Hi, I've been wondering about something. I only have 25G allocated yet ZFS already cached 140G on my SSDs in just one night. Is this expected behavior? What happens if it's full, will it auto overwrite stuff or will it start to take system memory? I didn't configure anything as to how much memory L2ARC can use, is there any place to do that? I tried to google on it but no clear answers.
Thanks!
Thanks!
