As of Release 3.3.1, Oracle VM does not support NFS V4 read/write delegation. NFS V4 delegation must be disabled on network storage devices used for Oracle VM.
For example, to disable read/write delegation on a NetApp filer,
go to the NetApp console. Select FilerView
, then
click NFS->Configure
. Select no
on the following two pull-down menus:
Enable Read Delegation on NFS Version 4
Enable Write Delegation on NFS Version 4
