Manual decrypt mount file

Hi Folks,

we restarted our Vault server and have the following issue:

Vault Version: 0.8.3
Sealing mechanism: Shamir
Storage: S3
Failure: failed to mount entry: path=foo/test/bar/ error=cannot mount under existing mount ‘foo/test/’

We found out that Vault need to mount foo/test/bar/ before foo/test/ but does it in the wrong oder in the mounts table.

I our idea is to change the mount table manually, is there any way to decrypt the mount table and change the values?
