** Description changed:
Binary package hint: mdadm
In testing raid1 according to
http://testcases.qa.ubuntu.com/Install/ServerRAID1, the system installed
fine and both disks show up in /proc/mdstat. I installed using my
procedure found in
https://bugs.launchpad.net/ubuntu/+source/grub2/+bug/457687/comments/6.
I anwered 'yes' to booting in degraded mode. I noticed during install
the grub-install did reference both /dev/vda and /dev/vdb
However, if I remove the first disk (vda), the system drops to the
initramfs telling me the disk could not be found. If I remove the second
disk (after adding the first disk back), I'm told about the
'bootdegraded=true' option.
This ends up being a usability issue as well, because now 'Shift' is
needed to get to the hidden boot menu since this was the only operating
system installed.
I tried adding bootdegraded=true to the kernel command line when vda was
removed, and got the same message in initramfs.
+
+ =================
+ Karmic release note:
+
+ Automatic boot from a degraded RAID array not configured correctly after
+ installation or a mdadm package reconfiguration
+
+ Even if "boot from a degraded array" is set to yes during the install
+ the system will not be properly configured to automatically boot from a
+ degraded array. A workaround is to edit /etc/initramfs-
+ tools/conf.d/mdadm after installation to set BOOT_DEGRADED to yes
+ (BOOT_DEGRADED=yes) and then update the ramdisk with "sudo update-
+ initramfs -u" (462258).
