Dom0 fails to update and says it hasn't enough storage

Unfortunately, this didn’t help because it only deleted a few MB of logs. However, this did help:

sudo lvresize --size 40G /dev/qubes_dom0/root
sudo resize2fs /dev/mapper/qubes_dom0-root

I increased the storage size of dom0 from 20 GB to 40 GB, but I got a warning:

WARNING: Sum of all thin volume sizes (1.60 TiB) exceeds the size of thin pools and the size of the whole volume group (<952.85 GiB).
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.

Can I just ignore that, or do I need to do something?
