How to Fix | Virtual SAN Health Alarm 'Performance data collection'' status is Red


Virtual SAN Health Alarm 'Performance data collection'' status is Red

vSAN CLuster ==> Monitor ==> Virtual SAN==> Health ==> Performance Service ==> Performance Data Collection==> 
Stats Gathering ==>  Failed
Stats persistence==> Failed

The causes for this error is unknown but there are two fixes available to this issue,
1)  Restarting the vsanmgmtd and vsanvpd service on all the ESXi hosts in the vSAN Cluster.  There is no impact of restarting these two services on the ESXi, 
/etc/init.d/vsanmgmtd  restart
/etc/init.d/vsanvpd restart
Make sure the service is is running state after the restart, 
/etc/init.d/vsanmgmtd  status
/etc/init.d/vsanvpd status
Post restart of the services retest the vsan health , vSAN CLuster ==> Monitor ==> Virtual SAN==> Health==>Retest and the Performance Data Collection should be green.
2) To resolve this issue, re-enable the performance service from the cluster level
  • a. go to manage > Virtual SAN > Health and performance
  • b. Click “Turn off” in the “Performance Service”
  • c. Ensure that the Perform Service is disabled by refreshing the page. 
  • d. Re-enable the performance and retest the Health check.
  • e. After the service restarts, go back to the vCenter web Client and click the “Edit” button for the Performance Service box
  • f. Select the appropriate storage policy from the dropdown, ensure the “Turn ON Virtual SAN performance service” box is checked and click “OK”
  • g. Confirm that the performance service is turned on and reporting healthy
  • h. Navigate back to the “Monitor” tab and then “Virtual SAN” clicking the on the “Health” section. Click “Retest” to verify that all hosts are contributing stats.
Note:  Always prefer the option (1) because it keeps the Historical vSAN Performance Data and the option (2) will create new Performance stats object and we will lose all the historical data.

How to fix | vSAN CLOMD Liveness - Part I

In the following scenarios, you will see the CLOMD service liveness on ESXi hosts, If any of the ESXi hosts are disconnected, the CLOMD liveness state of the disconnected host is shown as unknown .If the Health service is not installed on a particular ESXi host, the CLOMD liveness state of all the ESXi hosts is also reported as unknown. If the CLOMD service is not running on a particular ESXi host, the CLOMD liveness state of one host is abnormal. The Cluster Health – CLOMD liveness check in the vSAN Health Service, and provides details on why it might report an error.This checks if the Cluster Level Object Manager ( CLOMD ) daemon is alive or not. It does so by first checking that the service is running on all ESXi hosts, and then contacting the service to retrieve run-time statistics to verify that CLOMD can respond to inquiries.  CLOMD (Cluster Level Object Manager Daemon) plays a key role in the operation of a vSAN cluster. It runs on every ESXi host

How to fix | ESXI Virtual SAN Health service installation

I encountered an issue with the ESXi Virtual SAN Health service installation in one of the vSAN cluster, Step 1 : I checked whether all the ESXi hosts are running on the same version or not, VMware ESXi 6.0.0 build-5224934 VMware ESXi 6.0.0 Update 3 on ESX1 VMware ESXi 6.0.0 build-5224934 VMware ESXi 6.0.0 Update 3 on ESX2 VMware ESXi 6.0.0 build-5224934 VMware ESXi 6.0.0 Update 3 on ESX3 VMware ESXi 6.0.0 build-5224934 VMware ESXi 6.0.0 Update 3 on ESX5 VMware ESXi 6.0.0 build-5224934 VMware ESXi 6.0.0 Update 3 on ESX4 They are in the same version so we can go check whether vSAN health VIB  is installed or not. From the KB https://kb.vmware.com/s/article/2109874 , On vSphere 6.0 Update 2 release, none of the other health checks will be conducted until all the hosts are upgraded to 6.0 Update 2 (when running the latest version, vSAN 6.2) release to avoid false alarms.  But we have all the ESXi hosts in ESXi 6.0 Update 3 "Install the vSAN Health Service V

Horizon View Pools stuck in Deleting state

Recently, had an issue with 2 view Desktop Pools that were stuck in Deleting state in horizon view manager. We are running Horizon View 7.2 and this issue happening since View 4.x.

vSAN Component Failure State - Degraded vs Absent - Part I

Failure States of Virtual SAN Components: Virtual SAN  handles failures of the host, network and storage devices in the cluster based on the severity of the failure. When these fail they directly affect the components in the  vSAN cluster.  Virtual SAN has 2 types of failure states for components ABSENT and DEGRADED. According to the component state, it uses different approaches to recover the affected components. Degraded: "A component is in degraded state if Virtual SAN detects a permanent component failure and assumes that the component is not going to recover to working state." Absent: "A component is in absent state if Virtual SAN detects a temporary component failure where the component might recover and restore its working state." An ABSENT state may or not resolve itself over time, but a  DEGRADED state is a permanent state. From the above image, left side a disk has been unplugged or offline may be reinserted or brought online, Virtual

vSAN Component Failure State - Degraded vs Absent - Part II

Cause and Recovery of the degraded components Scenario 1 Cause : Capacity tier SSD / Magnetic disk drive failure in a Virtual SAN so the disk and all the components stored on the disk is marked as DEGRADED as the failure is permanent. Behind the scenes: If the VM has a policy that includes NumberOfFailuresToTolerate=1 or greater, the VM’s objects will still be accessible. The disk state is marked as DEGRADED and can be verified via vSphere web client UI.  At this point, all in-flight I/O is halted while Virtual SAN reevaluates the availability of the object without the failed component as part of the active set of components. If Virtual SAN concludes that the object is still available (based on available full mirror copy and witness), all in-flight I/O is restarted. The typical time from physical removal of the drive, Virtual SAN processing this event, marking the component DEGRADED halting and restoring I/O flow is approximately 5-7 seconds . Virtual SAN
