EBS won’t mount, bad superblock

Creating a volume from a snapshot preserves the file system uuid.

If you try to mount 2 of these drives on the same instance, you can run into problems with the duplicate uuids.

mount: wrong fs type, bad option, bad superblock on /dev/sdi,
missing codepage or other error

Taking a look at dmesg tells you the following:

XFS: Filesystem sdi has duplicate UUID – can’t mount

The mount command has a nouuid option you can use to work around this.

Alternatively, you can just unmount the existing drive, and then mount the new one if you are just trying to replace a drive.
