Comment on Server for a boat
HumanPerson@sh.itjust.works 4 months agoThey said they want a local backup so they don’t have to redownload because bandwidth is expensive. I think a RAID makes more sense. I also don’t think btrfs is a great idea for a boat. Power failures will probably be somewhat common, and btrfs is not the most stable, so I don’t think I would trust it in weird conditions. Documentation is definitely a great idea though.

BTRFS should be stable in the case of power loss. That is to say, (it ought to recover to a valid state)[unix.stackexchange.com/…/does-btrfs-guarantee-dat…]. I believe the only unstable modes are RAID 5/6.
I’d recommend BTRFS in RAID1 mode over mdadm RAID1 + ext4. You get checksumming and scrubs to detect drive failures and data corruptions. You also have snapshotting, in case you’re prone to the occasional fat-fingered
rm -rf.
