[Bug 1778140] Re: resize2fs hoses a filesystem on lvm after resizing

[Theodore Ts'o]

#1  Was this an on-line or off-line resize?   That is, was the file
system mounted at the time when you ran resize2fs?

#2   Can you post a copy of dumpe2fs before you started to resize?

#3   How big were you trying to resize the file system to become?

It's great that you have a snapshot of the file system pre-resize, since
that means we can test potential fixes.  If you can keep a snapshot of
that exist file system image while I investigate this failure, it would
be much appreciated.

Title:
  resize2fs hoses a filesystem on lvm after resizing

Status in e2fsprogs package in Ubuntu:
  New

Bug description:
  Resized an ext4 filesystem on LVM. Before resizing, I confirmed
  filesystem was clean with e2fsck. After resizing, three errors were
  found.

  root at ubuntu:~# e2fsck -f /dev/ubuntu-vg/root
  e2fsck 1.44.1 (24-Mar-2018)

  This setup is currently in a virtual machine with a snapshot, so I can revert back and retest. The resize2fs is coming from the 18.04 Ubuntu CD.
