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-9121 Lustre <p>It is sometimes desirable to fine tune the selection of local/remote NIs used for communication. For example currently if there are two networks an o2ib and a tcp network, both will be used. Especially if the traffic volume is low the credits criteria will be equivalent between the nodes, and both networks will be used in round robin. However, the user might want to use one network for all traffic and keep the other network free unless the other network goes down.</p> <p>User Defined Selection Policies (UDSP) will allow this type of control. </p> <p>UDSPs are configured from lnetctl via either command line or YAML config files and then passed to the kernel. Policies are applied to all local networks and remote peers then stored in the kernel. Whenever new peers/peer_nis/local networks/local nis are added they are matched against the rules.</p> LU-9121

Multi-Rail: User Defined Selection Policy

New Feature Minor Resolved Fixed Amir Shehata Amir Shehata Tue, 14 Feb 2017 17:20:38 +0000 Sat, 14 Oct 2023 10:50:44 +0000 Fri, 26 Feb 2021 14:39:02 +0000 Lustre 2.15.0 0 17 <p>This feature looks very nice.</p> <p>We are interesting in using something very similar to select LNET routers based on peer NIDs.</p> <p>It could be nice if we can prioritize how LNET routers are picked when sending messages to remote peers using this kind of feature.</p> <p>It would also be desirable to assign interfaces to targets. For example if there is MDT and OST running on a single host one may want to assign one interface to the MDT and one to the OST.

255 chosen as the "lowest" priority? I think that will result in misconfigurations. Am I the only one that thinks that?</p> <p>This is consistent with how priority is defined in other parts of LNet. For example routing. priority 0 is highest. So it seems like it's a good idea to remain consistent.</p> <p>Amir Shehata (ashehata@whamcloud.com) merged in patch <a href="https://review.whamcloud.com/34253/" class="external-link" target="_blank"
