[TriLUG] ZFS and hardware raid question

[Ron Kelley]

I went through the same exercise recently and found the "best practice" is not to use hardware RAID.  However, ZFS certainly can work with hardware RAID but you won't get the extra benefits of low-level disk stuff (scrubbing, etc).  When using hardware RAID, ZFS is just an enhanced filesystem manager (dynamic pools, compression, etc).

Just use the disks as separate devices (i.e. let ZFS see 6 disks) then setup Raid-z2 and ZFS handles everything.  Is that correct?
