Within /etc/fstab the _netdev directive is being ignored so a mount to a remote server is failing during OS boot-up.

It's possible I may have uncovered a bug.

I'm having a problem getting a remote share to mount on boot.
The mount is attempted before the network interface is ready and I've got `_netdev` on the required line in `/etc/fstab` . . . .

 

//192.168.0.160/raspi /zeus/raspi cifs rw,auto,uid=1001,gid=1002,file_mode=0755,dir_mode=0755,_netdev,vers=3,credentials=/etc/.smbcredentials_raspi_01 0 0

 

Here is the part of `dmesg` that explains the issue better than I can:

At 863.282125 I manually issued the command `mount /zeus/raspi` which successfully created the remote fs mount.

I've been trying to sort this one out for more than a month.
Can anyone help me to get the OS to wait for the network physical link and IP protocol stack to be fully up before trying to connect to the remote share using the line in `/etc/fstab`?

try systemd automounter instead

Thank-you for the advice. This is a little bit over my head as I don't want to mess with the /etc/fstab and make the Armbian Linux unstable. I have noticed that the advice is for the Manjaro distribution of Linux that I've not heard of until this moment.

Here is the contents of my /etc/fstab file:

UUID=dffd2ee5-5480-480b-9853-7884f8ba5e47 / ext4 defaults,noatime,commit=600,errors=remount-ro 0 1
tmpfs /tmp tmpfs defaults,nosuid 0 0
//192.168.0.160/raspi /zeus/raspi cifs rw,auto,uid=1001,gid=1002,file_mode=0755,dir_mode=0755,_netdev,vers=3,credentials=/etc/.smbcredentials_raspi_01 0 0

 

The example shows how to mount a remote nfs file system.   I'm not sure how to apply this to my configuration.

I also had problems with cifs (on OSMC which is debian based like armbian). Using sshfs works well though:

share@ccb-adm035:/home/share /mnt/ccb_adm035  fuse.sshfs noauto,x-systemd.automount,_netdev,users,idmap=user,follow_symlinks,allow_other,reconnect 0 0

You need to have sshfs installed. Check you can ssh to the remote machine and ssh-copy-id to it so it doesn't need a password.

Thank-you @lanefu. Your pointer to a solution worked, but it took some time for me to learn how to do this.  Finally came across this one page that explained how to automount a share using systemd.

This worked for me:

root@loki:/etc/systemd/system# cat zeus-raspi.mount
