About  to  migrate  my  NAS  from mdraid + LVM + ext4 to ZFS on Linux.
  Let's see how well that works.

  I'd generally like to avoid all  the  hazzle  with  compiling  modules
  myself,  but  the  DKMS variant seems to work reasonably well (on Arch
  Linux).

  The main reason I'm doing this is for ZFS's data integrity checks  and
  recovery. That's really awesome.
