mount webdav fails on reboot

Question

i've got a vhost running ubuntu 12.10. i installed davfs2 and edited my /etc/fstab file like the following:

https://somedomain.de/webdav.php/somefolder/ /mnt/s02 davfs defaults 0 0

now mounting this using mount -a works fine. also if i type reboot after connecting using ssh on my vhost as root user, my drive gets mounted correctly.

but using the web-backend of my provider (digitalocean) and clicking "reboot" there, i get an error after my machine starts up:

any ideas why this is happening and how to fix this?

Solution

The error Could not resolve hostname 'hostname.de': host not found probably means the network is not up while trying to mount.

It is recommended to set the _netdev mount option that means: device requires network to be available. This way, it will wait until there is a link available before trying to mount:

https://somedomain.de/webdav.php/somefolder/ /mnt/s02 davfs defaults,_netdev 0 0

Saved my days. This is a rarely mentioned option for mounting davfs while it often needs a network connection to be available.
