We have SQL 2016 AlwaysOn with 2 Nodes (Primary+1 Secondary)
We had some issue with 3rd party backup tool, so team is working on that.
The issue is in Primary Log Drive size is 5 TB and Secondary 4 TB (Requested to increase additional storage But takes time)
Now my question is, due to issue with Backup tool the log backup is not happning.
What happens if log drive is secondary is full?
