I'm very new to Ubuntu and Linux in general, so please forgive my noobness.
I'm running an Ubuntu server, where the OS is installed on a SSD drive. In addition, I have 4 other drives in a software raid5. One of these drives failed.
I recently upgraded to 12.10, and after doing so, the system refuses to boot, and gets stuck after choosing what installation to boot.
I have replaced the failed drive with a new one, and now I'm trying to recover the system by booting from a USB installation drive, but I'm really stuck on what to do.
Some questions. 1. How can identify my SSD drive from the other drives, in case I will try a fresh install 2. How can I rescue my failed raid?
Any help is greatly appreciated, thank you!
