In Parallels Plesk Panel migration, backup and restore logs located in
/usr/local/psa/PMM folder keep filling up all the free space on the server.
Is it safe to delete/rotate the logs?
You may manually remove log files from the
msessions/ subfolders, but first make sure that no tasks are running on the server. To do that verify that tasks subfolder is empty:
# ls -l /usr/local/psa/PMM/tasks/
If you see a different output, it means that some tasks on the server are either in progress or have completed with errors and require your attention. You may search for running or failed tasks in Plesk Panel > Tools & Settings > Migration Manager or Backup Manager .
