I have a quick question regarding the free disk space of a netbooted
machine. I'm new to this, but have an Xserve and am trying to see
how useful netboot might be.
I just turned an image created using netrestore into a netboot image
using the system image utility. It boots fine, but there is only
~300MB available on the disk. this quickly runs out as applications
are opened and causes issues.
Is there a step that I missed?
The one where you created an source disk and image the size you wanted?
However why is it that you need more space on your boot volume? This
is the bigger question since you don't want to be writing a lot (or
at all for best performance.)
What considerations are there with using netboot images for
everyday use (office apps, internet, etc) for temporary users who
don't need to store files locally, but DO need to be able to use a
range of applications which need to store temp files etc.
Realize that netboot is not meant to address the user side of the
equation, there are other tools/methods for that, netboot is meant to
solve the boot and diskless machine problem.
Realize next that having no local disk is general a performance
concern since w/o any local and fast I/O device you're dealing with
latencies that OSen that are built around message delivery trip over.
True diskless systems only make sense where you have total
application control with no need for heavy or rapid I/O turns, but
isntead for systems used in for things like kiosks, cafe terminals
and computational cluster members. (They're also idea for
troubleshooting, but that's a different application set entirely.)
So to answer:
What considerations are there with using netboot images for
everyday use (office apps, internet, etc) for temporary users who
don't need to store files locally, but DO need to be able to use a
range of applications which need to store temp files etc.
the answer is the consideration is *you don't* use diskless netboot
for these situations where users havge everyday workloads and need to
store lots of temporary files. These scenarios are better off with
local disk.
If you *must* netboot for the above applications you at least would
prefer a local shadow file.
