Hi all, I've got very similar problem to
http://lists.linbit.com/pipermail/drbd-user/2015-July/022243.html that. OS: Red Hat Enterprise Linux Server release 6.7 (Santiago) kernel: kernel-2.6.32-573.1.1.el6.x86_64 DRBD: kmod-drbd84-8.4.6-1.el6.elrepo.x86_64 Two node cluster where after upgrade to the lastest kernel + Corosync Pacemaker DRBD I've encoutered problems. Secondary does a full resync, seems to successfully finish it but then 'PingAck did not arrive in time' happens and the resync repeats. This keeps happening in a loop thereafter. Please note that I could not observe any network problems, no problems with the resync or any other services, except the very end of the resync. I've tried reboot the secondary (target) node, invalidating the data and forcing full resync by hand, wating about 4 rounds of the loop :) But to no avail. Currently I'm in process of downgrading the kernel to see what happens but as it's a production server this will take little time (outage) :/ I'm also fairly new to DRBD so please point out anything obvious I may be missing. thanks v Logs: primary node (SyncSource) Aug 12 15:22:45 dbpg02 kernel: drbd drbd0: PingAck did not arrive in time.
