[Linux-cluster] error 94?

[Spencer Marshall]

I have created the logical volume on an already created volume group, 
mkfs using

mkfs.gfs2 -j 8 -t vmware_cluster:lv_sharedroot -p  lock_dlm 
/dev/vg/lv_sharedroot

I am trying to mount a gfs2 partition, and get
/sbin/mount.gfs2: error 94 mounting /dev/vg/lv_sharedroot on /mnt/cluster

What have I done wrong please?

installed:
kernel: 2.6.19.1-5
CONFIG_GFS2_FS_LOCKING_DLM=y
CONFIG_DLM=y
CONFIG_CONFIGGFS_FS=y

openais: whitetank
gfs2: devel.1166118689 from cvs

Many thanks,

Spencer
