I'm getting alerts that the drive I have OS installed on my Unity server is running out of disk space (third party app alerts). Total size of OS drive is 12G and only 1.2G is free. I couldn't find anything that could be taking up space e.g MDBdata was empty and MTAdata was empty as well. I went ahead and shrunk the databases (Unity_db and Report_db) and their logs as well. I still could not free up more space. Is there a document on CCO that has instructions on freeing up more disk space? Also, is there any documentation on how much of disk space is required for OS intallation and Unity installation? Any help would be greatly appreciated.
