Hi, I have a major issue. I was running fine with a 4 node cluster for a few days and then I copied some data to the GFS share and within a few hours the gfs share went down. I restarted the cluster and now I am getting this error from dmesg and it also says removing device node /dev/diaperedmd0: GFS: Trying to join cluster "fsck_dlm", "SAN1:VserversFS" lock_harness: can't find protocol fsck_dlm GFS: can't mount proto = fsck_dlm, table = SAN1:VserversFS, hostdata = I have removed the storage server from the cluster and shutdown gnbd and I have been running gfs_fsck for about 24 hours and it still hasn't completed. I have a 750GB raid 5 setup and I can't remount or anything. What do I need to do to fix this? Here is what gfs_fsck reports: Initializing fsck Initializing lists... Initializing special inodes...
