sudo mount -o vers=4,tcp -t nfs4 128.224.166.113:/ tmp
/buildarea1 *(async,rw,insecure,insecure_locks,no_root_squash,fsid=1)
这里的fsid=1在nfs文件系统里再mount nfs是必须要的
/nfs *(rw,sync,no_root_squash,no_subtree_check,fsid=0)
/nfs *(rw,sync,no_root_squash,fsid=0)
mount -o vers=3 127.0.0.1:/nfs /mnt -v
/nfs *(rw,sync,no_root_squash)
