manta: mount /MyDisk
manta:~ # mount /MyDisk
mount.nfs: requested NFS version or transport protocol is not supported
So i reproduced the same error without going through a suspend/resume sequence.
Also i created an ext4 file system on a USB stick on guppy, mounted and
exported it to manta.
On manta i saw the same "mount.nfs: requested NFS version or transport protocol
is not supported" error after a suspend/resume sequence. This was on the ext4
file system.
