    Description

      Lustre mounts do not support SELinux context options to allow applying an SELinux context across the entire mount.

      Steps to Reproduce

      1. Install CentOS 6 based Lustre client with default SELinux configuration
      2. Attempt to mount Lustre volume with SELinux context

      # mount -t lustre -o context=system_u:object_r:user_home_t:s0 mds@tcp:/testfs /mnt/
      

      3. Error message is produced:

      mount.lustre: mount mds@tcp:/testfs at /mnt failed: Invalid argument
      This may have multiple causes.
      Is 'testfs' the correct filesystem name?
      Are the mount options correct?
      Check the syslog for more info.\
      

      Syslog messages:

      LNet: Added LNI 192.168.122.120@tcp [8/256/0/180]
      LNet: Accept secure, port 988
      LustreError: 152-6: Unknown option 'context="system_u:object_r:user_home_t:s0"', won't mount.
      Lustre: Unmounted testfs-client
      LustreError: 1265:0:(obd_mount.c:1342:lustre_fill_super()) Unable to mount  (-22)
