  KFOD(Kernel Files Osm Disk)用來從作業系統層面模擬disk discovery。該工具可以從$GRID_HOME/bin目錄（或者是老版本的ASM_HOME/bin目錄）下找到。

注意：
1).KFOD也會在安裝時使用（透過OUI，DBCA或者ASMCA），為了執行disk discovery。
2).在失敗安裝的情況下（例如，$GRID_HOME/bin不存在），KFOD能在stage資料夾下找到：/grid/stage/ext/bin/，同時需要設定LD_LIBRARY_PATH到/grid/stage/ext/lib

1.KFOD幫助資訊：
[root@rhel1 ~]# su - grid
[grid@rhel1 ~]$ which kfod
/u01/app/11.2.0/grid/bin/kfod
[grid@rhel1 ~]$ kfod -help
_asm_a/llow_only_raw_disks KFOD allow only raw devices [_asm_allow_only_raw_disks=TRUE/(FALSE)]
_asm_l/ibraries ASM Libraries[_asm_libraries=lib1,lib2,...]
_asms/id ASM Instance[_asmsid=sid]
a/sm_diskstring ASM Diskstring [asm_diskstring=discoverystring, discoverystring ...]
c/luster KFOD cluster [cluster=TRUE/(FALSE)]
db/_unique_name db_unique_name for ASM instance[db_unique_name=dbname]
di/sks Disks to discover [disks=raw,asm,all]
ds/cvgroup Include group name [dscvgroup=TRUE/(FALSE)]
g/roup Disks in diskgroup [group=diskgroup]
h/ostlist hostlist[hostlist=host1,host2,...]
metadata_a/usize AU Size for Metadata Size Calculation
metadata_c/lients Client Count for Metadata Size Calculation
metadata_d/isks Disk Count for Metadata Size Calculation
metadata_n/odes Node Count for Metadata Size Calculation
metadata_r/edundancy Redundancy for Metadata Size Calculation
n/ohdr KFOD header suppression [nohdr=TRUE/(FALSE)]
o/p KFOD options type [OP=DISKS/CANDIDATES/MISSING/GROUPS/INSTS/VERSION/CLIENTS/RM/RMVERS/DFLTDSTR/GPNPDSTR/METADATA/ALL]
p/file ASM parameter file [pfile=parameterfile]
s/tatus Include disk header status [status=TRUE/(FALSE)]
v/erbose KFOD verbose errors [verbose=TRUE/(FALSE)]

2.使用kfod例子：
[grid@rhel1 ~]$ kfod status=TRUE asm_diskstring='/dev/raw/raw*' disks=all
