飞牛NAS的NFS共享报错：Permission denied-马春杰杰

之前用的是1.0系统，昨天升级了1.1.8，今天发现之前NFS共享的文件夹全都无法访问了，提示：Permission denied

这是exports内容：

# /etc/exports: the access control list for filesystems which may be exported
#                       to NFS clients.  See exports(5).
#
/fs/1000/nfs  *(rw,async,insecure,all_squash,no_subtree_check,insecure_locks,sec=sys,anonuid=1000,anongid=1001,fsid=1000)
/fs/1002/nfs  *(rw,async,insecure,all_squash,no_subtree_check,insecure_locks,sec=sys,anonuid=1002,anongid=1001,fsid=1002)

在其他服务器上也能看到：

我发现只有内部存储的文件夹可以正常访问，比如/vol1/NFSshare/mount/mashibo这个文件夹，其他的外部文件夹全都无法访问，升级系统之前是可以的。

主要是外部磁盘我需要xfs格式，飞牛自带的系统没有这个格式，所以只能挂载外部存储。

刚刚发现了解决方案：

先卸载/NFSshare这个磁盘，此时会自动变为默认的挂载点：/vol00/SEAGATE ST12000NM004J

然后再次卸载，之后，重新sudo mount -a（之前已经在fstab中写入规则了：UUID=84c13981-0780-4f7e-b7b2-6e3896675b9d /NFSshare xfs defaults,usrquota,grpquota,prjquota,nofail,x-systemd.device-timeout=10 0 0）

此时，不知道何种原因，/etc/exports下的自定义配置全部丢失，不过还好，重新填入NFS导出即可~
