Don't know.... Found this link http://elrepo.org/bugs/view.php?id=583 where it reports: "A quick google search seems to suggest this related to the expanded kernel stack size (to 16k) in kernel-3.16. So I guess we can assume RedHat have backported that to their 6.7 kernel. Doesn't seem to cause any issues AFAICS, but it's probably not a bad idea to rebuild modules against the 6.7 kernel. We currently build nvidia packages against the RHEL-6.5 kernel for increased backward compatibility." > > Oct 17 11:36:28 s2 kernel: drbd infiniband: conn( StandAlone -> > > Unconnected ) Oct 17 11:36:28 s2 kernel: drbd infiniband: Starting > > receiver thread (from drbd_w_infiniba ) Oct 17 11:36:28 s2 kernel: > > drbd infiniband: receiver (re)started > > Oct 17 11:36:28 s2 kernel: drbd infiniband: conn( Unconnected -> > > WFConnection ) Oct 17 11:36:39 s2 kernel: drbd infiniband: sock_recvmsg > > returned -11 Oct 17 11:36:39 s2 kernel: drbd infiniband: conn( > > WFConnection -> BrokenPipe ) Oct 17 11:36:39 s2 kernel: drbd infiniband: > > short read (expected size 8) Oct 17 11:36:39 s2 kernel: drbd infiniband: > > Connection closed > > Oct 17 11:36:39 s2 kernel: drbd infiniband: conn( BrokenPipe -> > > Unconnected ) Oct 17 11:36:40 s2 kernel: drbd infiniband: conn( > > Unconnected -> WFConnection ) > > > > I'm using latest centos 6 with 2.6.32-573.7.1.el6.x86_64 kernel and drbd84 > > from elrepo. > Last time I checked, it "worked for me". It works with drbd 8.3. How can i continue in the debug process? Is there any loglevel i can increase in drbd kernel module? > > Oct 17 11:36:54 s2 multipathd: drbd0: remove path (uevent) > > Multipath on top of DRBD? really? I'm not using multipath on top of drbd. Will exclude it from /etc/multipath.conf so that this log doesn't appear. Thanks Nuno Fernandes
