The scope of Lustre support matrix has grown due to the community involvement but the testing has been very limited and the results often go unpublished. Whamcloud is resourced restrained to support every platform requested. Discusses have opened up about how
to create testing sites outside of Whamcloud that are tied into the general testing frame work. This is with the goal of enabling external sites to running the equivalent tests Whamcloud's does when work is presented to OpenSFS Lustre source tree and have
the results published the the general Maloo testing framework. This talk will go over what needs to be done to create such a setup.<br>

<div>Hello!

</div>
<div> the sizing really depends on your test scaling requirements.</div>
<div> For example my own test infrastructure is a couple builders + 4 nodes for VMs (each has 256G RAM), 160 VM pairs in total,</div>
<div> and on a particularly busy day another 80 VM pairs can be added. This is to ensure speedy feedback to developers.</div>
<div> You can operate a much smaller scale testing system if you want, just keep in mind what is the longest running test would take</div>
<div> to understand how many patches could be tested in parallel (sometimes patch bombs result in 20+ patches submission at the same time).</div>
<div> Here’s stats for last 30 days. <span style="color:unset; font-family:unset; font-size:unset; font-variant-caps:unset; letter-spacing:unset; text-align:unset; text-indent:unset; text-transform:unset; white-space:pre-wrap; word-spacing:unset; text-decoration:unset"><a>hxxps://imgur.com/lk2ogJv</a>
1 item means single patch n processing. time in testing for a patch is typically about 3.5 hours.</span></div>

Currently there are:</div>

<div>- the Janitor (also started with above codebase but got changed and extended a lot)</div>
