Re: Debian install using LVM

[Ray Mansell]

Martha...

I've been fighting the same thing all afternoon. Thought I was going
bonkers, since it all worked so well last week. For the moment I've
installed without LVM, but there's certainly a problem.

The timestamp on the install files I'm using is April 2, so they are pretty
new.  The level of Debian is jessie.

Has anyone run into this?

By "that step" do you mean something the installer is doing that you can't tell 
exactly what is happening?  Or is it a command you're running yourself?

While I don't personally care for this kind of setup, it should be fairly 
straightforward.  /boot needs to be mounted at the time zipl is run.  It needs 
to have a file system of ext*, xfs, reiserfs, etc. on it, not something like 
btrfs.

What do the contents of /etc/zipl.conf look like?  What are the messages you're 
getting back that indicate failure?

I recommend to try testing aka stretch. There were LVM fixes uploaded
there. As usual do attach /var/log/syslog from the d-i to help
debugging what's going wrong.

Note there is also Debian specific mailing debian-s390:
https://lists.debian.org/debian-s390/

Dimitri.

Debian install using LVM

[Martha McConaghy]

I've been fighting with a Debian install all day and wonder if anyone else
has run into the same problem. I wanted to use LVM for the root filesystem,
so created a /boot partition and an LVM for the rest.  Everything works fine
until it comes to the step where it tries to write out ZIPL.  That step fails.
I tried all sorts of combinations, but the only that actually works is
creating 1 partition for / with no LVM at all.  Something is not right.

Additional session - Hillgang

[Neale Ferguson]

Here is the abstract for the Crypto session for Wednesday’s Hillgang
meeting:

"This session will cover the functionality that cryptography provides.
Cryptography is much more than hiding or scrambling data.  In addition to
securing (hiding) data, crypto also provides integrity and authentication.
 We’ll look at some of the algorithms that provide crypto functionality
and why you need all of that functionality.”

This is in addition to Mike Riggs’ session on Linux/VM/VSE at VA Supreme
Court (aka what happens to that speeding ticket I got); CA on VM:Secure;
and Intro to and demonstration of Docker on z.
