It looks like there was some damage to the filesystem. This could be related to the server going "down" hard or the physical disk going bad.
Have you tried waiting a little while and see if the journal recovery completes? If yes, then you will most likely need to chat with TAC and have them assist you. They can install a root patch and perhaps help you that way. Your set of commands are very limited from the CLI and you don't have root access.
If TAC is unable to help you then you will have to re-install. Hopefully you have a recent backup!
