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 umount= ed. '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 --------------enig5871917530EFF50C06433BF3 Content-Type: application/pgp-signature; name="signature.asc" Content-Description: OpenPGP digital signature Content-Disposition: attachment; filename="signature.asc" -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.18 (FreeBSD) iEYEARECAAYFAlEeZaQACgkQLDqVQ9VXb8gsHACdFEqlCR6P/TidOaRy5szVEzLI ZMgAnR19U1FX5jl7aBDZHXs6hXCKPGY3 =HXx2 -----END PGP SIGNATURE----- --------------enig5871917530EFF50C06433BF3--
