That was the question I posed several posts back: what do people do for redundant ESP. > When you don't use btrfs, you have either hardware RAID or > mdraid. …or zfs or bcachefs or no redundancy at all… > With mdadm RAID, it isn't much better than with btrfs since > without further ado, you still don't have redundant UEFI > partitions. As mentioned, people do try it, and we don't yet have any reports of catastrophe. I'm not sure I am brave enough though. > With btrfs and mdadm RAID, it's basically worse because you have > to deploy another variant of software RAID in addition to the > software built into btrfs. I see, so this is basically a philosophical objection. You already have software that provides redundancy (btrfs), but since UEFI firmware can't read it and insists that ESP be vfat, it would mean providing redundancy another way. This need to have two means of redundancy is an affront to you. In practical terms, having md driver just for a small ESP array is not going to be a big deal, but just the idea of configuring this extra form of redundancy, having that extra driver loaded etc., is unpleasant. > So at least for boot disks, I'll go for hardware RAID whenever > possible, especially with btrfs, until this problem is fixed. Or do > you have a better option? Right, so your answer is hardware RAID. If you're happy with that, that's great, but I've left hardware RAID behind nearly ten years ago and this issue isn't enough for me to welcome it back. Though it leaves a bad taste, I still would rather go with either syncing ESPs by script or putting ESP in MD RAID and hoping firmware never write to it. I just wondered if there were more options (yet). Thanks, Andy -- https://bitfolk.com/ -- No-nonsense VPS hosting
