/usr/sbin/cluster/sbin/cl_crfs -cspoc “-ncws,pci” -v jfs2 -gconvg -a size=32786 -m/test-export -prw -a size=4096
In the above command –n for nodes here pci and cws are nodes
-v for type of file system –g for vgname
-m for mount point
-p for permissions
-a size is size in blocks
EXTENDING A FILE SYSTEM IN HACMP
# /usr/es/sbin/cluster/sbin/cl_chfs -cspoc "-g testrg" -a size=+32768 /shfs
cws: File System size changed to 65536

MOVE THE RG TO OTHER NODE AND VERIFY FILE SYSTEM
# /usr/es/sbin/cluster/utilities/clRGmove -g testrg -n pci -m
