Partitioning with fdisk

[root@rac1 ~]# fdisk /dev/sdh
Device contains neither a valid DOS partition table, nor Sun, SGI or OSF disklabel
Building a new DOS disklabel. Changes will remain in memory only,
until you decide to write them. After that, of course, the previous
content won't be recoverable.


The number of cylinders for this disk is set to 6527.
There is nothing wrong with that, but this is larger than 1024,
and could in certain setups cause problems with:
1) software that runs at boot time (e.g., old versions of LILO)
2) booting and partitioning software from other OSs
   (e.g., DOS FDISK, OS/2 FDISK)
Warning: invalid flag 0x0000 of partition table 4 will be corrected by w(rite)

Creating an ext3 filesystem

[root@rac1 ~]#  mkfs -t ext3 /dev/sdh1
mke2fs 1.39 (29-May-2006)
Filesystem label=
OS type: Linux
Block size=4096 (log=2)
Fragment size=4096 (log=2)
6553600 inodes, 13107024 blocks

First data block=0
Maximum filesystem blocks=4294967296

        4096000, 7962624, 11239424

Writing inode tables: done                            
Creating journal (32768 blocks): 
done
Writing superblocks and filesystem accounting information: 
done

This filesystem will be automatically checked every 20 mounts or
180 days, whichever comes first.  Use tune2fs -c or -i to override.


Create a mount point:
[root@rac1 u01]# mkdir /u01


Edit the /etc/fstab to include the new partition
# vi /etc/fstab
Append the new line as follows:
/dev/sdh1 /u01 ext3 defaults 1 2 

Mount the filesystem

[root@rac1 u01]# mkdir /u01
