The first part of a cachevol LV is used for metadata, and the rest of the space is used for data. The division of space between metadata and data depends on the total size of the cachevol. The previous division gave more space than needed to metadata, it was: cachevol size 8M to 128M -> metadata size 16M * cachevol size 128M to 1G -> metadata size 32M cachevol size 1G and up -> metadata size 64M (* if this resulted in over half the LV used as metadata, then half the cachevol would be used for metadata, and the other half for data.) The division of space now gives less space to metadata, it is: cachevol size 8M to 16M -> metadata size 4M cachevol size 16M to 4G -> metadata size 8M cachevol size 4G to 16G -> metadata size 16M cachevol size 16G to 32G -> metadata size 32M cachevol size 32G and up -> metadata size 64M
