NFS客户端mount挂载深入

1. NFS客户端mount挂载参数说明

NFS服务端可以通过 cat /var/lib/nfs/etab 查看NFS服务端配置参数的细节。在NFS客户端可以通过
cat /proc/mounts 查看mount的挂载参数细节。
服务器端：
[root@nfs01 ~]# cat /var/lib/nfs/etab
/data 172.16.1.0/24(rw,sync,wdelay,hide,nocrossmnt,secure,root_squash,no_all_squash,no_subtree_check,secure_locks,acl,anonuid=65534,anongid=65534,sec=sys,rw,root_squash,no_all_squash)
客户端：
[root@web01 ~]# cat /proc/mounts
