Author: mav Date: Thu Dec 24 13:38:02 2009 New Revision: 200940 URL: http://svn.freebsd.org/changeset/base/200940 Log: As soon as geom_raid3 reports it's own stripe as sector size, report largest underlying provider's stripe, multiplied by number of data disks in array, due to transformation done, as array stripe.
