Hi, We have 2 servers wich have 8 drbd device, each device is mounted and exported with nfs-kernel-server. the first step was just one server up with all devices set as primary and mounted. the first time I've started drbd service on the second servers, we got a big nfs dead lock, due to a misconfiguration in the drbd.conf file, they wasn't exactly identical. I have added the parameter 'after "logs"' on the second node but not on the first. So, the drbd synchronisation was lock as expected, but the nfs server too. Even if we was able to access localy on drbd mounted partition, all nfs exports were completely down until we stoped drbd on the second node. I would like to know if it's a behaviour expected or, there are a lock in the kernel that can be fixed to avoid this case ?
