Proceedure

Log onto a CVM of the cluster in question with the ‘nutanix’ account. The default password is ‘nutanix/4u’ but this may have been changed in your environment.

Check the /home usage for all the CVM in the cluster with the following command

allssh df -h

Output will look like this for each of the CVMs in the Nutanix cluster

Use the commands below on the CVM to remove old log files and installer files from /home on all the CVMs on the cluster

allssh rm -rf /home/nutanix/data/cores/*
allssh rm -rf /home/nutanix/data/binary_logs/*
allssh rm -rf /home/nutanix/data/log_collector/*
allssh rm -rf /home/nutanix/data/ncc/installer/*

Once all the command have been run rerun the ‘allssh df -h’ and check the output and ensure the /home is under 80% now for each of the CVMs.

If the /home is still above 80% contact Nutanix support for further troubleshooting.
