Doc Text When using NFS shared storage for Nova instance storage - it is advisable to mount the share with noac option (see NFS man page for more details), to prevent file attribute caching by the NFS clients. This will enable migration and resizing instances between compute hosts that use the shared storage.

When using NFS shared storage for Nova instance storage, it is advisable to mount the share with the noac or the lookupcache=none option (see NFS man page for more details), to prevent file attribute caching by the NFS clients. This will enable migration and resizing instances between compute hosts that use the shared storage. Both methods have performance penalties, but setting the lookupcache=none option seems to be faster.
