Description of problem:
B. index_memory_size_mb is required to set but index_memory_size to see it w/ lvs
[root@hayes-01 ~]# lvconvert --yes --type vdo-pool -n vdo_lv --vdosettings 'vdo_index_memory_size=256' -V 20G vdo_sanity/vdo_pool
Unknown VDO setting "vdo_index_memory_size".
[root@hayes-01 ~]# lvconvert --yes --type vdo-pool -n vdo_lv --vdosettings 'vdo_index_memory_size_mb=256' -V 20G vdo_sanity/vdo_pool
WARNING: Converting logical volume vdo_sanity/vdo_pool to VDO pool volume with formating.
THIS WILL DESTROY CONTENT OF LOGICAL VOLUME (filesystem etc.)
The VDO volume can address 2 GB in 1 data slab.
It can grow to address at most 16 TB of physical storage in 8192 slabs.
If a larger maximum size might be needed, use bigger slabs.
Logical volume "vdo_lv" created.
Converted vdo_sanity/vdo_pool to VDO pool volume and created virtual vdo_sanity/vdo_lv VDO volume.
