However, because we have people who have Leap 42.1 and current Tumbleweed installed, we can’t just switch from 64k to 4k PAGE_SIZE, because our friend btrfs embeds the page size into its on-disk format and can only read it when they’re identical. So switching would break existing btrfs installations.
The page size is used automatically at the mkfs time and stored independently as 'sectorsize'. The on-disk format does not depend on any runtime variables, it's the other way around (ie. runtime must support the on-disk values). -- To unsubscribe, e-mail: opensuse-arm+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-arm+owner@opensuse.org
