How can I increase the efficiency of /usr ? It shows a measly 33% efficiency in smit, when everything else is near 100%. Any help would be appreciated. We would like to have room for emacs and mathematica in /usr/local on our RS/6000 with 320 MB ! -- = Ulf (Olaf) Wostner = Math Dept, CCSF "Never met a deadline I didn't like." = wostner@garnet.berkeley.edu; voice 415-848-2343; fax 415-649-7830

This does not indicate the efficiency with which the filesystem space is being used, as you appear to believe. It is a measure of how the physical blocks are allocated in the filesystem, with a contiguous run being 100%. 'lslv -m hd2' will show the block layout, yours will have several small contiguous blocks, perhaps as a result of irregular software installations, which will increase /usr automagically as needed. One way to increase efficiency (does it really matter?) is to: 1- Do an initial install of everything 2- Note how much space is taken by each filesystem 3- Install again, but pre-allocate space before installing lpp's, allowing around 90% occupancy. 4- Wonder if the extra effort was worth it *&^) 5- Realise that you have no idea how much will be installed in the future 6- Wonder if the extra effort was worth it I went through this exercise (it's hard to shake a VM mentality) and still ended up with a 75% efficiency for /usr -- Graeme Moffat g.moffat@aukuni.ac.nz \ Time wastes us all, Computer Aided Design Centre, Fax: +64-9-366-0702 / our bodies & our wits School of Engineering, Ph: +64-9-737-999 x8384 / But we waste time, University of Auckland, Private Bag, Auckland, NZ \ so time & we are quits

But, you're right, it was a measure of the distance between physical paritions on a disk for a logical volume, and I don't think it really has any bearing on performance. >-- >Graeme Moffat g.moffat@aukuni.ac.nz \ Time wastes us all, -- *=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*= Julie A.
