Disk i/o errors on FreePBX distro

So many problems restoring from backup.

In addition to certificates not work, every page gives UNDEFINED error banner, and I cannot activate the server.

It says:
This machine is not activated. Activating your system ensures that
your machine is eligible for support and that it has the ability to
install Commercial Modules.

If you already have a Deployment ID for this machine, simply run:

fwconsole sysadmin activate deploymentid |

So I do that, and it says:
Asking for deployment deploymentid…Error!
Unable to track down your deployment

So, i have gone back to using the failing old server with the constant disk i/o errors.
