LinuxQuestions.org - FIle System / Mounting Help For New Partition

I've been asked to attach a new 100 GB partition to our database server and then mount the newly created ext4 partition to /var/lib/pgsql/ directory and set it to auto-mount in /etc/fstab/

I've created a primary single partition /dev/xvdf:

Code:

[root@db1 ~]# fdisk -l



Disk /dev/xvda1: 12.9 GB, 12884901888 bytes

255 heads, 63 sectors/track, 1566 cylinders

Units = cylinders of 16065 * 512 = 8225280 bytes

Sector size (logical/physical): 512 bytes / 512 bytes

I/O size (minimum/optimal): 512 bytes / 512 bytes

Disk identifier: 0x00000000





Disk /dev/xvda3: 939 MB, 939524096 bytes

255 heads, 63 sectors/track, 114 cylinders

Units = cylinders of 16065 * 512 = 8225280 bytes

Sector size (logical/physical): 512 bytes / 512 bytes

I/O size (minimum/optimal): 512 bytes / 512 bytes

Disk identifier: 0x00000000





Disk /dev/xvdf: 107.4 GB, 107374182400 bytes

255 heads, 63 sectors/track, 13054 cylinders

Units = cylinders of 16065 * 512 = 8225280 bytes

Sector size (logical/physical): 512 bytes / 512 bytes

I/O size (minimum/optimal): 512 bytes / 512 bytes

Disk identifier: 0x00000000

Here is my /etc/fstab:

Code:

#

LABEL=/                /              ext4    defaults,noatime        1  1

/dev/xvdf              /var/lib/pgsql  ext4    defaults                0  0

tmpfs                  /dev/shm        tmpfs  defaults                0  0

devpts                  /dev/pts        devpts  gid=5,mode=620          0  0

sysfs                  /sys            sysfs  defaults                0  0

proc                    /proc          proc    defaults                0  0

Now my confusion / questions are as follows:

1. Why is it not /dev/xvdf1 in my fdisk -l read out?
2. How do I label this partition? Do I use e2label command and if so, what should the label be?
