The mount and fsclustadm commands are also important for configuring cluster file systems.
The mount command with the -o cluster option lets you access shared file systems.
See the mount_vxfs(1M) manual page.
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.
The fsadm command can be invoked from the primary or secondary node.
See the fsadm(1M) manual page.
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 as dd execute without any reservation, and can damage a file system mounted from another node. Before running this kind of command on a file system, be sure the file system is not mounted on a cluster. You can run the mount command to see if a file system is a shared or local mount.
