5.1-BETA umount problems

[Andre Guibert de Bruet]

Hi,

Have a look at the following:

bling# umount -f /lib
bling# umount -f /var
bling# umount -f /tmp
bling# df
Filesystem  1K-blocks      Used     Avail Capacity  Mounted on
/dev/ad4s1a    253678    114254    119130    49%    /

/lib/oldbackup has about 130GB worth of dumps in it, none of which are
displayed in ls. /dev/ad2 becomes unmountable because it's busy and
/lib/oldbackup contains nothing because it's unmounted. Is there a trick
to get out of this catch-22? All filesystems in bling are UFS2.
