Symptoms

The ost.log is larger than 25M on the Data Domain (DD). See How To Access a Data Domain System from an Avamar Server for information about logging in to DD from Avamar and access bash mode.

ls -l /ddr/var/log/debug/ost/ 
-rw-rw-rw-  1 root admin 9.7G Sep 14 06:43 ost.log
 

Reviewing the log rotate configuration confirms that it is not correct:

head -1 /etc/logrotate.d/ost.log
/ddr/var/log/debug/ost {

Cause

The ost.log is not rotating properly due to an incorrect configuration.

Resolution

1. Create a Service Request with the Dell Data Domain support team to assist with review and potential edit of /etc/logrotate.d/ost.log.

2. If the issue is still not resolved, see Avamar: Troubleshooting Data Domain Integration Reporting Errors in the Avamar Administrator UI (Resolution Path)
