Unable to collect vCenter Server log bundles due to /storage/log full

Products

• VMware vCenter Server

Issue/Introduction

Symptoms

• Failed to collect log bundles from vCenter Server using the vSphere Client
• /storage/log is showing high usage

Environment

VMware vCenter Server 7.x
VMware vCenter Server 8.x

Cause

When collecting log bundles from vSphere Client, log bundles are generated in the /storage/log.
Therefore, the log bundle generation process fails due to insufficient space in /storage/log.

Resolution

If /storage/log does not have sufficient space, collect log bundles using the following method.

GUI

1. Access the following URL in your browser
   https://<vCenter Server FQDN>/appliance/support-bundle
   
2. Enter the root credentials for the vCenter Server Appliance
   
   
3. Verify the download in your browser.

CLI

The vc-support command generates log bundles in /storage/log by default, but you can specify the destination for log bundle generation using the -w option.

1. Log in to vCSA using SSH
   
   
2. Enter the shell command to access the Bash shell.
   shell
   
   
3. Check the partition with the most free space (e.g., storage/core)
   df -h
   
   
4. Specify a partition with free space to collect log bundles
   vc-support -w /storage/<partition name>
   
   Example command
   vc-support -w /storage/core
   
   
5. Download log bundle
