Issue/Introduction

Title: Edge disk usage very high
Event ID: edge_health.edge_disk_usage_very_high

Alarm Description:

• Purpose: To inform the user that a disk partition of the Edge has reached very high levels.
• Impact: The impact depends on the partition that has high usage. If the root partition has high usage then system stability may be affected. Other partitions becoming full, such has the config, log, or image partitions, may impact functionality related to those partitions.

Environment

VMware NSX-T Datacenter
VMware NSX

Resolution

Steps to Resolve
For 3.0.0 and higher

Recommendation Action:

• Examine the partition with high usage and see if there are any unexpected large files that can be removed. The image partition contains the NSX file-store, so you can use the 'get files' commands to check for excessive disk usage by support bundles, tcp dump files, or other large files. Other partitions will require root access (start engineer) to inspect them for large files.

Maintenance window required for remediation? No

Additional Information

If you need to open a Broadcom support request, be sure to note the file system usage (df -h) on the affected appliance. You could also use the du command (du -xaBM 2>/dev/null  sort -nr |head -n 50 |more) from within the affected file system to provide a better understanding of what might be consuming excessive disk space.
