The RAID is a data volume only containing /home, everything else is on a single small SSD. The boot bug I would not see as a result.
The mdadm signatures are on partitions only, not whole disks. The dmraid signatures on on the whole disk MBR's according to the BIOS. I have not removed them and don't intend to because the disks work fine with dmraid removed and mdadm reading the partitions. Not going to experiment on these disks now that they are loaded and backed up. I would worry about corrupting the partition tables and losing 5 hours of copying time. Both signatures at one, both in MBR and NOT on partitions, I assume would cause the last one written to corrupt the first one written. Current setup is mdadm raid, and it works. -----END PGP PUBLIC KEY BLOCK----- > Date: Tue, 20 Mar 2012 18:38:49 +0000 > From: [email protected] > To: [email protected] > Subject: [Bug 958334] Re: dmraid_1.0.0.rc16-4.1ubuntu7 blocks reading some > disks, resets others > > There is currently a bug in precise that prevents booting from dmraid. > If you want to switch to madm, you can still have dmraid installed, but > you need to clear the dmraid metadata from the drive in order to use it > with mdadm instead.
