It happens in VE0. mtab is a file an contains:

aipaddr:/pve/0.9 /pve/0.9 nfs rw,addr=XXX.XXX.XXX.XXX 0 0

But remount rw fails:

> mount -o ro,remount /pve/0.9/
mount: /pve/0.9 not mounted already, or bad option

Strace says:

mount("aipaddr:/pve/0.9", "/pve/0.9", 0x517c10, MS_MGC_VAL|MS_RDONLY|MS_REMOUNT, "\6") = -1 EINVAL (Invalid argument)
