Folks, Has anyone got experience using s/w raid 5 and Xen? I''ve had a report of crash in xenblkd under high disk load, and would like to know whether this is a generic s/w raid5 thing, or something specific to the SATA controllers in this particular setup. Any relevant success or failure reports Thanks, Ian _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel
