AIX系统pv限制

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�Cbit 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
