Dell NetWorker 19.9 Administration Guide

Insufficient AFTD disk space

When an AFTD runs out of disk space, the current backup is interrupted and the following message displays:

Waiting for more available space on filesystem device-name

Immediately following the message, the action that is associated with the "Filesystem Full — Recover adv_file Space" notification occurs. By default, the action for this notification uses the nsrim command to delete expired save sets. If enough space is cleared, the backup continues. If the recycle setting for the volume is manual, then the expired save sets are not removed from the volume.

The AFTD deletes expired save sets depending on the retention policy and the recycle setting. If sufficient storage space is not available after 10 minutes from when the expired savesets begin deletion, the associated "Filesystem Full—Waiting for adv_file Space" notification action occurs. By default, an email notification is sent to the root user on the NetWorker server on UNIX and Linux, and a message is logged in the media log file in NetWorker_install_path\logs on Windows.

When the notification is sent, and the message is logged in the media log file, the backup stops until space is available for the backup to continue. You can create customized notifications to change and expand how the NetWorker software behaves when an "AFTD Filesystem Full" notification occurs. Custom notifications can also run custom scripts and other programs to expand the capacity of existing AFTDs.

The chapter "Reporting NetWorker Datazone Activities" provides more information about how to configure notifications.
