$ mount -a
mount: wrong fs type, bad option, bad superblock on sfs-nas1.cn-north-1b.myhuaweicloud.com:/share-47904473,
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.
该错误是由于没有安装nfs-utils造成的,安装一下即可解决
yum install nfs-utils -y
