https://jira.whamcloud.com This file is an XML representation of an issue en-us 9.4.14 940014 05-12-2023 https://jira.whamcloud.com/browse/LU-12756 Lustre <p>lnet_select_pathway() contains a fair amount of duplicated code. I took a stab at refactoring this function and I believe I have a functionally equivalent implementation with about half as much code.</p> <p>During that process I noted that the lnet_nid2peerni_locked() function takes a ref on the lnet_peer_ni<br/> object that it returns, however most callers of this function do not need this reference as they hold a net lock when referencing the lnet_peer_ni. So some additonal code removal is possible here as well.</p> LU-12756

lnet_discover_peer_locked<br/> Project: fs/lustre-release<br/> Branch: master<br/> Current Patch Set: 1<br/> Commit: 148184da0238d4c533c4d3e9a6ecaebaa8efa635</p> <p>FYI, I plan the following test activities for this patch series.</p> <p>Port patch series to Cray's Lustre 2.12. All patches apply cleanly because our 2.12 LNet is basically identical to master.</p> <p>Deploy the code to dev system with Clusterstor server and small XC system (40 compute nodes, 4 LNet routers).</p> <p>Place load on system (IOR, mdtest, etc.).</p> <p>Perform LNet router failure testing over 24 hours. This involves: NMI a router, wait 15 minutes, reboot router, wait 15 minutes, repeat.</p> <p>Expectation is that there are no client evictions and no test failures.</p> <p>I will perform the above testing for the following configurations:<br/> 1. Test code on servers, routers and clients with default settings (Edit: Passed)<br/> 2. Test code on servers, routers and clients with discovery disabled on clients and routers (Edit: Passed)<br/> 3. Test code on servers, routers and clients with discovery disabled on servers. (Edit: Test fails due to <a href="https://jira.whamcloud.com/browse/LU-12955" class="external-link" rel="nofollow">https://jira.whamcloud.com/browse/LU-12955</a>)<br/> 4. Test code on servers, routers and clients with discovery disabled on clients servers and routers (Edit: Passed).<br/> 5. Test code on servers, clients and multi-rail routers with default settings.</p> <p>@Chris - my vote to add some performance testing against that series.<br/> As I see, it have touched a sort of hot code. So I think we need to add performance evaluation as similar as we have with MR routing testing.<br/> workload is same for all tests - mdtest + IOR with small record size (4k-8k).<br/> 1) new code on server <br/> 2) new code on routers also - <br/> 3) all nodes have same code.</p> <p>Oleg Drokin (green@whamcloud.com) merged in patch <a href="https://review.whamcloud.com/36534/"
