Novice user made a mistake on our Aux 4.3.3.3 risc 6000 F50. He wanted to increase space by a few hundred magebytes. Instead the number of pps was set to high from 42 to 52. No file system has been set to the new pps space yet. How can I reduce the pps to 47?. rebuilding the volumes is a really bad option, as it holds 120,000 low rez. images now.
