Continuing with my 8/31 2009 post, I erased the disks and reinstalled 9.04. Still had problem. Reading the mdadm wiki, kernel detection and assembly of arrays is considered deprecated, and only works with version 0.9 superblocks anyway. I use version 1.2 superblocks so that they are near the start of the disk so I can zero them out in a reasonable time when I want to reuse the disks. 8.10 did not have any problem assembling these. I don't know if it is because it FOUND them, or if it looked at mdadm.conf. I did not KNOW about mdadm.conf until a few days ago, so if it assembled them from mdadm.conf, mdadm must have created the file for me. Since arrays using version 1.2 superblocks *cannot* be auto-assembled, my mdadm.conf in 8.10 must have been created for me.
I did a "mdadm --examine --scan >> /etc/mdadm/mdadm.conf" and the system works fine. (Well, there are other mdadm segfault problems which I just put a bug report in for, but that is another story). So I conclude that *whatever* is supposed to create mdadm.conf when you create an array with command line mdadm commands worked in 8.10, and is broken in 9.04. -- mdadm software raid breaks on intrepid-jaunty upgrade https://bugs.launchpad.net/bugs/330298 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
