"Virtual SAN Disk Balance" warning alarm during vSAN health check (2148484)

  • 0 Ratings
Language Editions


  • The vSAN health check reports the warning:

    "Virtual SAN Disk Balance"

    : This warning occurs only in the vSAN stretched cluster configuration.


This issue occurs because the disk usage in witness is 0.

When computing the disk balance status, the disks are imbalanced because the disk usage in witness is nearly 0.


This is a known cosmetic issue in VMware vSAN and can be safely ignored.

To avoid this issue, disable the VC alarm for disk balance health check:
  1. Navigate to VC > Monitor > Issues > Alarm Definition.
  2. Disable the vSAN Health Alarm:
     "VSAN Disk Balance"


This is a cosmetic issue and can be safely ignored.
