Given the plans to make btrfs the default, I'll share some of my own recent experiences, hopefully this can make it easier for the next person
One issue I've come across is that a btrfs filesystem can only be used on hosts with the same page size as the host that created the filesystem E.g. x86-64 kernels have a 4k default page size but powerpc64le kernels have been compiled with the optional 64k page size. This impacts various distributions. If somebody creates some filesystems with the 4k parameter and then they migrate them to the powerpc64le host, they won't mount If they try to go the other way, the filesystems won't mount either There are other non-btrfs issues related to the 64k page size, for example, nouveau driver won't work either To make things easier for btrfs, could it be worthwhile changing the default page size from 64k back to 4k on default kernels for most ordinary users? _______________________________________________ devel mailing list -- devel@lists.fedoraproject.org To unsubscribe send an email to devel-le...@lists.fedoraproject.org Fedora Code of Conduct: https://docs.fedoraproject.org/en-US/project/code-of-conduct/ List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines List Archives: https://lists.fedoraproject.org/archives/list/devel@lists.fedoraproject.org
