hi,

Im a newbie to Freenas and have just setup a FreeNAS-11.2-U4.1 server watching youtube videos. Had a spare pc lying around with 3 x 1TB Hdd and got 2gb memory. Have installed Freenas and setup shares and selected Raid1 striped to utilize all 3 disks for maximum space.
It is recommended to have minimum 8gb memory which i have to upgrade to, but currently the works seems to be getting done.

I need help in extending the space and have got 1TB hdd to add. Can i extend the volume by adding only one disk or it needs to be always equal to the number of installed disks ( i.e 3 installed ) Also i need to backup my data to an external usb hdd for which i will follow the method given by Luca.

Thnx
