Infrastructure Software

I have an NFS based Storage Repo which is hosting a VM and also has some ISO's uploaded to it.

There is something wrong with the repo now in that, I can't delete or upload ISO's to it, I can't create VM's on it etc..

When I try and delete an ISO I get:

com.oracle.ovm.mgr.api.exception.RuleException: OVMRU_002016E Cannot find a server to perform operation on repository: StorageRepo. A server must have a repository mount, be running, be owned, and have the appropriate storage connect plug-in

When I try and create a VM using this repo I get:

OVMAPI_9013E Cannot perform operation on Virtual Machine: test, no server available.

When I try and edit an existing VM on this repo I get "OVMAPI_6003E Object not found
Fri Sep 16 16:00:24 BST 2011" clicking through the wizard after the Storage options stage.

I have successfully created another Storage repo NFS exported from the same server and that is fine, I can create VM's on it etc.

Any ideas what's wrong and what I can do to fix this?

Thanks.
