Hello,
while playing with new jail features, I recognized that manually
umounting doesn't work as I'd expect.
After jail has been destroyed, the following mountpoint is active:
/dev/gpt/jailname1ROOT on /.jail.jailname1 (ufs, local, read-only)
There was var mounted to /.jail.jailname1/var but that sucessfully umounted.
'fstat' also shows no open files in /.jail.jailname1
But when I do 'umount /.jail.jailname' I get "Device busy" returned.
Some minutes later umounting works.
But I always have to wait some time, although nothing is open and
nothing is mounted above.
Does anybody have an idea what could cause that false "Device busy"?
-Harry
