I'm assuming most zSeries system use a standard 3390-3 volume (or less) for their base systems. What I've noticed in the last few releases for zSeries and in RHEL3 (beta) especially is the burgeoning size of /usr.
For SuSE SLES8, I could get by with moving /usr to a separate volume and I could everything but the document pdf's on the volume. I tried to install EVERYTHING on the redhat beta and I had /usr on its own 3390-3 volume and the install wizard said I needed another 1179 MB! (Being a development shop, some of our people actually use a lot of this stuff). In fact, after a pared down install, I only used 6% of the / volume and 72% of the /usr volume! What alternatives do we have in the zSeries world for this ever expanding filesystem? - Larger volumes on an RVA or Shark (which performance less well with lots of data behind a single UCB - no PAV's)? Do a lot of people use large volumes on shark or RVA? Do a lot of people actually use the SCSI feature of shark? - After building a minimal system, move /usr to an LVM volume? - Other alternatives? I understand that the POSIX specs insist on certain things, but what you end up with is about 15 direcotries using 8% of your space and one directory using 92%. And the software install wizards of the major distributors follow the POSIX rules... ===== Jim Sibley Implementor of Linux on zSeries in the beautiful Silicon Valley "Computer are useless.They can only give answers."
