Hard disk failure

Hi there,

I have a Kimsufi dedicated server running Debian GNU/Linux and suddenly disk errors were found on root partition. Since I could not do any operation ("Structure needs cleaning" it said) I had to reboot it into rescue mode.
In there no hard disk was detected (neither on web interface :444 nor via SSH console with `lsblk`, `fdik -l`, `smartctl`) so I couldn't try to repair it with `fsck` or whatever.

The server can't boot because the damaged partition is the root one.
How can I proceed now? Can @OVHH maybe replace it?

Thanks.
