During startup i get the following output of netmount: * Mounting network filesystems ... mount error(16): Device or resource busy Refer to the mount.cifs(8) manual page (e.g. man mount.cifs) mount error(16): Device or resource busy Refer to the mount.cifs(8) manual page (e.g. man mount.cifs) mount error(16): Device or resource busy Refer to the mount.cifs(8) manual page (e.g. man mount.cifs) * Could not mount all network filesystems [ !! ] * ERROR: netmount failed to start ... and the netmount service is not started. However, each netmount i have specified in /etc/fstab is mounted correctly. The failed netmount then is not stopping on shutdown, which causes the failing umounts of underlying local filesystems. mount: ------- //dfs/till/data on /home/till/data type cifs

For cifs file systems, you should not specify _netdev in the mount options; cifs is always a network file system. Try removing cifs from the mount options for the network file systems in fstab and report back whether or not this works. Thanks, William
Removing "_netdev" did the trick. THX However, its somewhat unintuitive. I thought that every network share should have the _netdev option, such that netmount knows about which filesystems to mount. Is there any place that explains the _netdev option in more detail? Why does adding this option harm netmount?
I was initially confused about the use of the _netdev option as well; however, documenting this is not an issue specifically related to OpenRC. Netmount first mounts all file systems that we know are network file systems. We know this by the type of the file system, cifs or nfs are a couple of examples. Then, netmount mounts all file systems with _netdev in their mount options. The _netdev option is used to delay the mounting of *any* file system until after the network is active. If you use it with a file system that we already know requires a network connection, netmount will mount that file system twice and you will get this failure. The example I am aware of that uses _netdev is iscsi, but I'm sure there are others. The _netdev option is mentioned briefly on the mount man page, but I'm not sure how well it explains this usage.
