Hi,

I am having trouble increasing a LV or filesystem. I always got the
following error:

0516-787 extendlv: Maximum allocation for logical volume hd20
is 512.


Here are related information:

OS: AIX 5.3

# lsvg scrvg

0509 0509 hdisk1

Any help is appreciated.

So 1016 - 514 = 512 and you're probably trying to allocate
more than 512 * 64MBytes with your chfs command. Use:

chlv -x <new-max> <lvname>
