[linux-lvm] Can't create thin lv

[Marc MERLIN]

Howdy,

Kernel 4.17, trying thin LV for the first time, and I'm getting this:
gargamel:~# lvcreate -L 14.50TiB -Zn -T vgds2/thinpool2 
  Using default stripesize 64.00 KiB.
  Thin pool volume with chunk size 8.00 MiB can address at most <1.98 PiB of data.
  /dev/mapper/vgds2-thinpool2_tmeta: open failed: No such file or directory
  Failed to activate new LV.

any idea what I should try next?

gargamel:~# vgdisplay
