From 4391e2334dfe9926917c86a8fd110f8dff0a5ca2 Mon Sep 17 00:00:00 2001 From: Greg Lehey Date: Sat, 7 Aug 1999 08:19:15 +0000 Subject: [PATCH] Import RAID-5 code. Add Cybernet copyright. OK'd-by: Chuck Jacobus vinum_ldi: Calculate the percentage used correctly. vinum_lsi: Flag detached subdisks. vinum_info: Request info: get the major and minor numbers and print them correctly. list_defective_objects: New function, for listing objects which aren't up after vinum_start.
