Setting extent size with vgextend?

[MimCom]

Trying to migrate a vg to a larger array, using the following sequence:

pvcreate /dev/newarray
vgextend pve /dev/newarray
pvmove /dev/olddevice
vgreduce /dev/olddevice

But the new vg ends up with nowhere near the capacity of newarray. It appears that initial install (on a small disk, while waiting for the new hardware to arrive) used 4mb extents and I will need more like 64mb to accommodate newarray's capacity.

There is an option in vgcreate to specify the extent size, but I do not see any option in either pvcreate or vgextend to specify the extent size. Did I miss something?

--thanks

But the new vg ends up with nowhere near the capacity of newarray.

What sizes do you get?

Old (remaining space on disk) was 264G with 747M in use.
New (~2TB array) shows 92G with 747M in use.

No idea. What command causes the shrink?

Appeared after the vgreduce completed. Ended up rebuilding the entire system - some combination of RAID driver issues and Proxmox installing grub on the wrong drive seems to have been the genesis.
