Exactly same for me. I dont know if is it long delay -- I have never waited and switched comp off. I have several connections with Samba and NFS over OpenVPN. It seems OpenVPN stops BEFORE this and the unmoutn script is not able to unmout.
Very annoying. I created init script that will unmount all remote mounts before the openvpn stops - with no luck. Still it halts. -- Long delay unmounting remote filesystems on shutdown https://launchpad.net/bugs/49695 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
