You want to read, at a minimum:

https://pthree.org/2012/12/04/zfs-administration-part-i-vdevs/

It may be 8 years old, but it's substantially still correct.

Thanks for that. Is it simply a case of installing the DKMS module,
building the pool (two drives in my case), formatting and mounting?

- data integrity
- snapshots and zfs send/receive for backups
- good reporting of disk events
- does not incur an unacceptable speed penalty
- well documented, relatively simple method of disk replacement
- pools can be transferred between machines without specific
  controller requirements
- flexibility of filesystems-on-pools

And because I have that experience at work, I am reasonably
happy to run it at home on the systems where it makes sense.

Yes, on a largish number of servers plus a few desktops and a
laptop.


And a follow up, why do you use it?
