Is lock_gulmd running? Did you name the >filesystem with the correct -t option? Oh, yes. The module "lock_gulm" and the daemon "lock_gulmd" are both absent,I get the reason. So which lock module does work better on GFS 6.1+kernel 2.6? Such as performance and stability? lock_dlm or lock_gulm? > >When you are using lock_nolock to mount the filesystem, are you doing it >from more than one node? lock_nolock is ok for a single node, but it >doesn't do any locking, so if you mount it from a second node you will >corrupt your filesystem and see kernel panics.
