I also had a problem starting DRBD with my Corosync/Pacemaker cluster after upgrading drbd8-utils to 8.4.3.
This is a line from the log file where it is failing: Apr 24 08:21:02 www6a lrmd: [1183]: info: RA output: (p_drbd_r0:0:start:stderr) Could not connect to 'drbd' generic netlink family Command 'drbdsetup new-resource r0' terminated with exit code 20 I am running Linux kernel 3.5.0-48 on Ubuntu 12.04.4 LTS # uname -a Linux www6a 3.5.0-48-generic #72~precise1-Ubuntu SMP Tue Mar 11 20:09:08 UTC 2014 x86_64 x86_64 x86_64 GNU/Linux DRBD module was always at version 8.3.13 # cat /proc/drbd version: 8.3.13 (api:88/proto:86-96) srcversion: C0F510A918B92928FB51EE3 I was able to fix it by downgrading drbd8-utils again: # apt-get install drbd8-utils=2:8.3.11-0ubuntu1 Also removing startup scripts: # update-rc.d -f drbd remove -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1185756 Title: drbd8-utils not compatible with linux-lts-raring kernel in 12.04 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/drbd8/+bug/1185756/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
