I'm new to OMV and discovered it while looking into FreeNAS. Great system and wonderful GUI! Love it.
When setting up my first NAS disk array, I struggled to determine if I should go with EXT4 or ZFS. I went with ZFS because it seems like it had more redundancy baked in. I have a 6 disk x 2T system, so I'm getting approx 4 x 2T of space (7.2T space actually).
Everything is working great so far. Are there any periodic tools & disk checks I can use to verify that things are running on a weekly or monthly basis? SMART is enabled on all disks.
