Subject: [PATCH] mdadm 2.4: fix write mostly for add and re-add
Date: Fri, 31 Mar 2006 22:02:15 -0500	[thread overview]
Message-ID: <442DED37.9030504@steeleye.com> (raw)

[-- Attachment #1: Type: text/plain, Size: 182 bytes --]

The following patch makes it possible to tag a device as write-mostly on 
--add and --re-add with a non-persistent superblock array. Previously, 
this was not working.

Thanks,
Paul
