I have a system with several hard drives that I want to put into a pool and use as a storage area (vm images, plex, backups, etc.)
Previously, I've used BTRFS, but I've looked at zfs and am currently torn between the two.
But that's an issue for another time.
For storage pools, would you recommend having the OS stored in the pool, or outside?
For example,
2 hard drives raid1 with nothing but the OS, and the rest of the disks can be set up however (probably going to be raid60)
or,
all hard drives set up raid60 with the host OS inside, and the data areas managed using quotas so the OS isn't starved of space.
