tags are
gpg signed, so nothing to be too worried about).

IMPORTANT - read before upgrading on Debian-based systems:
==========================================================
This release splits drbd-graceful-shutdown.service into separate
disconnect and down services. Unfortunately, when upgrading from any
previous version that ships drbd-graceful-shutdown.service (9.26.0 up
to and including 9.34.0), the *old* package's prerm stops that service
during the upgrade. Its ExecStop runs "drbdsetup down all", which takes
down all DRBD resources on the live system in the middle of the package
upgrade. RPM-based systems are not affected.

Before upgrading drbd-utils on a Debian-based system, neutralize the
ExecStop with a runtime drop-in:

  mkdir -p /run/systemd/system/drbd-graceful-shutdown.service.d
  printf '[Service]\nExecStop=\n' >/run/systemd/system/drbd-graceful-shutdown.service.d/50-upgrade.conf
  systemctl daemon-reload
  # then upgrade drbd-utils

The drop-in lives in /run and is self-cleaning; it is gone after the
next reboot. The service got split into 2 separate services
(drbd-graceful-{down,disconnect}.service), so you can keep the override for
the old one till you reboot, you don't need to remove the file or reboot
immediately.

If you upgraded without this step and your resources went down,
"drbdadm up all" (or restarting linstor-satellite) brings them back up.

Please test, if we don't find any issues the final release will be about
a week from now.

Regards, rck
