If these commands have been entered in the order you posted them then you indeed seem not to understand what disks, volumes, partitions and filesystems are. You might profit from reading this little introduction i once wrote. This was for AIX, but the Linux LVM was built after the AIX LVM and the concepts are absolutely the same - just the commands are a little bit different.

I hope this helps.

mounted.ocfs2

mounted.ocfs2(8)						OCFS2 Manual Pages						  mounted.ocfs2(8)

NAME

       mounted.ocfs2 - Detects all OCFS2 volumes on a system.

SYNOPSIS

       mounted.ocfs2 [-d] [-f] [device]

DESCRIPTION

       mounted.ocfs2  is used to detect OCFS2 volume(s) on a system.  This tool assumes that the nodes detected on the system are part of the same
       cluster as the one specified in /etc/ocfs2/cluster.conf.

OPTIONS

       -d     Lists the OCFS2 volumes along with their labels and uuids.  If a device is not specified, it scans all the devices  in  /proc/parti-
	      tions.

       -f     Lists  the OCFS2 volumes along with the list of nodes that have mounted the volume. The node names are listed if the O2CB cluster is
	      online. Note: As this information is gathered using dirty-read, the information may be stale.

EXAMPLES

       [root@node1 ~]# mounted.ocfs2 -d
       Device	   FS	  Stack  UUID				   Label
       /dev/sdb1   ocfs2  local  2D1C9636FE38462DB43A75D1DA592207  vmvol
       /dev/sdj1   ocfs2  o2cb	 FF2E239B02D941FEAF25BDAE8DD553B9  dbstore

       [root@node1 ~]# mounted.ocfs2 -f
       Device	   FS	  Nodes
       /dev/sdb1   ocfs2  node15, node1
