Create test plan for SEL

Can you please update the Feature Interaction section to include FLR and Overstriping?</p> <p><a href="https://jira.whamcloud.com/secure/ViewProfile.jspa?name=pfarrell" class="user-hover" rel="pfarrell">pfarrell</a> has written the attached scripts, which demonstrate the functionality. He's provided a guide:</p> <blockquote><p>There are three test scripts and a test config attached. The config is “local.sh”.<br/> These demo scripts are written for a single node running the sanity config. (They assume the MDS/MGS are on the same node.)<br/> On CentOS7, setup would look like this:<br/> Replace:<br/> /usr/lib64/lustre/tests/cfg/local.sh with the local.sh attached here<br/> Run:<br/> /usr/lib64/lustre/tests/llmount.sh<br/> To set up the local file system.<br/> cd /mnt/lustre<br/> Then exec the test scripts, in any order. They print out what they’re doing and ask for the user to hit enter to continue.<br/> The main test_script.sh shows off the basic SEL extension functionality using pools. (This is a difference from the demo script.)<br/> The test_script_dom_pools.sh uses DOM &amp; pools to show off skipping a tier if it is already full.<br/> The test_script_plain.sh script shows off the normal file case – A simple SEL layout going to EOF. This layout can switch to new OSTs if the ones it’s using get low on space. This is a potential “default” layout for a whole file system, with or without tiering.</p></blockquote> <p>Thank you for the Self Extending Layout test plan. I have a few questions/comments on the attached, version 0.1, of the SEL test plan:<br/> PFL is “Progressive File Layout”, not “Partial File Layout” as stated in the Introduction.</p> <p>In the Introduction, the link for more information to SLE, <a href="https://connect.us.cray.com/confluence/display/LUSTRE/HLD%3A+Spillover+Space+-+Self-Extending+Layouts" class="external-link" target="_blank" rel="nofollow noopener">https://connect.us.cray.com/confluence/display/LUSTRE/HLD%3A+Spillover+Space+-+Self-Extending+Layouts</a> , does not work. Would you please put this information somewhere that we can access?</p> <p>Under Regression Tests, you specify that some Lustre test suites will be run with different SEL layouts set on the ROOT_DIR. Would you please include a link to those test results in the test plan or in this ticket?</p> <p>Similarly, would you please add the results of your small IO, large IO and MD performance testing to the test plan or to the ticket?</p> <p>Under Feature interaction/Snapshot, should a SEL test be added to sanity-lsnapshot.sh to cover the SLE/snapshot interaction?</p> <p>Is the functionality of the attached scripts from Patrick incorporated into some of the automated test scripts? If not, are there reasons why they aren’t incorporated?</p> <p>Note the 'demo' scripts attached have not been updated to use -z instead of -x.  So they need that update at least, and it would be good for Cray to re-run those and make sure they still work with current versions, as various things have changed.</p> <p><a href="https://jira.whamcloud.com/secure/ViewProfile.jspa?name=jamesanunez" class="user-hover" rel="jamesanunez">jamesanunez</a>, sorry about the internal link. The HLD is attached to the main ticket at <a href="https://jira.whamcloud.com/secure/attachment/30498/LUSTRE-98540817-120718-1412-90.pdf" class="external-link" rel="nofollow">https://jira.whamcloud.com/secure/attachment/30498/LUSTRE-98540817-120718-1412-90.pdf</a>.</p> <blockquote> <p>Thank you for the Self Extending Layout test plan.

If not, are there reasons why they aren’t incorporated?</p></blockquote> <p>no idea, I see them for the 1st time. if they are a kind of functional feature tests, this is already covered by new sanity tests.</p> <p>For reference -<br/> Old test plan: <span class="nobr"><a href="https://jira.whamcloud.com/secure/attachment/32695/32695_LUSTRE-SelfExtendingLayoutTestPlan-v0.1.pdf" title="LUSTRE-SelfExtendingLayoutTestPlan-v0.1.pdf attached to LU-12365">LUSTRE-SelfExtendingLayoutTestPlan-v0.1.pdf^{<img class="rendericon" src="https://jira.whamcloud.com/images/icons/link_attachment_7.gif" height="7" width="7" align="absmiddle" alt="" border="0"/>}</a></span> <br/> Updated test plan: <span class="nobr"><a href="https://jira.whamcloud.com/secure/attachment/33091/33091_LUSTRE-SelfExtendingLayoutTestPlan-090719-1129-72.pdf" title="LUSTRE-SelfExtendingLayoutTestPlan-090719-1129-72.pdf attached to LU-12365">LUSTRE-SelfExtendingLayoutTestPlan-090719-1129-72.pdf^{<img class="rendericon" src="https://jira.whamcloud.com/images/icons/link_attachment_7.gif" height="7" width="7" align="absmiddle" alt="" border="0"/>}</a></span> </p> Development Rank 1|i00hbj: Rank (Obsolete) 9223372036854775807
