Mark, Where do you define this I use this command to define a diskpool: def devclass fileclass devtype=file maxcap=64g dir=/testfs def stgpool filepool fileclass pooltype=primary maxscratch=100
/testfs is a JFS2 filesystem. How big can /testfs grow to? The documents say 1TB. When volumes are created in the stgpool filepool, it creates a volume of 64G, which is the max value you can specify. Where do you define the 500GB you said.
