Prepare new hard disk
  • To export a brand new disk through nfs, the corresponding device in the /dev directory must be find (use the boot log messages from /var/log). Lets assume that the new device is /dev/hdg.
  • Create the new partition on your disk with the command: fdisk /dev/hdg. Follow the instructions and create one big partition /dev/hdg1.
  • Format the new partition with the ext3 file system with the following command: mkfs -t ext3 -c /dev/hdg1 ("-c" options search for invalid disk sectors).
  • Create the new export directory (/srv/nfs) and change the permission to 1777 and mount the partition on it.
  • The new device will be mounted on boot on the selected directory.
