Growing a CFS file system
There is a master node for Cluster Volume Manager (CVM) as well as a primary node for the Cluster File System (CFS). When growing a file system, you grow the volume and slaves from the CVM master, and then grow the file system from any CFS node. The CVM master and the CFS node can be different nodes.
To determine the primary file system in a cluster
To determine that the current node is the master CVM node
- To determine if the current node is the master CVM node, type the following comannd:
# vxdctl -c mode
To actually increase the size of the file system
- On the master CVM node, type the following command:
# vxassist -g shared_disk_group growto volume_name newlength
- On any SFCFSHA node, type the following command:
# fsadm -t vxfs -b newsize -r device_name mount_point
