Newly created snapshots will occupy some data and metadata space in LVM. So
the more snapshots you have, the more space will be utilized.

Yes, I understand that. The question is how to get snapshots error out
instead of breaking LVM completely. Is there any way to tell snapshots to
fail if after creating that snapshot pool won't have certain amount of free

As of now, No. There isn't any option to schedule a removal of the

Auto-delete is not suited for proper snapshot handling (i.e. certain number
of hourly/daily/monthly snapshots kept) but --mode=script would do.
Thank you!
