Re: Disk: Percent full a performance factor?

<snip>
On the flip side I have customers with IBM i 7.1 as a host partition
with nothing but NWSSTG filling the disk to 95%. They have been that way
for over a year and a half with no issue whatever because those things
are written to their full size when built and never move. The I/O is
just within them.

This sounds like our RACK#HST lpars.
They still have a lot of free space.
Many of the lpars they host are running somewhat high.

Only checked % Busy on 4 of these lpars other than the RACK#HST lpars I
reported on in an earlier email.
