Well, there are not backups of that valuable lost data but the cluster
was using disk mirroring but no one has a clue of how to take advantage
of that. Nobody here is a cluster expert and that has been the problem I
guess.
We haven't really "touch" any important system file, after physically
installed the hard disk, we realized that the cluster wasn't properly
working. We rebooted the cluster without the old disks and that has been
the result.
Worst scenario, we will need to call an expert, but we think it can not
be a big deal as I said, we haven't modified the previous configuration...

We were trying to install new hard drives to the system but something
that we don't know went wrong and it ended up in almost 4 years of work
lost!!!
Please, let me know what else can I do to be able to get the data back!

It's a bit late now, but I suppose you don't have backups?
As for how to help, what you provided was only marginally helpful. We
need a much more extensive overview of your setup and configuration,
versions, etc. before we can have any idea if we can help.
In the short term, don't try anything yourself without careful thought.
If the data is very valuable, consider hiring a data recovery firm near
you who can come and look at your setup.
