physical extent
The fixed-size unit, 4 MiB by default, in which LVM hands out a volume group's space.
In more detail
Every logical volume is a whole number of extents, so sizes round up to the extent size. vgcreate -s chooses the size when the group is created, and lvcreate -l asks for a number of extents instead of a size.
Example
vgcreate -s 8M vgdata /dev/vdbRelated terms
- logical volume — A block device carved out of a volume group, which you format and mount like a partition but can resize later.
