Though I can shut it down at times. Once you've physically installed the disk and rebooted the system, you'll need to do the following: - Identify the disk. Use the "dmesg" command and/or the /var/log/dmesg and /var/log/messages files to identify the device special file associated with the new disk. It'll probably be /dev/sdb or /dev/sdc. - Partition the disk. Use the "fdisk" command to partition the new disk. Invoke the utility as follows: fdisk /dev/sdc replacing "/dev/sdc" with the name of the device special file corresponding to the new disk. If you would like to put a swap partition on the new disk, you'll need to assign the new swap partition the appropriate partition type. After partitioning the disk, save the changes to the partition table and exit the "fdisk" utility. - Format the new partitions. Use the "mke2fs" command to format the newly-created partitions: mke2fs -v /dev/sdc1 replacing "/dev/sdc1" with the name of the device special file corresponding to the partition to format. "/dev/sdc1" refers to the first partition on /dev/sdc. Format each new partition that is to contain a file system. - Create mount points for the new file systems. Use the "mkdir" command to create directories where the new file systems will be mounted. For instance, if you want one of the new file systems to be accessible as /home2, do: mkdir /home2 - Add entries for the new file systems in /etc/fstab. See the fstab(5) man page for more information on the format of /etc/fstab. See the mount(8) man page for more information on available mount options. - Mount the new file systems. That's it. ===
