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
