My conclusion is this (with my version of kernel and mkfs.ubifs tool):

(Min No. UBI Volume LEBS) = (jrn_lebs) + 3 + (log lebs) + (lpt_lebs) +
(orph_lebs)

And these values can all be determined (or specified) by the
mkfs.ubifs tool by using the verbose -v flag.

This seems to hold true - Does this seem reasonable?

Thanks,
