VCF Administrator Receiving Error Regarding vSAN Object Health not Re-syncing.

Products

• VMware vSAN

Issue/Introduction

vSAN Cluster reporting 63 objects being queued for resync, due to insufficient cluster resources.

Environment

• VMware ESXi 8.0 Update 3
• 5 Node vSAN Cluster (1 Node Compute)
• OSA
• RAID-5/RAID-6 storage policies

Cause

This issue is occurring due an insufficient number of data nodes present in the cluster to support RAID-6 objects.

Resolution

In order to address this a new RAID-5 policy will need to be applied to the objects, as there are only 4 vSAN Data (and a 5th compute node) contributing to the cluster.

Refer to Administration Using vSAN Policies for further clarification of this process.

Additional Information

Running the following command will report how many objects have a RAID-6 policy, when run on a participating host in the cluster.

• cmmds-tool find --f -python | grep '"RAID_6' -c

         63

This matches the exact number listed in the error, confirming these are the problematic objects.

Querying the file below yielded the RAID-6 objects, from an identification perspective:

• cat localcli_vsan-debug-object-overview.txt | grep -i RAID6

Which provides the object ID, space utilization on disk, as well as RAID policy.
