To create an OCFS2 file system that will be locally mounted and not associated with a cluster, use the following command:
#mkfs.ocfs2 -M local --fs-features=local -N 1[options]device
For example, create a locally mountable OCFS2 volume on
/dev/sdc1 with one node slot and the label
localvol:
# mkfs.ocfs2 -M local --fs-features=local -N 1 -L "localvol" /dev/sdc1
You can use the tunefs.ocfs2 utility to convert a local OCTFS2 file system to cluster use, for example:
#umount /dev/sdc1#tunefs.ocfs2 -M cluster --fs-features=cluster -N 8 /dev/sdc1
This example also increases the number of node slots from 1 to 8 to allow up to eight nodes to mount the file system.
For information about using OCFS2 with clusters, see Chapter 22, Oracle Cluster File System Version 2.
