Solutionyou can add disks smaller size than 50 GB. the number of disks to be added is limited by "Max PV" in the vgdisplay output. Good luck.

- Yes, you can add any size of disk, smaller or larger than 50GB (smaller no problem, larger is limited to ( PE_Size * Max_PE_per_PV) value.
>vgQAECC:
>Max PE per PV 43521
# it will support #2720 PV size. with 64MB PE.
-in your case, Max PE per PV is 43521
check PE size as well:
# vgdisplay vgQAECC | grep "PE Size"
- if your PE size is 64, you can add a large disk , theoretically maximum 2720 GB.
Practically/usually the storage assigns lun size max 500GB or 1 TB, so in that case if you are planning to extend the VG with more than 50GB disk, you should be good.
Cheers,
Raj.

Yes, you can add 80GB disk.
Even smallest PE size VG will allow to add max 170GB disks.
