What good is this readme if "dmraid -s" doesn't come up with anything? I cannot recreate the problem any more, as the machine, as I wrote, has moved forward to an Escalade 8000 series controller (it's more convenient anyhow). Attached my original message from 4 weeks ago. -- Matthias Andree --sdtB3X0nJg68CQEu Content-Type: message/rfc822 Content-Disposition: inline Date: Tue, 8 Nov 2005 23:19:48 +0100 From: Matthias Andree To: Mauelshagen@RedHat.com Subject: dmraid vs. ICH7-R fakeraid Message-ID: <20051108221948.GA26912@merlin.emma.line.org> MIME-Version: 1.0 Content-Type: text/plain; charset=us-ascii Content-Disposition: inline X-PGP-Key: http://home.pages.de/~mandree/keys/GPGKEY.asc User-Agent: Mutt/1.5.11 Heinz, I'm not sure if you can read German or if that's adequate, so I'm writing in English. But if you find German more convenient, feel free to use it in your reply. I was recently asked to install SUSE Linux on a Primergy RX100S3, to find out that Linux's libata AHCI driver 1. doesn't support hotplug yet (as of 2.6.13, to be more precise), 2. doesn't understand the BIOS RAID stuff. It exposes my SATA RAID1 physical volumes as block devices though. I tried dmraid 1.0.0.rc8, but apparently it is unable to understand this Intel metadata layout. I then tried FreeBSD 6 since it claims support, and it (ataraid(4)) indeed detects the Intel software RAID layout properly; unfortunately the underlying ata(4) driver only detects the drive if the BIOS is set to "compatibility" mode which makes one drive disappear - so FreeBSD doesn't work for this particular machine yet (I presume 6.1 will do). However, as the FreeBSD kernel sources are open source and AFAIR without BSD advertising clause, it should be safe to ask: could you have a look at the FreeBSD ataraid(4) source code and see if you can learn the ICH7-R metadata layout and bring it into dmraid 1.0.0.rc10?
