Hello,all. How can I use the LockProtoName: lock_gulm,lock_nolock? When I use lock_gulm to make gfs filesystem,I can not mount the filesystem. When lock_nolock, the gfs can be mounted,but when writed, the kernel paniced. Is that true that I can only use lock_dlm in GFS 6.1pre2 + kernel 2.6.8.1 ? Thanks for any reply! Best regards! Luckey Sun
