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 [DRBDmon: O(log(n)) lookup of unicode code point display lengths · LINBIT/drbd-utils@e06af0e · GitHub](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.
