With FUSE-T and latest 1.7.2 I can no longer add data to vaults. Shows 0 bytes free.
you are not the only user with this problem. There exists already a ticket on our bug tracker:
Workaround is currently only a change of the volume type to WebDAV (unstable in MacOS) or a downgrade to 1.6.17
Its a cold vault so I will wait for the next release.
Thanks a lot
