Growing a Storage Foundation Cluster File System

There is a master node for CVM as well as a primary for SFCFS. When growing a file system, you grow the volume from the CVM master, and then grow the file system from any SFCFS node. The CVM master and the SFCFS node can be two different nodes.

To determine the primary file system in a cluster, enter:

# fsclustadm -v showprimary mount_point

To determine if the current node is the master CVM node, enter:

# vxdctl -c mode

To actually increase the size of the file system, run the following two commands. On the master CVM node, enter:

# vxassist -g shared_disk_group growto volume_name newlength

On any SFCFS node, enter:

# fsadm -t vxfs -b newsize -r device_name mount_point
