I exported everything rw. / -alldirs -maproot=root -network 192.168.0 -mask 255.255.255.0 /home -alldirs -maproot=root -network 192.168.0.0 -mask 255.255.255.0 Question: what is your /etc/exports? Did you export all rw or /home/diskless_ro ro? Thing is that it's tricky to have both rw and ro exports on the same partition.
