I just had my second DRBD cluster fail after updating kmod-drbd90-9.1.8-1 and then upgrading the kernel. I'm not sure if the kernel update broke things or if it was because it caused after the reboot. About 2 weeks ago there was an update (kmod-drbd90-9.1.8-1) from elrepo, which got applied. Bu

Dear DRBD-users, this is version 9.21.4 of drbd-utils. It is a bugfix release, but if things worked for you so far there is no too urgent need to update. The fixes were triggered by customers in rare edge cases like an uncommon drbd-proxy setup. The second fix is for the sh-ip subcommand that segf
