Comment 18 for bug 2003816

The issue is also present in Jammy distro kernel (linux-image-5.15.0-67-generic) and e2fsprofs 1.46.5-2ubuntu1.1

How to reproduce :
* Create an openstack instance and user virtio-scsi as block device controller
* Add a Cinder volume (backed by PureStorage/iSCSI)
* format the whole volume : mkfs.ext4 /dev/sdb
* mount it somewhere : mount /dev/sdb /mnt/test
* resize volume from Cinder, check with lsblk that the volume is properly expanded
* online resize the volume without unmounting it : resize2fs /mnt/test

It works but doing it a second time fails most of the time with the "Superblock checksum does not match superblock" error.
Unmounting and doing a fsck fix the problem easily but the "online" feature is severely degraded if you need to do things offline ...
