Hi, Is there something to visualize a crushmap ? It looks like balloon trees and hierarchical bundling (see fig 13a in http://www.aviz.fr/wiki/uploads/Teaching2014/bundles_infovis.pdf) would be a good match. It could show, for instance, where objects move when the crushmap changes. But I've never thought about it before and maybe someone already has an answer to the question ;-) Cheers -- Loïc Dachary, Artisan Logiciel Libre -- To unsubscribe from this list: send the line "unsubscribe ceph-devel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
