Avamar Grabage collection troubleshooting

If your garbage collection stop working, you know you are in trouble. Your grid will eventually fill up, and die a slow and painfull death.
Use the following commands from the utility node to try and diagnose the problem:

dumpmaintlogs --types=gc --days=7
In case you see along the lines of "<4203> garbage collection skipped because backups in progres", please verify which nodes are allowed overtime, they are certainly creating problems.

Nodes that are allowed overtime can be seen with:
mccli client show --recursive=true --verbose=true | grep -v "No overtime allowed"


If you'd rather just have garbage collection kill the sessions preventing it from running, just type:
avmaint sched gc --ava --kill=300 --permanent

gc_report
less /usr/local/avamar/var/cron/gc.log
