The folder /var/atlassian/application-data/jira/export used 32 GB disk space. This folder store daily backups.

I removed some of the older backups last last year, restarted the server, that fixed the problem.

To avoid this happening again, set a cronjob

vi /usr/serverok/clean.sh

Add

#!/bin/bash

/bin/find /var/atlassian/application-data/jira/export/ -type f -mtime +60 -name "*.zip" -delete

This will delete files older than 60 days.

Set it to run daily with crontab -e

@daily  /usr/serverok/clean.sh > /dev/null 2>&1
