Piotr has 10x10TB drives (yes, seriously) and wants to maximize usage of his space while still having protection against failures. ZFS is a great option for this – highly performant, very flexible, and solid code that’s been in production for a long time.
ZFS – the Zettabyte File System – was developed by Sun Microsystems back when they were still a thing. It started on Solaris and then as open sourced. For a long time there were licensing issues which is why early on it was available on *BSD systems but not Linux, but this is all a thing of the past now.
ZFS is 128-bit, which means it can store…well, a lot of data. To full populate a single storage pool would require 3×1024 TB drives.
Even Piotr doesn’t have that many.
Setting it all up on But it’s not as simple as it looks. Fortunately Piotr has a quick tutorial on how to use (or modify) a simple script to do all the heavy lifting for you.
