LVCB (Logical Volume control block)
Logical volume control block (LVCB) contains important information about the
Logical volume, such as the number of the logical partitions or disk allocation
Policy. Its architecture and location on the disk depends on the type of the
Volume group it belongs to. For standard volume groups, the LVCB resides on
The first block of user data within the LV. For big volume groups there is
Additional LVCB information in VGDA on the disk. For scalable volume groups
All relevant logical volume control information is kept in the VGDA as part of
The LVCB information area and the LV entry area.
