Public bug reported: 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.
