The following issues apply to the Solaris Express 7/05 release.
Directories might erroneously appear to be empty after you upgrade an NFSv4 server from the Solaris Express 6/05 release to the current release. Furthermore, your applications might encounter EACCESS errors.
Workaround: To prevent these errors, perform one of the following options.
Unmount and then remount the client file system after upgrading. If unmounting fails, you might need to forcibly unmount the file system by using umount -f. For file systems that are mounted automatically, you can remount the client file system with the command automount -u.
Reboot the client.
Remounting the file systems is not required if you directly upgraded to the current Solaris Express release, starting with Solaris Express 7/05, from either of the following releases:
Solaris Express 4/05 or previous Solaris Express releases
Solaris 10 OS
