How does LVM provide erased storage?

Hi,

I wonder how LVM makes sure to not expose data written in a previous qube when providing storage to another qube.

Any idea where I could find some documentation about this?

IIUC this is controlled by the /etc/lvm/lvm.conf option thin_pool_zero, enabled by default. See the “Zeroing” section in lvmthin(7).

this is exactly what I was looking for, thanks!
