Greetings,

Can someone confirm what RAID is used?
I thought I set ZFS RAID5 equivalent (RAIDZ2?), but it seems I did not.
I got two vdev consisting of 8 SAS drives total for now.

Code:
root@nhmucfs01[~]# zpool status
  pool: boot-pool
 state: ONLINE
status: Some supported and requested features are not enabled on the pool.
        The pool can still be used, but some features are unavailable.
action: Enable all features using 'zpool upgrade'. Once this is done,
        the pool may no longer be accessible by software that does not support
        the features. See zpool-features(7) for details.

Can someone confirm if this is correct? Thanks!

Boot pool is single disk, no RAID.

Data pool, nhmucfs01-vd01 is two RAIDZ1 vdevs.

RAIDZ1 is RAID5 equivalent (tolerates single disk failure) (sometimes just called RAIDZ with no number attached)
RAIDZ2 is RAID6 equivalent (tolerates two failures)
RAIDZ3 is RAID7 or whatever, tolerates three failures.

Your pool fault tolerance is minimum of its component vdev fault tolerances.
In your case, both vdevs are identical at RAIDZ1, and the pool overall is guaranteed to tolerate single disk failure.
