#Check what you already have mounted in the system by entering the command "df". Several things will be listed but we are only interested in the "/volume" entries in the very right hand column of the table that is displayed. Everyone should have "/volume1" and depending on how you have your current disks configured you could have "/volume2", "/volume3" etc etc. take note of the last volume number and hence the next free volume number. In my case I had a "/volume1" but NOT "/Volume2". Hence for me "/Volume2" was not being used and this is where this example will load the new drive. If you have "/volume2" or more in your system you need to use the next free volume for all commands given below. | #Check what you already have mounted in the system by entering the command "df".

#Now we check that the new drive is being recognised, enter the command "fdisk -l" thats a lower case L not a 1. You will see each installed disk listed and each partition on the disk listed, e.g. Disk1 will be shown as "/dev/sda", with disk2 as "/dev/sdb", disk3 (if you have one) as "/dev/sdc" etc. Disk1 being a synology formated disk will have 3 partions shown as "/dev/sda1", "/dev/sda2" and "/dev/sda3". In my case the disk I added was disk2, hence is shown as "/dev/sdb". The disk I added ("/dev/sdb") was also a synology formated disk and hence has partitions "/dev/sdb1", "/dev/sdb2" and "/dev/sdb3".

#Now we need to map the data partion to a directory on the NAS root "/". For windows users the Linux "mount" command makes data on the mounted partition appear in a directory in the operating system root directory. Before we can mount the drive we have to create the directory the mounted drive will be attached to. From the step above the next free volume number I had was "/volume2".

For the example above, i.e. we want to mount disk2, you will need to add an entry like "/dev/hdb /volume2 ext3 defaults 0 0" where the "b" of "hdb" represents disk2, "hdc" would be disk3 and "hdd" disk4, etc. If you need help using vi see [[Linux VI Editor|Basic commands for Linux VI Editor]]. Note in the fstab file we are describing the format and way we want the OS to handle the disk, so you don't specify the partition numbers. After modifying the fstab file. You use different options in the mount command, i.e. without the "-t" and "ext3" options. Hence enter something like "mount /dev/hdb3 /volume2" making sure you use the exact correct nomenclature for your circumstances as described previously. | ||
