<div class="">
Having just been burnt by BTRFS I would stick with XFS and
LVM/others.<br class="">
<br class="">
LVM will do disk replication or raid1. I do not believe that
raid3,4,5,6.. is supported.<br class="">
mdadm does support all the various raid modes and I have used it
quite reliably for years.<br class="">
You may want to look at the raid456 write-journal but that will
require an SSD or NVME deivce to be used effectively.<br class="">
