Comment 31 for bug 824089

The messages about the barrier fail as such are just informational. The interesting part to me seems that while xvda and xvdc see the capacity change message, there is nothing for xvdb. Maybe I missed the info but it would be interesting to know what kind of mapping is used for the pv disk (probably all off them) in the xen guest configuration. And maybe there is something wrong with whatever the mapping target is?
