Hi guys ,following message apears whean creating new VM.

WARNING: You have not turned on protection against thin pools running out
of space.
WARNING: Set activation/thin_pool_autoextend_threshold below 100 to trigger
automatic extension of thin pools before they get full.
Logical volume "vm-127-disk-0" created.
WARNING: Sum of all thin volume sizes (<3.36 TiB) exceeds the size of thin
pool pve/data and the amount of free space in volume group (763.07 GiB).
TASK OK

Please confirm if my understanding is correct: If my current running VMs
storages grow to configured limit , I will reach server physical limit
(3.36TB).
So , what is the autoextend_threshold for ? Any advice about that ? Thanks.
