FreeBSD 12 bumps this limit to 1024. This means that you should be wary of automatic snapshot schemes that bump up toward this limit. Otherwise, the snapshots will not appear in shadow_copy2. One way to quickly tell if you're hitting the limit is to "cd" into the snapdir and "ls -l". If you've hit it then it will fail with ENAMETOOLONG.
I'm actually on Debian 10, Proxmox standard installation. I'm not hitting the limit as far as I can tell. Do you know how I can find out where the mistake is? Is there an easier way to troubleshoot this? ??????? Original Message ???????

Hi Jeremy, any additional thoughts on troubleshooting the below? Did anything stand out to you from the logs? I can't figure out why shadow_copy2 is just not working as it should. ???????
