    Exclamation HELP! Urgent! NFS to XENServer

    Help!

    We had to shutdown all our systems due to a power cut and A/C failure, now we're bringing everything back up and our XEN Servers won't connect to our Sun 7110 over NFS.

    The XEN Servers can ping the 7110, I can run "showmount -e 10.0.0.10" on the XEN Server and it can see the NFS share but I can't get it to connect.

    Please any help!!!!

    I've had the exact same issue with the 7110 and XenServer. Very quick question - are you running any DNS servers outside of XenServer (i.e. physical servers not VMs)? The issue I've found is centred around how solaris responds to NFS requests. It expects DNS to be alive so it can do a reverse DNS lookup. With DNS present (and the XenServer and 7110 both being present in DNS) it's fine - as soon as its not there you can't get it to connect. iSCSI doesn't have this issue.

    There are a couple of solutions to the problem. The first is if you have physical DNS server (or a physical DC with DNS) to ensure that the XenServer IPs and 7110 IP are both entered correctly and that DNS and reverse DNS lookups are working correctly. If you don't have a physical DNS server, then you can do what I did and bodge one together . Either running a windows DC on local XenServer storage, or run a separate linux bind server for the storage network. I did run a separate linux bind server on the storage network (was just a VM on local storage in XenServer) until recently when we put a physical DC back in.

    If you need any help let me know. Took me months to figure out this problem previously!
