Hello, Andrey.

Does geom_dev knows all needed bits of information to report? It seems to me, that it isn't. I mean: (1) Class and name of GEOM which is affected. (2) Name of provider which is affected. (3) Name of underlying provider which is lost (consumer from reporting GEOM's point of view). (4) Resulting state of affected provider (fixable, alive, dead). Yes, geom_dev knows name of FAILED provider, but does it knows all other? I'm affraid -- not, or I don't understand how generic mechanism could now, that geom_stripe could not lose components and still be fixable, and gome_mirror could. Additionally, some GEOM classes could throw away faulty consumers before they disappear from geom_dev point of view. Actually, DESTROY could be observed without my changes at all -- message from DEVFS about removing entry :) But, again, this notification will not contain name and class of GEOM, only provider's name (devfs entry). -- // Black Lion AKA Lev Serebryakov <lev_at_FreeBSD.org>Received on Wed Oct 05 2011 - 04:27:20 UTC
