>From cloud-init perspective, we have seen this too in our CI/CD
integration runs on both GCP and Azure lunar daily images which allows
cloud-init to resize2fs /dev/root on first boot, but also re-invokes
resize2fs a second time to assert cloud-init can be re-run all boot
stages without having to reboot[1] This 2nd run of cloud-init invokes
resize2fs /dev/root a second time.
This failure is resize2fs a second time due to checksums is seen only on
Azure lunar daily images containing linux-azure=5.19.0.1010.9 and
e2fsprogs=1.47.0. e2fsprogs=1.47.0 was introduced in Azure daily lunar
images on image version 23.04.202303170 (image version 23.04.202303170
allows multiple calls to resize2fs /dev/root without checksum errors)
GCP: CI/CD runners in cloud-init also started failing jobs on Mar 17th as well,
presumably across the same image build update and introduction of
esfsprogs=1.47.0 in lunar.
Our internal daily test runners track this failure signal well from daily image
builds for Azure[2] and GCP lunar[3] giving us a good signal the the failure
symptom below. We can ensure
'cloudinit.subp.ProcessExecutionError: Unexpected error while running '
'command.\n'
"Command: ('resize2fs', '/dev/root')\n"
'Exit code: 1\n'
'Reason: -\n'
"Stdout: Couldn't find valid filesystem superblock.\n"
'Stderr: resize2fs 1.47.0 (5-Feb-2023)\n'
' resize2fs: Superblock checksum does not match superblock while '
'trying to open /dev/root\n'

Bug description:
Issue
resize2fs utility is used to resize the filesystem and is idempotent
in nature. But in the 5.15 kernel, successive execution of resize2fs
is returning error.
Reproduction step (on AWS):
Create an AWS instance with AMI ami-056a67ea1b8ffa0fc (Linux
5.15.0-1022-aws) in us-west-2 region and attach an EBS volume.
Format and mount the disk - sudo mkfs.ext4 /dev/xvdb, sudo mkdir -p
/mnt/ssd0, sudo mount /dev/xvdb /mnt/ssd0
Increase the size of EBS volume.
Run sudo resize2fs /dev/xvdb multiple times.
The first execution returns -
$ sudo resize2fs /dev/xvdb
resize2fs 1.45.5 (07-Jan-2020)
Filesystem at /dev/xvdb is mounted on /mnt/ssd0; on-line resizing required
old_desc_blocks = 2, new_desc_blocks = 3
The filesystem on /dev/xvdb is now 5242880 (4k) blocks long.
The following execution returns -
$ sudo resize2fs /dev/xvdb
resize2fs 1.45.5 (07-Jan-2020)
The filesystem is already 5242880 (4k) blocks long. Nothing to do!
When you run the same step on the latest image ami-0a1d6d351894df6cc
(Linux 5.15.0-1026-aws).
The first execution returns -
$ sudo resize2fs /dev/xvdb
resize2fs 1.45.5 (07-Jan-2020)
Filesystem at /dev/xvdb is mounted on /mnt/ssd0; on-line resizing required
old_desc_blocks = 2, new_desc_blocks = 3
The filesystem on /dev/xvdb is now 5242880 (4k) blocks long.
The following execution returns
$ sudo resize2fs /dev/xvdb
resize2fs 1.45.5 (07-Jan-2020)
resize2fs: Superblock checksum does not match superblock while trying to open
/dev/xvdb
Couldn't find valid filesystem superblock.
