Oracle VM Manager : OVMRU_002024E Cannot perform operation

Error message : OVMRU_002024E Cannot perform operation


Solution :
As specified in the error message:

File Server: NAS_NFSDS01, has invalid exports. Export: /vol/vol0, is contained in export: /vol/vol0/home. Remove one of those exports on the file server, and then refresh the file server to clear the error

This is described in the release notes - http://docs.oracle.com/cd/E50245_01/E50246/html/vmrns-storage.html#vmrns-refreshing-nas-invalid and the workaround generally is:

"do not export top level file systems in the NAS-based file server's exports file"

The error in this case explicitly tells you that the export /vol/vol0 is contained in the export /vol/vol0/home and you need to remove one of those exports and then refresh the file serv.
