Hi all, I installed from source DRBD 8.3.11 on RHEL 5.7's Xen kernel (2.6.18-274.el5xen). I've got RHCS setup using rgmanager, but this issue arose without rgmanager running, so I doubt it relates. When I have the interfaces' MTU set to 9000, the DRBD resource will hang when bringing the second node up to Primary (dual primary config). The attach and connect steps worked fine and the first node goes to Primary fine. Interestingly enough, while debugging it, I 'ifconfig eth1 mtu 1500' one node, and before I could do it to the second (hung) node, it was fenced (using the obliterate-peer.sh script to tie it into the cluster). So *some* level of communication was working. I'm guessing though that the messages between DRBD are well below 1500 bytes though, so that might have been the problem. Any way to debug this? If it looks like a DRBD bug, I'd be happy to file a bug report, I just need to know where. :) -- Digimer E-Mail: digimer at alteeve.com Freenode handle: digimer Papers and Projects: http://alteeve.com Node Assassin: http://nodeassassin.org "At what point did we forget that the Space Shuttle was, essentially, a program that strapped human beings to an explosion and tried to stab through the sky with fire and math?"
