I did partition /dev/sda1 using fdisk.

After creating two partitions, saved the table. And rebooted the server. But there is no device file present for new partitions.

:~$ sudo fdisk -l 

Disk /dev/sda: 32.2 GB, 32212254720 bytes

:~$ sudo fdisk -l /dev/sda1

Partition table entries are not in disk order

I am using Ubuntu 12.4 linux on VMPlayer.

  • Thanks for the added info. How did you create the new partitions? – Eliah Kagan Apr 6 '13 at 19:20
