Anything going against picking RAID-Z as a software RAID on 2-4 equally large HDDs? also wanna add an SSD cache (or maybe i should give the SSD directly to applications that generate previews and thumbnails)

or use LVM or btrfs with RAID-5? little bit confused which option to pick, but i think i want something with striping and parity

@stellavie Specifically btrfs RAID 5 (i.e. on fs level, not btrfs on raid 5) is a big no no. Last I heard there were still data loss problems.

Have you considered software RAID via mdadm btw? Not saying it's better than fs level RAID – actually considering using that instead in the future – but it's a well established option.

@fugi so basically the sensible options are

- LVM Raid + any FS
- mdadm Raid + any FS

- ZFS Raid with ZFS

and the ZFS Raid has some cool features which the others don't have?

the only problematic thing i have found is that zfs is not in the kernel

@stellavie yeah, zfs brings its own hassles.

Regular btrfs raid (just not raid 5) should be fine too, just doesnt have native encryption last I checked
