(Ubuntu 10.10 + mdadm 3.1.4) I have my raid described in /etc/mdadm/mdadm.conf:
HOMEHOST <system> ARRAY metadata=imsm UUID=46e68921:eea24d1d:e933eee8:192d55bc ARRAY /dev/md/Volume0 container=46e68921:eea24d1d:e933eee8:192d55bc member=0 UUID=b39c8d9d:ab2fcd08:f4559292:981754f1
I have also done the following:
update-initramfs –k all –u
BUT my RAID does not automatically assemble upon boot. I actually have to run the following on command line:
sudo mdadm -As
in order for the RAID to initialize. I read that you are supposed to run that update-initramfs command if you change your mdadm.conf, but it appears that it didn't really do anything. What am I missing?
