VSAN VM Storage Policy failed to retrieve data from the server

 

Last week I got into an issue in my lab environment where some of my VM's under the vSAN 7.0 cluster was unable to migrate from one ESXi host to another ESXi host.

During vMotion the VM from one host to another host,  I was getting an error that the storage profile missing.

On validating the VM storage profile from vCenter which is on 7.0 it's identified that none of the VM storage policies was visible there and flashing error " Failed to retrieve data from the server".

vCenter Storage providers were also showing blank as it looks not in sync.

Further, investigating through with the vCenter logs, I identified the below error:

As per the logs, it's showing Failed to register vSAN VP services.

vSAN health services are up and running on the vCenter Server, but found the service log file had a significant size.

--rw-r--r-- l.   1 vsan-health users 8.3G Oct 13 10:14 vmware-vsa-health-service.log

As the vSAN-health logs were occupying a significant amount of space of 8.3 GB on the partition and due to unavailability of space health services were unable to write new logging into /var/log/vmware/vsan-health partition.

To troubleshoot this issue, the below steps were taken into action.

1) Stopped vSAN health services on the vCenter Server.

2) Moved the vSAN health services logs file to other partitions for later reference or you can delete if you don't feel it's not useful for you.

3) Start vSAN health services.  >> Validated the service.log file has been recreated successfully.

4) Restarted SPS services on the vCenter Server.

After applying the above steps, all Storage providers were available again in vCenter Server.

After this, all VM storage profiles were visible as vSAN and VM level also able to successfully managed to vMotion VM from one host to another host.
