ZFS appears to be unrelated to your problem. It sounds like you're
trying to mount fdescfs from within a jail. That's not allowed by
default. Is your VPS itself a jail? If so, you'll have to ask your
hosting provider to set allow.mount.fdescfs=1 in your jail config. Or
are you trying to use nested jails? If so, set that same parameter in
the config for your outer jail.
