问题描述
在阿里云ECS服务器上挂载阿里云NAS服务，报错
    [root@ips-db-yanl ~]# sudo mount -t nfs -o vers=3,nolock,proto=tcp,rsize=1048576,wsize=1048576,hard,timeo=600,retrans=2,noresvport 11b9a4bb32-ehv60.cn-beijing.nas.aliyuncs.com:/ips /nas_ips
    mount: wrong fs type, bad option, bad superblock on 11b9a4bb32-ehv60.cn-beijing.nas.aliyuncs.com:/ips,
           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.
    [root@ips-db-yanl ~]#
