I have a cluster of 6 machines. The other day we had a power cut and the fully functioning cluster turned off. Now we have turned it back on its no longer functioning and the person who was knew what he was doing has left. We are using openlava job scheduler on a linux machine (or set of machines) and it seems I have got this to work again. The problem is that the folder which was shared among our users is no longer visible for any of the computers but the host. Before the power cut I was able to log on and see my files by logging on to any of the computers. My question is how can I once again restore these settings? 

Thanks

So I have found some more information. It appears the folder is a NFS mounted folder. The computer that hosts the folder, lets call it 2, is not the machine that seems to be hosting the rest of the cluster, lets call this one 1. So I can get access to 1 and I can see the files I want to share on 1 but it doesn't look like I have access to 2 since its passworded. 

and I haven't found any 'ini' files, but I can access all of the machines (except 2) so I don't think the dns is down.
