我已经创建了一个共享文件夹/data01/分享在一台 Suse Gnu/Linux 上，还为主机（客户端）机器创建了条目/etc/出口 /data01/share 10.241.200.53（读写，同步，no_root_squash，no_subtree_check）。但我得到这个之后导出文件系统-a
exportfs: No options for /data01/share 10.241.200.53(rw,sync,no_root_squash,no_subtree_check) : suggest (sync) to avoid warning
exportfs: /etc/exports [2]: Neither 'subtree_check' or 'no_subtree_check' specified for export ":/data01/share 10.241.200.53(rw,sync,no_root_squash,no_subtree_check)".
Assuming default behaviour ('no_subtree_check').
NOTE: this default has changed since nfs-utils version 1.0.x
exportfs: Failed to stat /data01/share 10.241.200.53(rw,sync,no_root_squash,no_subtree_check): No such file or directory

只需将选项 subtree_check 添加到 /etc/exports 中，如下所示：
# cat /etc/exports
/views_raw 10.143.3.44(rw,sync,no_root_squash,subtree_check)
重新启动 NFS 服务
# systemctl restart nfs-server
# exportfs -av
