Size thresholds
===============
-A directory fragment is elegible for splitting when its size exceeds
+A directory fragment is eligible for splitting when its size exceeds
``mds_bal_split_size`` (default 10000). Ordinarily this split is
delayed by ``mds_bal_fragment_interval``, but if the fragment size
exceeds a factor of ``mds_bal_fragment_fast_factor`` the split size,
100000. Increasing this limit may lead to oversized directory fragment
objects in the metadata pool, which the OSDs may not be able to handle.
-A directory fragment is elegible for merging when its size is less
+A directory fragment is eligible for merging when its size is less
than ``mds_bal_merge_size``. There is no merge equivalent of the
"fast splitting" explained above: fast splitting exists to avoid
creating oversized directory fragments, there is no equivalent issue
