SDDC Manager root Partition Cleanup

This tutorial will show you how to perform the SDDC Manager / root Partition Cleanup using the Command line.

Performing an SDDC Manager /root partition cleanup is crucial in VMware Cloud Foundation environments, especially if the root partition is nearing capacity. The steps below help you safely clean up the / root partition from the command line.

Step 1: The safer side recommended to take SDDC Manager appliance virtual machine snapshot without memory.

Step 2: Open PuTTY and connect to the SDDC Manager appliance.

ssh vcf@<sddc-manager-ip>

!Then switch to root using su

#su

Replace <sddc-manager-ip> with the actual IP address or Hostname of your SDDC Manager.

Step 3: To identify the usage of the SDDC manager file system:

#df -h

Focus on the / or root partition. If it is above 80% utilization is considered a warning and above 90% is considered critical, proceed with the cleanup.

Step 4: First check for Large Files and SOS bundle consuming the disk.

! If an SOS bundle is present on the SDDC Manager, it is safe to remove it. This blog post covers how to Generate SDDC Manager Support Bundle through UI and CLI.

#ls -ltrh /var/log/vmware/vcf/sddc-support/

! Use rm command to remove the file sos-<GENERATED-DATE-TIME>.tar.gz
# rm /var/log/vmware/vcf/sddc-support/sos-<GENERATED-DATE-TIME>.tar.gz

Replace sos-<GENERATED-DATE-TIME>.tar.gz with the actual file from the ls ouput your SDDC Manager.

! If no SOS bundle is present in the /var/log/vmware/vcf/sddc-support/ path, follow the commands below to clean up.

# journalctl --disk-usage

! Above the command shows disk usage of journalctl logs.

#journalctl --vacuum-time=1d

! Above the command safely clean up the journalctl logs.

Refer to the screenshot.

Note: If Step 4 doesn't reduce the disk usage / Partition follow Step 5.

Step 5: Identify large files and unnecessary logs

! The below command identifies the top 30 files and folders consuming space

#du -ah / | sort -rh | head -n 30

! Caution: Only remove tar.gz and .log files. Avoid deleting system-critical files or folders that will break the SDDC Manager. Only recommended to remove Journalctl logs and SOS bundle. If you're unsure contact Broadcom support always.

#find /var/log -type f -name "*.log" -mtime +30 -exec rm -f {} \;

! The above command identifies 30 days aged files and folders consuming space.

! /var/tmp temp files are auto-removed during the reboot if you find any such take a reboot of the SDDC manager.
