Managing Serviceguard Sixteenth Edition, March 2009

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.
For other restrictions, see “Unsupported Features” in the “Technical Overview” section
of the VERITAS Storage Foundation™ Cluster File System 4.1 HP Serviceguard Storage
Management Suite Extracts at http://docs.hp.com -> High Availability ->
HP Serviceguard Storage Management Suite.
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 thecfs commands, including cfsdgadm,
cfsmntadm, cfsmount, and cfsumount. Non-cfs commands could cause
conflicts with subsequent command operations on the file system or Serviceguard
packages.
NOTE: The disk group and mount point multi-node packages do not monitor
the health of the disk group and mount point. They check that the packages that
depend on them have access to the disk groups and mount points. If the dependent
application package loses access and cannot read and write to the disk, it will fail;
however that will not cause the DG or MP multi-node package to fail.
3. Verify with cmviewcl or cfsmntadm display. This example uses the
cfsmntadm command:
cfsmntadm display
