I mounted a remote file system via shfs. Suddenly I could not access the remote files any more. So I tried to umount the filesystem, but it responded "device busy". So I tried to lsit the processes which access the filesystem via "lsof >mount point<". The result was:
lsof: WARNING: can't stat() ext3 file system /dev/.static/dev
Output information may be incomplete.
after which the console widow froze (even CTRL-C did not work any more).
Using ps (as root) prints some processes, then freezese as well.
What did I do wrong?
What to do now?
