how to create a new filesystem in REDHAT Linux
fdisk /dev/sda
enter n to create new partition.
enter the size of the partition.
enter “w” to write the partition table and restart the system if required.
2) Format the partition for the filesystem.
/sbin/mkfs -t ext3 /dev/sda11
[root@node3 ~]# /sbin/mkfs -t ext3 /dev/sda11
mke2fs 1.39 (29-May-2006)
Filesystem label=
OS type: Linux
Block size=4096 (log=2)
Fragment size=4096 (log=2)
3260416 inodes, 6516365 blocks
325818 blocks (5.00%) reserved for the super user
First data block=0
Maximum filesystem blocks=4294967296
199 block groups
32768 blocks per group, 32768 fragments per group
16384 inodes per group
Superblock backups stored on blocks:
32768, 98304, 163840, 229376, 294912, 819200, 884736, 1605632, 2654208,
4096000
Writing inode tables: done
Creating journal (32768 blocks): done
Writing superblocks and filesystem accounting information: done
This filesystem will be automatically checked every 33 mounts or
180 days, whichever comes first. Use tune2fs -c or -i to override.
3) Give a label to the partition
[root@node3 ~]# /sbin/e2label /dev/sda11 /oradisk
4) Add an entry in the /etc/fstab to make the filesystem mount on every reboot.
LABEL=/oradisk /oradisk ext3 defaults 1 2
5) Mount the new filesystem
[root@node3 ~]# mkdir /oradisk
[root@node3 ~]# chown oracle:oinstall /oradisk
[root@node3 ~]# mount /dev/sda11 /oradisk
[root@node3 ~]# df -h
