Glance mount point is always set NFS v4 in Openstack deployed by Director

Solution Verified - Updated -

Issue

  • Glance mount point is always set NFS v4 in Openstack deployed by Director

  • After stack deployment, the nfs4 parameter is set in the mount point.

  • storage-environment.yaml :
  ## Whether to make Glance 'file' backend a NFS mount
  GlanceNfsEnabled: true
  ## NFS share for image storage, e.g. '192.168.122.1:/export/glance'
  GlanceNfsShare: "<IP of NFS server>:/glance"
  ## Mount options for the NFS image storage mount point
  GlanceNfsOptions: "rw,sync,vers=3,context=system_u:object_r:glance_var_lib_t:s0"
  • However after deployment, the fstab entry adds nfs4 for glance mount point.
  • /etc/fstab mount point on controller node
