Re: 12.04 lost my RAID
What do you mean "create the array"? When you have existing array you assemble it, not create it (it already exists). I hope you didn't try to use --create since you need to use --assemble.
What does:
cat /proc/mdstat
show? If you didn't assemble and mount the array during the install (and according to what you said you never said you did), it might be that mdadm.conf is not correct. What's its content?
For assembling existing array, you use:
sudo mdadm --assemble --scan
After it's assembled maybe you only need to write the config to mdadm.conf so that it's correct.
Darko.
