Hello, I'm attempting to run drbd 8.3.4 against Linux 2.31.4. I'm making the (possibly incorrect) assumption that from the Changelog,
8.3.3 * Following Linux upstream changes 2.6.31 that I'm ok on the 2.6.31 kernel series. I've patched the kernel directly and can see from root [ /sources/drbd-8.3.4 ]# cat /proc/drbd version: 8.3.4 (api:88/proto:86-91) GIT-hash: 70a645ae080411c87b4482a135847d69dc90a6a2 build by r...@atuin-1, 2009-10-15 11:36:31 that the patch has been applied correctly. My problem is that when I attempt to create the metadata I get a kernel Oops, output of which is attached. I've also included my drbd.conf, very basic, but there you have it. Problem is 100% reproduceable both on this machine and it's (identical) counterpart which will (eventually) form the second node in the cluster. I've wondered if it is a kernel compatibility problem, I've also wonder if drbd doesn't like to run on a software mirror (md device), though am guided by "You can stack DRBD on top of md, md on top of DRBD is nonsense, however." from http://www.linux-ha.org/DataRedundancyByDrbd. Further discussion on this list from a couple of years ago is quite confusing! I wonder if anyone can provide some advice?
