mount, fsclustadm, and fsadm commands
The mount and fsclustadm commands are important for configuring cluster file
systems.
mount
The mount command with the -o cluster option lets you access shared file
systems.
See the mount_vxfs(1M) manual page.
fsclustadm
The fsclustadm command reports various attributes of a cluster file system.
Using fsclustadm you can show and set the primary node in a cluster, translate
node IDs to host names and vice versa, list all nodes that currently have a cluster
mount of the specified file system mount point, and determine whether a mount
is a local or cluster mount. The fsclustadm command operates from any node in
a cluster on which the file system is mounted, and can control the location of the
primary for a specified mount point.
See the fsclustadm(1M) manual page.
fsadm
The fsadm command can be invoked from the primary or secondary node.
See the fsadm_vxfs(1M) manual page.
Run commands safely in a cluster environment
Any UNIX command that can write to a raw device must be used carefully in a
shared environment to prevent data from being corrupted. For shared VxVM
volumes, SFCFS provides protection by reserving the volumes in a cluster to
prevent VxFS commands, such as fsck and mkfs, from inadvertently damaging
a mounted file system from another node in a cluster. However, commands such
