lvs command cannot find LVM partitions, what tool to use to interact with these partitions?

Question

When doing a fdisk -l there are two "Linux LVM" partition, but using lvs returns nothing and lvmdiskscan returns "0 LVM physical volumes".

What tool should I use to interact with these partition ? (Shrink, resize etc)

sudo fdisk -l gives

pvscan returns

No matching physical volumes found

vgscan returns

Reading volume groups from cache.

vgs and pvs returns nothing

When doing fdisk -l from an Ubuntu 14.04 live CD, the partitions are reported as Linux and not Linux LVM, with an ID of 83 instead of 8e, may it be that the tools installed on the arch installation wrongly detect the partitions as LVM, and LVM tools knows they are not LVM partitions and ignore them ?

Please add the output of `pvs` and `vgs` to the body of the question as well. — dawud, May 30 '16 at 16:46
Please run the commands `pvscan` and `vgscan` and then paste the output of `pvs` and `vgs` as suggested above. — Pablo Martinez, May 30 '16 at 17:29
Nope, fdisk is not wrong. But fdisk displays only partition type which is set to "linux lvm" (0x8e) for them, that's all. Were there ever any physical volumes created there? — Martian, Jun 13 '16 at 12:30

lvs command cannot find LVM partitions, what tool to use to interact with these partitions?
