·         The size of logical volume depends on size of Physical Extend ( PE ) and size Logical Extend (LE).

• It is possible to define size of PE/LE during physical / logical device creation.
• The default PE/LE size if 4MB.
• If the size of Physical Extents is increased, there are almost no limits for size of LVM.

·         Following table shows the size limits for different architectures using the default PE/LE size.

• There may be additional limitations on boot devices above and beyond the LVM limits themselves.

Architecture	RHEL 5	RHEL 6	RHEL 7
32-bit	16TB	16TB	-
64-bit	(theoretical) 8EB	(theoretical) 8EB (tested       ) 100TB	(theoretical) 8EB (tested       ) 500TB
