Creating a File System and Mount Point Package
CAUTION Nested mounts are not supported: do not use a directory in a CFS file
system as a mount point for a local file system or another cluster file
system.

Overview” section of the VERITAS Storage Foundation™ Cluster File

1. Create a filesystem:
newfs -F vxfs /dev/vx/rdsk/logdata/log_files
version 6 layout
1-048576 sectors, 1048576 blocks of size 1024, log size
16384 blocks
largefiles supported
2. Create the cluster mount point:
cfsmntadm add logdata log_files /tmp/logdata/log_files
all=rw
Package name “SG-CFS-MP-1” is generated to control the
resource.
You do not need to create the directory. The command creates one on
each of the nodes, during the mount.
CAUTION Once you create the disk group and mount point packages, it is
critical that you administer the cluster with the cfs commands,
including cfsdgadm, cfsmntadm, cfsmount, and cfsumount. These
non-cfs commands could cause conflicts with subsequent command
operations on the file system or Serviceguard packages. Use of these
other forms of mount will not create an appropriate multi-node
package which means that the cluster packages are not aware of the
file system changes.
