[Bug 1365874] Re: Ubuntu 12.04 LTS and 14.04 LTS does not support ext4 metadata checksumming

[Norbert]

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

Title:
  Ubuntu 12.04 LTS, 14.04 LTS, 16.04 LTS do not support ext4 metadata
  checksumming

Status in e2fsprogs package in Ubuntu:
  In Progress

Bug description:
  In the Trusty release notes "Metadata checksumming" is listed as one
  of the tech highlights of kernel 3.13.

  https://wiki.ubuntu.com/TrustyTahr/ReleaseNotes#New_features_in_14.04_LTS

  However, the userland tools do not support this kernel feature. To the
  best of my knowledge this will be supported in 1.43, and won't be
  backported to 1.42.

  IMHO this is very misleading. It's like a car salesperson sold you a
  sports car with an V8 engine. After you drove it home, you opened the
  hood and realized only 6 cylinders are working because 2 of the spark
  plugs were not included, and you have to buy aftermarket ones.

  <rant>BTW, I've been following the development of e2fsprogs for over a
  year. 1.43  release has been in limbo for God knows how long :(
