Ubuntu 18.04 may well enable (under review) 64bit,metadata_csum by default, thereby creating ext4 filesystems that are not compatible with e2fsck on Ubuntu-16.04 LTS (or 14.04)?
This creates all sorts of problems for compatibility/portability of filesystems, for e.g.:- * dual-booting 18.04 and older LTS versions * "ext4 portable disks" do not work. * (notice also Ken's hwe-edge/lvm issue above too). I strongly support that Xenial gets a backport of e2fsprogs-1.43 (as requested) so that this compatibility-annoyance is ameliorated, at least. Debian have already done this, created a "jessie-backports" e2fsprogs=1.43.3-1~bpo8+1 Hopefully tytso can advise us on the best version of e2fsprogs to backport (18.04 currently has 1.43.9-2). -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1365874 Title: Ubuntu 12.04 LTS, 14.04 LTS, 16.04 LTS do not support ext4 metadata checksumming To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/e2fsprogs/+bug/1365874/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
