hi all, in case someone else runs into it, it is the opfed-scripts rpm that has a postinstall and postuninstall script that changes the yum.conf (bad, mellanox, bad) for a pure/regular uninstall it works fine, but to swap ibutils from mlnxofed to ib stack from os, yum obviously doesn't know that the exclude will be removed. i've seen worse in vendor-provided rpms, but i guess it caught me offguard ;) stijn On 09/30/2017 11:51 AM, Stijn De Weirdt wrote: > hi johnny, > >>> anyone any hints how to debug this or some clues what could be going >>> wrong here. >> >> Do you have an exclude in /etc/yum.conf for ibutils-libs? > > how embarassing. there was indeed an exclude on ibutils-libs.
