LVM device size limits

The following limits are the LVM architectural limits. If LVM Bad Block Relocation is required, then PV sizes cannot be larger than 128 GB. For size limitations of specific storage devices, refer to the storage device documentation.

The following size limits are for a 64–bit kernel:

Original VG

PV Limit: 1GB (PP) * 16256 (PPs/PV, factor=16) = 15.9 TB

LV Limit: 1GB (PP) * 32512 (PPs/VG) = 31.8 TB

Big VG

PV Limit: 1GB (PP) * 65024 (PPs/PV, factor=64) = 63.5 TB

LV Limit: 1GB (PP) * 130048 (PPs/VG) = 127 TB

SVG

PV & LV Limit: 128GB (PP) * 2048K (PPs/PV) = 256 PB

The following size limits are for a 32–bit kernel:

All VG Types

PV Limit: < 1 TB

LV Limit: < 1 TB
