It is safe to remove the contents of the /opt/Deployments/lrs/repository/VERSIONS/xml_content/layer7/APIs/api-availability.xml directory on the filesystem, but directory itself must be retained. 

To immediately free up disk space and inodes on the API Developer Portal, the following steps should be performed:

1.     Log on to the API Developer Portal node as the root user.

2.     Run this command: # find  /opt/Deployments/lrs/repository/VERSIONS/xml_content/layer7/APIs/api-availability.xml/ -type f -mtime +2 -delete

3.     Verify the available disk space and inodes using the commands listed below.

A.     Disk space: # df -h

B.     Inodes: # df -i

Additional Information


To prevent this issue from occurring, it is necessary to implement a cron job which will remove unnecessary files on a scheduled basis.

1.     Log on to the API Developer Portal node as the root user.

2.     Run this command: # crontab -e

3.     Type "i" to begin insert mode, then create a new line which reads as follows: 2 2 * * * find /opt/Deployments/lrs/repository/VERSIONS/xml_content/layer7/APIs/api-availability.xml/ -type f -mtime +2 -delete

4.     Save the crontab by using the [Esc] key, and then entering: :wq!

Verify by running this command: # crontab -l
