The cephfs per-machine redundancy mode is usually the preferred configuration. i.e. usually avoids cramming everything into a single point of failure, buying specialty SAS cards, and poking at live raid arrays to do maintenance.

Seen too many people's TrueNAS/FreeNAS installs glitch up over the years to trust the zfs community edition as a sane production choice. ZFS certainly has improved, but Oracle is not generally known for their goodwill toward the opensource community. ;-)

I've never run TrueNAS/FreeNAS in proper production, but I have run it at home for over a decade and never lost data, despite generally running on old hardware, multiple drive failures, motherboards dying and power outages/lightning strikes.

Overall been very little fuzz for my home NAS system.

BTRFS seems to be maturing nicely, hopefully we can start using it for these types of workloads in the next few years.

BTRFS? you have to be joking... zfs despite its history, it has rarely achieved that level of silliness.
