5.3. Regain Disk Space

If your disk usage is growing too fast and free disk space is running out, you have several options:

  1. Increase the size of your disk

  2. Delete files that are not needed for operation (i.e. safe to delete)

  3. Delete files that are used by ASGARD Management Center but might no longer be needed

5.3.1. Safe-to-Delete Files

The following files are safe to delete. They are not needed for ASGARD to operate.

  • /var/log/asgard-management-center/*.gz

They are only kept on the system if needed for further processing. For example, they may be used to save or send log files to another system. If you do not need or plan to use these files, you can delete them. If you are unsure, copy them to another system before deleting them.

  • /var/lib/asgard-management-center/downloads/* (except current day)

The files in this folder are generated only for temporary downloads from the UI and are not needed after the download has finished. The directory uses a year/month/day substructure. It is safe to delete any files older than the current day.

5.3.2. Potentially Unneeded Files

  • /var/lib/asgard-management-center/scan-results/*.gz

  • /var/lib/asgard-management-center/generic-results/*

  • /var/lib/asgard-management-center/remote-console/protocol/*.gz

The listed files are the results of THOR scans (scan-results), tasks (generic-results), and remote console sessions (remote-console). They are not needed for ASGARD to function, but the data is visible and available for download in ASGARD. Deleting these files will not break ASGARD, but you lose the information provided by the files. If you need the disk space and cannot increase the disk, delete files older than a given date that you no longer need. You can do this with a find-remove combination on the command line:

root@asgard:~# find /var/lib/asgard-management-center/<directory> -mtime +<days> -print0 | xargs -0 -r rm

Where <directory> is one of scan-results/*.gz, generic-results/*, or remote-console/protocol/*, and <days> is the number of days you want to keep. Files and folders older than <days> days will be deleted.

Example to delete task results older than 30 days:

root@asgard:~# find /var/lib/asgard-management-center/generic-results/* -mtime +30 -print0 | xargs -0 -r rm
