How to fix inode errors on fedora 17 on my VPS

Hi,

Last night I was working on one of my VPS from (DigitalOcean) and suddenly the hard drive got into a read-only state.
I couldn't delete files even with root!?!

I rebooted and then the VPS went into a recovery mode. DigitalOcean Support was able to make it boot but  I am seeing errors in the log. Also I have tried backing up my files I created tar.gz and zip file but were corrupted.

Do you have any idea how to fix it the VPS? (I didn't have backups for that VPS)
