Bug 4666

Summary:	umount -f doesn't seem to work
Product:	Base System	Reporter:	David Muir Sharnoff <muir>

Status:	Closed FIXED
Severity:	Affects Only Me

Description David Muir Sharnoff 1997-10-01 08:10:01 UTC

	 # umount -f -h tmp
	 nfs server tmp:/: not responding
	 # umount -f /net/tmp
	 nfs server tmp:/: not responding
	 # umount -f /net/tmp/usr
	 nfs server tmp:/: not responding
	 # df
	 nfs server tmp:/: not responding

	 I should mention that the machine formerly known as 'tmp' is
	 currently in the mail.

How-To-Repeat: 
	Mount a filesystem as above.  Turn of the NFS server and mail
	it somewhere.  Try to unmount the disks without cheating.

This is what one would expect how umount -f is working, but not what
is described for umount -f: forcibly unmounting is currently only
defined as ``don't care about resources that are locally still in use,
but revoke them''.

Anyway, i think this is already in Doug Rabson's queue of ``nice to
have'' things.  If i'm not totally mistaken, there might already be
another open PR for it.  Did you check before filing?

Never trust an operating system you don't have sources for. ;-)

No.  It seemed like a bug to me.
