My coworker has a desktop computer with
/home shared on our file server. I have developed a Perl script for
sshfs-mounting a certain directory on another SSH host which works fine on my laptop.
On his computer the script fails to dismount the
sshfs at the end and leaves the mountpoint unclean. I didn't find any way to recover the mountpoint other than rebooting. After some testing I found that the difference between our setups is that his
/home is on NFS. In his
/tmp it works flawlessly.
After mount, during script operation everything is fine. But when killing the
sshfs process it is listed as
ps until the parent process (the Perl script) exits. When running a raw
sshfs command on the shell the problem still occurs.
ls -dl output for the mountpoint looks like this (as remembered - I have no real copy of the shell output at hand):

The sshfs mount is still listed by

I searched Google but only found lots of comparisons between sshfs and NFS for running network filesystems. How can I do a sshfs mount/unmount in NFS directory safely?
