I am trying to find the way to create a physical volume with specific range of extents. Vgcreate command has -s option for this(but this command is for groups). I read the man for pvcreate and did not find anything about setting extent size. Is there any way to create physical volume with specific number of extents?
pvcreate command and setting of extents
lvm
I understand that you want to do is specify the size of physical extent on the physical volume of a volume group.This is defined in the volume group creation (with vgcreate as you indicate), not makes sense to do previously with pvcreate as this will only initialize a disk or partition for use with volumes of group and nothing more, the options offered by this command are regarding a physical initialization.The definition of logical specifications, is managed in the volume group is where the physical extent size is defined.I think the beginning to understand this is to associate pvcreate (physical volume  create) to physical management, ie the disk or partition that physical part and vgcreate (volume group create) with logic management initialized with pvcreate device and this is where define logical specifications as the physical extent size.For reference you can consult the man pages of pvcreate and lvcreate, although I think you have done this already but with another point of view.At least, so as I understand it.
