/home/ring/RingFile 172.28.10.0/23(ro,async,no_root_squash)

删除了/etc/fstab里面的：
#172.28.10.89:/home/ring/RingFile/amr /home/ms/imp-4.3.6/voice/ebrs1 nfs ro 0
#172.28.10.90:/home/ring/RingFile/amr /home/ms/imp-4.3.6/voice/ebrs2 nfs ro 0

添加了rc.local
mount 172.28.10.89:/home/ring/RingFile/amr /home/ms/imp-4.3.6/voice/ebrs1
mount 172.28.10.90:/home/ring/RingFile/amr /home/ms/imp-4.3.6/voice/ebrs2
