Hi,

I am using AIX 4.0 on RS6000. Yestersday, I have increase the size of /tmp filesystem for dumping files.
Now, I want to restore the size of /tmp filesystem using smit, but the system does not allow to reduce the size of /tmp filesystem. I also try to delete the /tmp filesystem, also it is not allowed since it mounts to /dev/hd3.
What can I do now? remove logical volume hd3?

Could you put your /etc/fstab, /etc/vfstab or whatever the file is that defines how disks are mounted in AIX?
This problem could be related to mounting tmp in an area devoted to swap space. If that is the case you don't need to worry because in reality the size you see is the size of your virtual memory.

You can not decrease the size of a file system in AIX.
Start your system in maintance mode "single user",  unmount /tmp ,then remove the LV and the file system.
