This is really disappointing. And it seems to contradict the umount.davfs description: "Its purpose is to prevent the umount command from returning unless mount.davfs has synchronized all its cached files with the webdav server. ... 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."

Then what should we do before turning off the PC and going home, to ensure all changes are uploaded and can bee seen from elsewhere? Is there a way to at least check the current upload status?

Could you please consider adding some "force sync" or "graceful unmount" facility, with some indication if it failed (e.g. no network)?

[field #14]      Original Submission: I have mounted a webdav directory with davfs2 via:
sudo mount -t davfs https://server/folder /home/mountpoint/

How can I force a sync via command line without unmounting the directory?
