Oracle10g Grid Computing with RAC
Chapter 5 - Preparing Shared Storage

Configure OCFS for Linux

Now, it is time to create the file systems by using the mkfs command:

mkfs.ocfs -F -b 128 -L /u01  -m /data/oracle/NYREP/u01     -u 23444 -g 252
-p 0775 /dev/sdd1
mkfs.ocfs -F -b 128 -L /u02  -m /data/oracle/NYREP/u02     -u 23444 -g 252
-p 0775 /dev/sdd5
mkfs.ocfs -F -b 128 -L /r01  -m /data/oracle/NYREP/r01     -u 23444 -g 252
-p 0775 /dev/sdd6
mkfs.ocfs -F -b 128 -L /arch -m /data/oracle/NYREP/archive -u 23444 -g 252
-p 0775 /dev/sdd7
**********  NOTES on the Format of the Command **********
# mkfs.ocfs -F -b 128 -L /u04 -m /u04 -u 1001 -g 1001 -p 0775
where the syntax for ocfstool is:
mkfs.ocfs -b block-size [-C] [-F] [-g gid] -L volume-label
-m mount-path [-n] [-p permissions] [-u uid] [-v] [-V] device
with the following options:
 -b Block size in kilo bytes
 -C Clear all data blocks
 -F Force format existing OCFS volume
 -g GID for the root directory
 -L Volume label
 -m Path where this device will be mounted
 -n Query only
 -p Permissions for the root directory
 -q quiet execution
For example, mkfs command creates file system:
[root@host-0001 ]# mkfs.ocfs -F -b 128 -L /u02  -m /data/oracle/NYREP/u02 
-u 23444 -g 252 -p 0775 /dev/sdd5
Cleared volume header sectors                 
Cleared node config sectors

Cleared vote sectors                       
Cleared bitmap sectors
