Formatting and Labeling a Partition mkfs and e2label

Once you have done with partitioning, you need to format the partition for use,. Unless it is a raw partition. The partition still does not have a file system. Create the file system mkfs command can be utilized

[root@RHEL01i ~]# mkfs -t ext3 /dev/sdb1 mke2fs 1.41.12 (17-May-2010) Filesystem label= OS type: Linux Block size=4096 (log=2) Fragment size=4096 (log=2) Stride=0 blocks, Stripe width=0 blocks 262944 inodes, 1050241 blocks 52512 blocks (5.00%) reserved for the super user First data block=0 Maximum filesystem blocks=1077936128 33 block groups 32768 blocks per group, 32768 fragments per group 7968 inodes per group Superblock backups stored on blocks: 32768, 98304, 163840, 229376, 294912, 819200, 884736 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. [root@RHEL01i ~]#

If the file system on the new partition is /dev/sda6 and you want to label it /work, use:

e2label /dev/sda6 /work

By default, the installation program uses the mount point of the partition as the label to make sure the label is unique. You can use any label you want. Afterwards, create a mount point (e.g. /work) as root. Add to /etc/fstab
As root, edit the /etc/fstab file to include the new partition using the partition's UUID. Use the blkid -L label command to retrieve the partition's UUID. The new line should look similar to the following:

UUID=93a0429d-0318-45c0-8320-9676ebf1ca79 /work ext3 defaults 1 2

The first column should contain UUID= followed by the file system's UUID. The second column should contain the mount point for the new partition, and the next column should be the file system type (for example, ext3 or swap). If you need more information about the format, read the man page with the command man fstab.

If the fourth column is the word defaults, the partition is mounted at boot time. To mount the partition without rebooting, as root, type the command:

mount /work
