From mboxrd@z Thu Jan 1 00:00:00 1970 From: Brad Campbell Subject: Information gathering script Date: Wed, 24 Mar 2010 23:10:13 +0800 Message-ID: <4BAA2B55.8040504@wasp.net.au> Mime-Version: 1.0 Content-Type: text/plain; charset=ISO-8859-1; format=flowed Content-Transfer-Encoding: 7bit Return-path: Sender: linux-raid-owner@vger.kernel.org To: RAID Linux List-Id: linux-raid.ids G'day all, Having just dropped a drive (it turns out 1TB SATA drives don't bounce) that belonged in my 10 drive RAID-6 and having replaced it this afternoon, I had a thought. When things go wrong (particularly those nasty things that cause the sick feeling in the pit of your stomach) the best help is always available give the right information. If there was a script that one could run when things were healthy that dumped all the relevant information for safe keeping, would it reduce the nightmare that is recovering a broken raid? I'd imagine an mdadm --examine on each component of a RAID, partition tables and perhaps a --detail on each md device. Is there anything else that might be handy that could be dumped to a verbose output just in case? Is there already such a thing?
