A Windowsserver provides a network directory called data via CIFS/SMB protocol. The data folder is mounted on a Linux client with password and user authentification.

Sometimes the drive gets disconnected, but is available again after a second. I do not know exactly why, but it seems to be because of the Windows server or a broken network component.

How can I make Linux reconnect automatic as soon as possible?

    Try mount it with the _netdev option, it might help if you having network problem on the Linux client.

    @Intenso Can you provide a source for this? The man page said: _netdev The filesystem resides on a device that requires network access (used to prevent the system from attempting to mount these filesystems until the network has been enabled on the system). Jun 12, 2013 at 18:16

I'd recommend mounting it via autofs. This is a service that will mount a directory on demand (for example if you cd into it or ls it) and unmount it automatically after a user defined timeout.

  • Install the autofs package for your distribution (by the way, remember to include your distro in your questions since an answer's details may depend on it).

  • Add the following to /etc/auto.master

    /media/[my_server] /etc/auto.[my_server]

    Where /media/[my_server] is the mount point of the share.

  • Create a file /etc/autofs/auto.[my_server] with this line:

    [any_name] -fstype=cifs,[other_options] ://[remote_server]/[share_name]

For more information see here and here.

    What is [any_name] - is it literally the string [any_name], or is it just some arbitrary piece of text?

  • Oh, right, [my_server] is the parent of the mount point, and [any_name] is the actual mount point (eg. the share name).

    Could you provide a real example of what [my_server] and [any_name] would be? Aug 18, 2018 at 19:25

To add to the autofs answer, I recommend doing the the way it is described here:


That is:

  • Make the first field in auto.master is always /-.
  • Use full mount name in /etc/autofs/auto.server.

So in my case, /etc/autofs/auto.master contains:

/-      /etc/autofs/auto.nas

And /etc/autofs/auto.nas contains:

/home/rkitover/nas -fstype=cifs,credentials=/home/rkitover/.nascredentials,uid=1000,gid=1000,iocharset=utf8 ://nas/rkitover

This works for me!


Just to offer another angle, a current solution is doing this with systemd, as described here:
