Reallocate disk space

[KenCunningham]

AIX 5.2 - I wish to remove a filesystem /dpp/train and reallocate the space to various other filesystems. All of these reside on the same datavg. Being mainly Solaris oriented isn't helping here and I was wondering whether anyone could guide me - I'm quite happy to post whatever information is required to allow me to achieve this. Thanks.

I want to be good, is that not enough?

lsvg datavg will show how much space is available in datavg
rmfs -r /dpp/train will remove the file system and the underlying LV
lsvg datavg will show newspace available
chfs -a size=newsize /otherfilesystem

newsize is in 512-byte blocks

man rmfs and man chfs should help
