LNET fails to start with aliased interface in configuration

Improvement Minor Resolved Fixed Liang Zhen Cliff White Tue, 26 Jul 2011 13:04:08 +0000 Thu, 25 Apr 2013 18:14:56 +0000 Wed, 14 Dec 2011 15:42:47 +0000 Lustre 2.0.0 Lustre 2.2.0 0 6 <p>it's because kiblnd_create_dev() doesn't allow to dev_get_by_name() to return NULL (we add this for supporting failover of ib-bonding), but this can happen for aliased interface, we can fix this by simply remove the limitation and set kib_dev_t::ibd_can_failover to 0 for aliased interface.</p> <p>patch is here<br/> <a href="http://review.whamcloud.com/#change,1148" class="external-link" target="_blank" rel="nofollow noopener">http://review.whamcloud.com/#change,1148</a></p> <p>Cliff, I wonder why you'd need to use "o2ib0(ib0:0)" in the first place. Can you please elaborate a bit?</p> <p>Isaac, one reason I want to have this patch is because we didn't use to have this limitation before we adding ib-bonding failover, so if some users had a modprobe.conf which used aliased interface, they can't use it anymore, although I don't know any strong reason of keeping use it, <img class="emoticon" src="https://jira.whamcloud.com/images/icons/emoticons/smile.png" height="16" width="16" align="absmiddle" alt="" border="0"/>.</p> <p>Thanks for review!<br/> Liang</p> <p>Actually there is one good reason why o2iblnd must support aliased interfaces. See:<br/> <a href="http://lists.lustre.org/pipermail/lustre-discuss/2009-June/010922.html" class="external-link" target="_blank" rel="nofollow noopener">http://lists.lustre.org/pipermail/lustre-discuss/2009-June/010922.html</a><br/> <a href="https://bugzilla.lustre.org/show_bug.cgi?id=18602" class="external-link" target="_blank" rel="nofollow noopener">https://bugzilla.lustre.org/show_bug.cgi?id=18602</a></p> <p>One of the issue I have seen is for a config that have bonding of two 10G tcp between a lnet router and servers. We never be able to use both links in write since the tcp session choose only 1 at a time. The solution could be is to split the osts to two different interfaces on top of the bonding. We never tried this but could use alias on top of the bond to achieve this.</p> <p>Not sure if it makes sense <img class="emoticon" src="https://jira.whamcloud.com/images/icons/emoticons/smile.png"
