防止 CIFS 挂载不断查询 SMB 共享 Keep-Alive

Question

我有一个 fstab 挂载点定义如下：

//host.local /media/share1 cifs noexec,nofail,auto,nouser,_netdev,credentials=/home/foo/.smbcredentials,gid=1000,uid=1000,rw 0 0

网络共享在本地 NAS 服务器 (QNAP) 上可用，配置为在不活动后 15 分钟内暂停磁盘存储。当使用 nautilus 浏览 samba 共享时，这是按预期工作的。然而，当使用 cifs 挂载时，客户端会定期使用看似空的请求“Command: Create (5)”或 Keep-Alive“Command: KeepAlive (13)”查询 NAS。 NAS 以“STATUS_SUCCESS -> Create Action: The file Been and wasopened (1)”或 Keep-Alive 响应进行响应。

我能否以某种方式使 cifs 不定期 ping NAS 共享，以便 NAS 最终可以进入待机状态？否则，NAS 会持续处于活动状态、发出噪音，并且可能会过热。
