Hello folks, New machine, new opportunity to get up to speed with the contemporary best practices for multiple disks on UEFI.
The behavior I'd like -- and, I suspect, the behavior we'd all like -- is the machine stays bootable and data is preserved if any disk fails. Specifically, what I'd like to do if a disk fails (or starts warning me of possible failure) is shut the machine down at my convenience, replace the disk, have it re-boot, and re-populate the new disk with data in the background. For data, BTRFS works well for my use case, has for some time, and has been tested on disks dying in the last few years. However, this is the first time I have a chance to deal with this for /boot on EFI partitions, which can't be put on BTRFS. So, what are folks doing these days to mirror /efi and /boot? Googling shows that Ubuntu can boot off RAID directly here, but Debian cant quite yet without manually rsync'ing directories. Anybody have a firm solution here? Cheers! -- Boyan Penkov
