Creating a new GPFS filesystem ?

[polani]

Guys

I need to create a new GPFS filesystem in a existing GPFS cluster ( used for RAC ) with newly added disks to system.

Here is my procedue , pls review and recommend any necssary changes:

1. execute mmncrsd on new disk ( hdisk5) with a a new failure group ( different from what previously used for existing GPFS filesystem)

2.mmcrfs /data2 /dev/data2 -F /tmp/gpfs/datadisk1.desc -B 512K -m 1-M 1 -r 1 -R 1 -Q no -n 16 -A no


I think , i have to do stop GPFS cluster , before execution of mmcrnsd and mmcrfs commands ? am i right ?

Pls advice ?
