Sorry for the delay. I sent this Sunday. Today I find out my posts to
LINUX-390 haven't been going thru because I haven't subscribed.
So I think my DROID has a different email address (outgoing), however I get all
my emails that I use to get.
So, now I'm off subscribing to all the listservs thru my Droid.
Anyway, following is a repost of my comment:

What I gathered from the original post was not being able to apply maintenance
due to being out of disk space. Well if the failure is caused by memory/swap
filling up, increase virtual memory instead of adding a real 3390 to swap for
temporary problems.
I run many small, very small Linux guests that I do have to increase virtual
storage when I apply maintenance. The smallest zLinux machine I ever got real
work out of was a 24 MB machine using IUCV for IP connectivity to VM's TCPIP
machine. It was just a router. Currently, my smallest machines are 48 MB (ftp
servers), and you just can't apply maintenance anymore (yast with connection to
a vswitch) in a 48 MB machine <G>. Memory is cheap, until you have to buy it.

Just curious as to what this has to do with adding disk space?
