I have recently installed Ubuntu 16.10 to my flash drive. When I tried to make fsck on it I can't do it from any current LTS Ubuntu versions - 12.04, 14.04, 16.04. The only one working solution was to scan from 16.10 live install media.
So I think there are two solutions: 1. support 'metadata_csum' feature on all current supported Ubuntu LTS versions. 2. remove 'metadata_csum' feature from 16.10 default install options. ** Summary changed: - Ubuntu 14.04 does not support ext4 metadata checksumming + Ubuntu 12.04 LTS and 14.04 LTS does not support ext4 metadata checksumming ** Tags added: precise trusty xenial ** Summary changed: - Ubuntu 12.04 LTS and 14.04 LTS does not support ext4 metadata checksumming + Ubuntu 12.04 LTS, 14.04 LTS, 16.04 LTS do not support ext4 metadata checksumming -- 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 ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
