Do you actually use the name /dev/md_d0 in /etc/mdadm/mdadm.conf? Maybe you updated the superblocks to that name but not mdadm.conf.
The following will recreate a static mdadm.conf and update the initramfs images: # start your array manually # cp /etc/mdadm/mdadm.conf /etc/mdadm/mdadm.conf.bak # /usr/share/mdadm/mkconf force-generate /etc/mdadm/mdadm.conf # update-initramfs -k all -u ** Changed in: mdadm (Ubuntu) Status: New => Incomplete -- mdadm assembling -but not auto assembling- after crash https://bugs.launchpad.net/bugs/381183 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
