You aren't very specific. Yes . Thank you . I think , I had this bug , when i see this in my /var/log/messages .

This bug occur in every raid10f2 or it's occur when physicals devices have not the right size ( aka after all operations there are no rounding needs ) or when the number of physicals devices > 2 ? Generally i build my raid device in degraded mode , i move data with pvmove , and after i push the remaining disk and i do a resync . -- ____________________________________________________________ / Erwan MAS /\ | mailto:erwan@xxxxxxxxxx |_/ ___|________________________________________________________ | \___________________________________________________________\__/ -- To unsubscribe from this list: send the line "unsubscribe linux-raid" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
