Storage system running areca raid with DRBD replication between two servers. Scst provides FC and iscsi targets. I have a number of these systems in use however one in particular is giving me grief. From time to time a kernel panic is issued and DRBD gets into a very odd state. 6 DRBD devices replicated. On the node with the kernel panic it continues to stay Primary/Secondary with no OOS numbers increasing. On secondary any number of devices will go WFConn while others stay up and continue to stay in sync. Spinlock with IRQsave appears. I've found some stability from sendpage disabled however that seems out of place since this is a baremetal device. Any insight would be appreciated. kernel 3.14.51 Gcc 4.8.5 drbd 8.4.6 git pull http://pastebin.com/DSxj4WMi Ross
