Hi team, I got a old machine with four hard drivers. I want to install Ubuntu and run fog server on it. And I want to use all four hard drivers for the storage. I am installing Ubuntu in one of the hard driver, and try to create a storage pool for fog server using the other three hard drivers. Do I need to create a storage pool for fog server? I mean if I did not create the storage pool, will fog server still use the other three drivers for storage? What I learned from Internet is to create a RAIDZ ZFS storage pool. I am not sure if it gonna work or not.

If your old computer is a server with a physical raid card, that is your easiest solution. If you don’t have a hardware raid card then it gets a little more complicated. You can either setup a software raid using mdadm in ubuntu. If you don’t care about data loss you can setup a raid-0 configuration to stripe all of the drives. If you do care about data loss then use raid-1 (2 drives) or raid-5 (3 drives with 2 data drives and one parity drive). then mount that raid volume to /images (before fog is installed) You can also use LVM and add the 3 drives to the LVM pool where the root directory is mounted. Again this approach doesn’t protect against data loss of a single disk. There are a number of ways to go about it some easier than others.
