[Bug 1798562] Please test proposed package

[Brian Murray]

Hello Jean-Baptiste, or anyone else affected,

Accepted e2fsprogs into bionic-proposed. The package will build now and
be available at
https://launchpad.net/ubuntu/+source/e2fsprogs/1.44.1-1ubuntu1.1 in a
few hours, and then in the -proposed repository.

Please help us by testing this new package.  See
https://wiki.ubuntu.com/Testing/EnableProposed for documentation on how
to enable and use -proposed.  Your feedback will aid us getting this
update out to other Ubuntu users.

If this package fixes the bug for you, please add a comment to this bug,
mentioning the version of the package you tested and change the tag from
verification-needed-bionic to verification-done-bionic. If it does not
fix the bug for you, please add a comment stating that, and change the
tag to verification-failed-bionic. In either case, without details of
your testing we will not be able to proceed.

Further information regarding the verification process can be found at
https://wiki.ubuntu.com/QATeam/PerformingSRUVerification .  Thank you in
advance for helping!

N.B. The updated package will be released to -updates after the bug(s)
fixed by this package have been verified and the package has been in
-proposed for a minimum of 7 days.

Title:
  After a side by side installation, resized filesystem is corrupted

Status in e2fsprogs package in Ubuntu:
  Fix Released
Status in e2fsprogs source package in Bionic:
  Fix Committed
Status in e2fsprogs source package in Cosmic:
  Fix Committed

Bug description:
  [Impact]
  - Users resizing filesystems using resize2fs.
  - Resizing an existing Linux filesystem from the Ubuntu installer.

  [Test cases]

  Test Case 1:
  With e2fsprogs 1.44.4-2:

  Download this file system image:
  https://bugs.launchpad.net/ubuntu/+source/e2fsprogs/+bug/1798562/+attachment/5203159/+files/vda1b.qcow2.bz

  Run the following commands:

  bunzip2 vda1b.qcow2.bz
  qemu-img convert vda1b.qcow2 vda1b.raw
  e2fsck -f vda1b.raw
  resize2fs vda1b.raw 6200M
  e2fsck -f vda1b.raw

  e2fsck 1.44.4 (18-Aug-2018)
  Pass 1: Checking inodes, blocks, and sizes
  Inode 45746 extent block passes checks, but checksum does not match extent
          (logical block 1272, physical block 466167, len 776)
  Fix<y>?

  Test Case 2 (Use case of the installer):
  1. Perform a first installation of Ubuntu
  2. Reboot into the freshly installed system and verify everything works as expected
  3. Do a second installation and select "Install alonogside". Keep the size proposed by the installer and proceed to the end of installation
  4. Reboot
  5. On boot, in the list of installed systems, select the first system installed on the machine
  6. Verify that it boots, you can login and it works as expected

  Actual Result
  The FS is corrupted and depending on the corruption it goes to initramfs, boots but cannot login, ...

  
  [Regression potential]
  This changes behavior in the update logic for extent blocks; as such, care should be taken to make sure that testing takes into account the possibility to introduce filesystem corruption while resizing. This is why the test cases include running e2fsck as last step.
