Lustre mount with SELinux in enforcing causes avc denial messages

Issue

• With SELinux in enforcing mode, lustre filesystems are mounted and labelled as below.

  system_u:object_r:unlabeled_t
  

• This causes various access denied errors, such as,

  avc:  denied  { associate } for  pid=7360 comm="touch" name="xxxx" scontext=user_u:object_r:unlabeled_t:s0 tcontext=system_u:object_r:fs_t:s0 tclass=filesystem
