Problems when run File Server under a cluster

Hello, I have configured my File Server (not AOS server) under a cluster and all run correctly. The problem arrives when the node cluster fail. The cluster service restart correctly and the shared disk where the file server is installed work propertly, but all clients connected on any instances from aos which uses this file server fall in error.

The error is related to files axsys.aod, axusr.aod, axsyp.aod and axapd.aoi

To solve the problem i have to restart the aos service to regenerate axapd.aoi (if i restart the service this file not regerate, i have to stop the service and after start it).

Anybody know how to solve this problem??? Is the problem relationated to my cluster service?, or is related to application?

Thanks
