>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.

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.
