Hello everybody, I'll try to make this as simple as I can, but please be pacient with me, I never used Linux before and everything I know so far it's from Google's search and personal experience with the famous "trial and error".
Last week I was experiencing some issues with MySQL server and one of my dedicated server's hard disk partition. The main partition (where I have MySQL and Linux OS installed) was full, and I tried to free space moving some folders to another partition.
Because of my luck, and negligence, I move the folder "sbin" with another folders (can't remember the name of them) to the "home" partition. For my surprise, when I finished, I tried to access through SSH to my dedicated server (using PuTTY) and when I enter the root password, it says "wrong password". So I freaked out. I restarted the dedicated server, and I receive this error:
I immediately contacted the company that gives me the server but they told me the only thing they can do is restore the server and, of course, format (erase) everything on it.
I really freaked out x1000000, because I use it for work purposes and I didn't make a backup, because I started using it a few weeks ago.
Anyway, this people won't help me to solve my problems, but I started to think a few things about this:
1. Is there any way to format just ONE partition (the server has THREE), install Linux OS in that partition and then fix the issue in the partition where Linux OS corrupted is installed?
#### IN CASE IT IS POSSIBLE ####
How can I do this? Is like Windows like booting a CD and everything else? Can I do this with an external hard disk through USB?
2. Another ideas? Like solving this OS issue without formating and that stuff.
As I said, I'm using this server for work purposes and I have tons of clients' files in there, I can't afford such a loss like that, and I refuse to accept that it's the only "possible solution" to format an entire hard disk.
LAST ERROR I RECEIVE WHEN INITIATING SERVER:
## SOME INFO ABOUT THE DEDICATED SERVER
Intel Xeon - Linux CentOS 6
Don't know if it has optical drives like CD-RW.
Don-t know if it has USB ports, I think it should.
I have physical access for a limited amount of time, because it's in a private datacenter.
I really appreciate your time and help with this.
Thanks a lot.
Hope you can help me.
