Increasing space in file system

Hi Friends,

I want to cut space from one file system and add in another file system.
For example I have 100 gb space in /oracle/TST/oraarch
I wnat to cut 50 gb from this file system and add 50 in /oracle/TST/sapdata1.

Please hel, How I can do it.

Since we dont know your version and architecture, the answer will be general:
In order to be able to reduce file systems easily (online that is ..) you would have to have onlineJFS installed, and reducing a filesystem so you can increase size of another can be done only if both filesystems are in the same volume group.

Hi VBE,

HP-ux version is 11.31
Both file systems are in differenct volume group.
Onlie JFS is not there.

If you are usre its different VG ( and not lvol) then its bad luck...
You only possicility is if the volume group which contains /oracle/TST/oraarch has enough room (by reducing if needed the latter FS...) to accept a filesystem from the other ( holding /oracle/TST/sapdata1), in which case you create the new lvol and filesystem and copy/restore the content then remove the older (after umounting and testing throughly...) so you can use the freed space, its not a difficult task only it will ask for some downtime for the applications... It would be the same sort of job when you change disk systems ( I had a few storage migrations a few years ago...)
