权限什么的都加上了,提示如下:
[root@iZbp1fw31uh95mtrgc211eZ ~]# sudo mount -t nfs -o vers=4 020b148ae8-uck5.cn-hangzhou.nas.aliyuncs.com:/ /mnt
mount: wrong fs type, bad option, bad superblock on 020b148ae8-uck5.cn-hangzhou.nas.aliyuncs.com:/,
missing codepage or helper program, or other error
(for several filesystems (e.g. nfs, cifs) you might
need a /sbin/mount.<type> helper program)
In some cases useful info is found in syslog - try
dmesg | tail or so
