The most likely mistake is that YOU are in a directory on the filesystem when you try to umount. In that situation you cannot umount even if you are root (unless you use the -f (force) switch which is not recommended).

umount.davfs
umount.davfs(8) 1.4.6 umount.davfs(8)
NAME
umount.davfs - Umount-helper to unmount a davfs2 file system
SYNOPSIS
umount.davfs [-h | --help] [-V | --version]
umount dir
SYNOPSIS (root only)
umount.davfs dir
DESCRIPTION
umount.davfs is a umount helper program. It is called by the umount(8) command. Its purpose is to prevent the umount command from returning
unless mount.davfs has synchronized all its cached files with the webdav server.
dir is the mountpoint where the WebDAV resource is mounted on. It may be an absolute or relative path.
While for local file systems umount(8) will only return when all cached data have been written to disk, this is not automatically true for
a mounted davfs2 file system. With this umount helper the user can rely on the familiar behaviour of umount(8). To inform the operating
system that the file system uses a network connection, you should always use the _netdev option, when mounting as davfs2 file system.
Depending on the amount of data and the quality of the connection, unmounting a davfs2 file system may take some seconds up to some hours.
If the mount.davfs daemon encountered serious errors, umount.davfs may return an error instead of unmounting the file system. In this case
try umount -i. The -i option will prevent umount(8) from calling umount.davfs.
OPTIONS
-V --version
Output version.
-h --help
Print a help message.
-f -l -n -r -v
This options are ignored. They are only recognized for compatibility with umount(8).
FILES
/var/run/mount.davfs
PID-files of running umount.davfs processes are looked up here.
BUGS
No known bugs.
