Bug ID: 200784
Summary: Slow shutdown on r283297 amd64
Product: Base System
Version: 11.0-CURRENT
Hardware: amd64
OS: Any
Status: New
Severity: Affects Only Me
Priority: ---
Component: kern

FreeBSD 11-CURRENT shutdown.patch
The slow shutdown is caused by some remote smbfs shares mounted via openvpn:
the remote drives are unmounted after the openvpn daemon termination, this
induces some long timeouts. The solution is to unmount the smbfs shares in a
shutdown script before the openvpn daemon termination. I have discovered this
issue with this ‘dirty’ patch that displays the unmounted fs at shutdown.
For testing the the patch apply it in /sys/kern, rebuild and install the
kernel.
Set the new OID:
# sysctl kern.shutdown.show_umountfs=1
Halt the system:
# shutdown -h now
