Hi Folks, I recently used the chfs command to expand the filesystems on my disk. Unfortunately I made /usr unnecessarily large. Now chfs will not allow me to reduce the size of /usr. Does anyone know how to do this (other than reformatting the disk ;-) ? Thanks Freddy ------------- Freddy Jensen Display Postscript Group Adobe Systems Incorporated 1585 Charleston Road, P.O.

Our rep says that will come with aix3.2. -- Jeff W. Boote SCD/NCAR boote@ncar.ucar.edu Boulder, Colo

To do what you want, try the following: 0. figure out how large you really want /usr to be remembering that it's very easy to increase it later 1. backup /usr 2. remove /usr -> you have to do this in maintainence mode 3. remake /usr with a smaller size 4. restore /usr You can do most of these steps in smit. Good luck. -- Luis Basto Work: (512) 823-3081 Usenet: ...!cs.utexas.edu!mavrick!luis

Does anyone know how to do this > (other than reformatting the disk ;-) ? - telinit 1 - umount all - archive /usr onto tape - delete the /usr logical volume, using smit or rmlv/rmfs/whatever - create a new /usr logical volume of the correct size - restore /usr from tape - mount all - telinit 2 A bit tedious, but it does save all the installation/update/patching/ configuring you've done in /usr. -- Chuck Karish karish@mindcraft.com

From the feedback I've gotten here on my similar posting, we're SOL. We just spent two days backing up and restoring. Took us a few trys to get it right :-( -- ##################################################################### # CompuServe: >INTERNET:uunet.UU.NET!ki!dwatts Dan Watts # # UUCP : ...!{uunet | wgc386}!ki!dwatts Ki Research, Inc. # ############### New Dimensions In Network Connectivity ##############
