I am testing Ubuntu 14.04.2 LTS on Virtual Box. My ultimate goal is to build a real world RAID1 SAMBA home server. This is my first foray into a Linux distro. I have come a long way in the last 2 weeks though. I have a good understanding of root, users, groups, permissions, SAMBA shares, and mounts. Up until now, any trip ups I have had, I have been able to figure out with persistent "Googling" sites such as this one. This one has me stumped though.
Immediately after I installed
mdadm, I was no longer able to boot up. Message repeats:
Incrementally starting RAID array mdadm: CREATE user root not found mdadm: CREATE group disk not found Incrementally started RAID array
I can get the GRUB menu and have tried recovery mode...same message
I have tried Boot-Repair-Disk both using default repair and the
nodmraid option... same message after reboot.
I do not have RAID set up yet, I was hoping to do that with Webmin and
This is frustrating! How can I fix it to boot again and how can I successfully install
Update: I installed another Ubuntu along side the corrupted one and can now edit files in the original installation.
I have tried commenting out all entries of the
mdadm.conf file. I have also removed the
mdadm file and still cannot boot. Is there a way to remove the
mdamd package from the corrupted installation?
After not getting any answers to this question and spending endless hours trying to solve it, I went a head and re-installed. I knew all along that this was the easiest option, but I was really hoping to learn how to save a broken system. This time, I saved a snapshot right before installing
mdadm. No matter how I installed it (GUI, CLI, "no-recommondations") same thing, system would not reboot. A little more research indicated that Ubuntu doesn't play well with
mdadm. So I began looking for alternate distros. Currently I am playing with Xubuntu and liking it. And it breezed right through the
mdadm installation no problem.
All that said... I would still like an answer to... "How could I have repaired the original installation without a full re-install?"
