Did it never occur that it's possible to _know_? Not unmounting is dangerous because there are in-memory buffers. Unmounting a filesystem syncs those buffers _to the physical medium_. What is anyone afraid might happen after that(*)? I'm a million miles from a kernel hacker but sheesh! It's not bloody rocket science! Understand your tools before you use them.

I suspect, umount (that always syncs) is enough and umount happens always at shutdown.

Re: "bioctl -d" before shutdown
Hi, I have the umount and bioctl -d commands in /etc/rc.shutdown, in case I forget to do it manually. If you don't do that proberly, you will need to fsck the device, next time you attach it. -Stefan Origineel bericht Van: Roderick Verzonden: zondag 24 februari 2019 21:53 Aan: misc@openbsd.org Onderwerp: "bioctl -d" before shutdown Excuseme that I ask instead of inspecting rc files. :) I do manually bioctl -c C -l /dev/XXX softraid0 and mount the resulting device.
