  AFM: Lookup file system <fs> fileset <fileset> file IDs
  [559105.-1.-1.-1,N] name testdir1 remote error 13
  
  This is due to root squash enabled.

• Disable root squash would resolve the problem.
  

Problem summary

• If root squash is enabled on a remote filesystem,
  the root user is remapped to a user specified uid
  and AFM fails to access the remote filesystem.

  Fixed the code by introducing new undocumented
  config option afmRootSquashRemoteFS, when
  set to value "no" (default "yes"), allows AFM to
  access remote filesystem as root user
