Sometimes it is observed that a master node may have high disk usage, over 80% with no apparent reason. Looking at possible causes, we realized that a database backup was taken daily.
Possible reasons of a daily backup
Configuration --> Database --> Scheduled backups
This can be done automatically via schedule database backup, that was empty, so was not the reason
or because a patch install, and was not possible either this cause because was not installed a patch every day to the appliance.
Confirmed that the configuration in Configuration --> Database --> Scheduled backups shows that no scheduled backup.
So we go to the appliance via ssh to check if cron show any job schedule, sometimes the problem is that even if you do not in GUI, it is running and active in appliance.
CA Privileged Access Manager, can happen in most versions.
To correct the problem it is necessary to gain ssh access to the appliance. Please engage Broadcom support to assist you with this.
Once connected through ssh to the PAM node the following actions will help correct the disk space problem
In this particular example the second line shows a daily backup scheduled at 13:30 which should not be there according to the information in the GUI
To correct this situation, do the following:
This remediation will both allow the disk space to be recovered and it will also prevent a future occurrence of the same problem.
