a big file taking all space not trace-able and visible. how to delete?

[Rajeev Prasad]

Steve,
thats exactly how it happened. even after reboot i saw some ssh processes lingering. the ssh process were started by www-data using perls' Net::SSH lib - from my intranet web page. this box hoststhe LAMP server too. i do not know how perl's Net::SSH internaly manages ssh connections. but i am also confused how a process 'survived' a reboot?
 
anyway i am good now. only strange side-affect i have is that my gnome-terminal profiles got messed up. i had to re-create those.
 
thx again!

When you rm'd the file it was unlinked. The filesystem doesn't
actually get the space back until all processes which had a lock on
the file release that lock. That's why I suggested rebooting the
machine to ensure that all processes released their locks as I'd
assumed you'd already killed all processes which would have been
involved in this.

I'm confused though - if you already HAD rebooted the server, how did
you have to kill the SSH process after the reboot... obviously that
wasn't the order in which things happened!

Shouldn't be nercessary but it won't hurt.

When one person suffers from a delusion it is insanity. When many
people suffer from a delusion it is called religion.
