Unable to unmount /tmp

[columb]

We have a major problem with our file systems and we need to unmount /tmp, preferably without going into maintenance mode. We've stopped everything but whenever we run

fuser -c /tmp

it shows that the session we are using is using /tmp. There's nothing like logging in /.profile or /etc/profile which could cause this. Has anyone any ideas please?

Have you tried using lsof ?

You will probably have to install lsof if you want to use it. I don't believe it's part of the Base OS.

You cannot unmount /tmp in multiuser mode.

what have you got with this command : fuser -c /dev/hd3 (and not /tmp)

We've got to the point where I'm taking kHz's advice and going to maintenance mode. Thanks for all your input.

wise choice.

I'm not convinced this is correct - there is a lot of stuff in the AIX newgroup that implies you can provided the system is 'not busy' .

However I haven't actually tried it and would find it hard to justify not going into maint mode - after all it would have all been done by now !!
