Hello Stackers, I am using dell emc iscsi driver on my centos 7 queens openstack. It works and instances work as well but on compute nodes I got a lot a faulty device reported by multipath il comand.

I do know why this happens, probably attacching and detaching volumes and live migrating instances do not close something well.

I read this can cause serious performances problems on compute nodes.

Please, any workaround and/or patch is suggested ?

Regards

Ignazio
