This is due to me running with a ko2iblnd DLC MultiRail configuration. The test suite assumes a tcp setup using modprobe.conf for ksocklnd only. Currently when running I see failures like:</p> <p>rmmod: ERROR: Module ko2iblnd is in use</p> <p>rmmod: ERROR: Module lnet is in use by: ko2iblnd</p> <p>rmmod: ERROR: Module ko2iblnd is in use</p> <p>rmmod: ERROR: Module libcfs is in use by: lnet ko2iblnd</p> <p>modules unloaded.</p> <p>Stopping clients: ninja82 /lustre/lustre (opts:-f)</p> <p>Also lustre_rmmod will completely fail with an o2iblnd LNet DLC multi-rail configuration.</p> <p>Simply attempting to execute lustre_rmmod with a system using lnetctl to set things up will show these problems.</p> Setting up any test suite to run test that use a post lustre 2.7 DLC configuration with ko2iblnd. LU-12126

The lustre test suite falls over when running with a modern LNet DLC configuration with o2iblnd
