This provides the fastest read and write speeds but it offers no redundancy. In a two disk striped array, half of a file would be on disk one and half of the file on disk two. Stripe – data will be stored across all available disks, equivalent to RAID 0.For example, if you use 2x 500GB disks, only 500GB will be available as the other 500GB will be a copy of the first disk. This provides the best redundancy but requires the most space. You require a minimum of two disks for a mirrored set. This is quite simply a copy of one disk to another every time data is changed. Mirror – data will be mirrored across disks, equivalent to RAID 1.Disks can be combined into virtual groups to allow for various redundancy options: ZFS provides a data volume which can have multiple mount points, spanning multiple disks.

We can now install the ZFS on most Linux distributions such as Debain/ Ubuntu and Red Hat/ CentOS. Thanks to some clever guys over at ZFS on Linux, this has now changed. You an remove this option if you don’t think it’s a good fit for you.ZFS was initially developed by Sun for use in Solaris and as such was not available on Linux distributions. This should increase performance, but at the cost of total storage space. I’m using drives with 4k physical sectors, so I’m adding the option: -o ashift=12 If your setup is like mine, you’ll create one pool with many volumes in it. In my example below, I’m naming my pool “data.” You can use a different name if you’d like. This is where SSH is handy, since you can copy/paste your paths from above. I’ll be using sdb for the ZIL, sdc for L2ARC, and sdd, sde, sdf, sdg, and sdh to for the data pool.įirst, I’ll setup the data pool. I chose to install Linux on my 1st drive (sda). You’ll want to be able to copy and paste when you setup the zpool. SSH Into the server, rather than using the console. Perform a regular Ubuntu server installation, or use an existing server. If you’re planning something enterprise-grade, find an expert! Install Ubuntu From what I’ve gleaned, this should suffice for home / small business use. Quick disclosure: I’m *far* from a ZFS expert.

Welcome to Part II of my Ubuntu Home Server build! In Part I, I did a very basic Ubuntu Server install.
