    Looks like the 'delaylog' option for
      xfs is the problem - no longer supported in later kernels. See
https://github.com/torvalds/linux/commit/444a702231412e82fb1c09679adc159301e9242c

    
    Offhand I'm not sure where that option is being added (whether
      ceph-deploy or ceph-volume), but you could just do surgery on
      whichever one is adding it...
    regards
