If you are seeing disk nearing capacity messages in the panel it is important that you resolve this by clearing space to prevent problems with the MediaCP. You can confirm disk utilization by running df -h on your system. You should ensure there is at least > 10% space available on the root partition (/).
Recordings
If you believe this may be related to recorded videos, then you can review the disk utilization of the MediaCP Content path at /usr/local/mediacp/content/. You can get an idea of where space is being used by running du --max-depth=1 -h /usr/local/mediacp/content/. Video files for MediaCP Video are typically stored in /usr/local/mediacp/content/user_{id}/NginxRtmp/{port}_{service_id}/ where {id}, {port}, and {service_id} are relative to a particular service. The following command can be used to identify which specific MediaCP Video (NginxRtmp) services are utilizing the most space:
du --max-depth=0 -h /usr/local/mediacp/content/user_*/NginxRtmp/*/media/
Backups
Backups can also take up disk space and you can check their usage here:
du --max-depth=0 -h /backups/
If backups are the culprit removing extra backups if they are not needed will help, once the space is clear review the automatic backup settings in the panel or add a dedicated backup disk to your server: https://www.mediacp.net/doc/admin-server-manual/backup/backup/
