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 different nodes.

 To determine the primary file system in a cluster

# fsclustadm -v showprimary mount_point

 To determine that the current node is the master CVM node

# vxdctl -c mode

 To actually increase the size of the file system

  1. On the master CVM node, type the following command:

# vxassist -g shared_disk_group growto volume_name newlength

  1. On any SFCFS node, type the following command:

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