===== Summary =====

We have 6 vossi machines.  They are intended to be used as developer playgrounds since they have system resources far greater than the usual Developer laptop.

===== Installed OSes =====

===== Use Suggestions (for devs) =====

Here are some suggestions to maximize the use of the system resources these machines provide.

==== Scare off other devs :) ====
Create an MOTD that displays whenever anyone logs in:

''vim /etc/motd''

<code>
*******************************************************************************

                                STOP!

           This machine was promised to Joe Dev for exclusive use.

Check https://wiki.sepia.ceph.com/doku.php?id=hardware:vossi&#installed_oses to
          see if there are any others available for exclusive use.

      Let dmick or akraitman know if you need a different OS installed.


                               Thanks!

==== Building Ceph on an SSD ====
If you want to build Ceph on an SSD (the main OS and ''/home'' are on a spinner), find an SSD that's not in use (''sd{b..e}''), then:

<code>
mkdir -p ~/src
sudo mkfs.xfs /dev/sde
sudo mount /dev/sde ~/src
</code>

Then clone ceph.git to ''~/src'' and do your thing.
