[linux-lvm] dm thinp: pool get's bigger than allowd virtual disk

[Stefan Priebe]

Hello list,

i created a thinp device with a maximum size of 100G and an initial size 
of 10G.

I started to copy 100GB to this disk and end up like this:

# lvs
     LV    VG      Attr     LSize   Pool  Origin Data%  Move Log Copy%
  Convert
     disk1 thinvol Vwi-aotz 100,00g pool1         99,96
     pool1 thinvol twi-a-tz 123,86g               80,71

this will waste 123,86g for all the time ?! As i can't use them.

Is this known? Is there a fix / solution?

Greets,
Stefan
