# createFS
|
||||
#
|
||||
# This script is used to create new FS on xCAT Service Node to hold the nim
|
||||
# resources. Currently it support AIX system, will support Linux later.
|
||||
#
|
||||
# By default, the new FS is created as 5G based on rootvg. But it can be
|
||||
# customized, the options are compatible with AIX crfs command.
|
||||
#
|
||||
# If we need to create multiple file systems, then we need to call "create_FS"
|
||||
# multiple times at the bottom of this script, passing it different parameters.
|
||||
#
|
||||
# For example:
|
||||
# FS1 = ("/install", "jfs2", "rootvg","" , "yes", "size=5G");
|
||||
# FS2 = ("/install", "jfs2", "datavg", "hdisk2 hdisk3", "yes", "size=5G frag=512 nbpi=1024");
|
||||
#
|
||||
# create_FS $FS1
|
||||
# create_FS $FS2
|
||||
#
|
||||
#-----------------------------------------------------------------------------
|
||||
|
||||
# For AIX system
|
||||
# MountPiont, VfsType, VolumeGroup, harddisks, AutoMount, Attributes
|
||||
FS1="/install,jfs2,rootvg,,yes,size=5G"
|
||||
#FS2="/install,jfs2,datavg,hdisk2 hdisk3,yes,size=5G frag=512 nbpi=1024"
|
||||
|
||||
# To-DO
|
||||
# For Linux system
|
||||
# MountPiont, VfsType, fs-options
