Nevermind Bret, I fixed it after trawling the intarweb for a few more minutes.
I ran: sudo dppg-reconfigure mdadm Accepted all the defaults. If you've never played silly-buggers with your kernels, this *might* fix it for you, but as it was, I have built a couple of kernels before and the initramfs-update was trying to write to one of those (that I don't use). So I had to remove all the custom kernels and reinstall 2.6.22-14-generic in synaptic. I then ran dpkg- reconfigure again, it wrote the to correct kernel image, I rebooted, and my RAID works. Woo! Oh one important (I think) note, my mdadm.conf contains the UUID of my HDs, not names because the names seem to be quite fluid (they kept changing name every boot). If you're not set up like this, I suggest doing so. -- Software RAID sometimes fails to assemble arrays on boot https://bugs.launchpad.net/bugs/114170 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
