Yes, I did.

I wanted all storage in the vgcomp group but I wanted each to be on it's own 
and not contiguous. 
So I did;

gfs_mkfs -p lock_dlm -t vgcomp:gfscomp -j 16 /dev/vgcomp/rimfire
gfs_mkfs -p lock_dlm -t vgcomp:gfs -j 16 /dev/vgcomp/str1

Now, I can only mount one or the other and not both. If I try to mouth both, I 
get the errors I posted. I'll repost the errors so it's all in one msg.

# mount -t gfs /dev/vgcomp/str1 /lvstr1
mount: File exists
