vSphere Datastore Last Updated timestamp – Take 2

I referenced this in an earlier post, but we continue to have datastore alarm problems on hosts running 4.0U2 connected to a 4.1 vCenter. In some cases, the timestamp on the datastore does not update, so it’s not just the alarm having a problem but also the datastore timestamp. As a stopgap measure, we scheduled a little PowerCLI script to automatically run to ensure all of the datastores are refreshed. We then accelerated our upgrade plans to quickly eliminate the problem from our primary datacenter. We now only have it in our DR site, so it’s not critical anymore, just annoying.

if ( (Get-PSSnapin -Name VMware.VimAutomation.Core -ErrorAction SilentlyContinue) -eq $null )
{
    Add-PsSnapin VMware.VimAutomation.Core
}
 
Connect-VIServer yourserver.foo.com
$ds = Get-Datastore
foreach ( $dst in $ds )
{
   $dsv = $dst | Get-View
   Write-Host "Refreshing "$dsv.Name   
   $dsv.RefreshDatastore()
}

vSphere Datastore Last Updated timestamp

We encountered issues that mysteriously appeared after a patching window on our vCenter server. We had just upgraded to vCenter 4.1 earlier in the month and this was the first time the server had been rebooted since the upgrade.

After reboot, the Last Updated timestamp on all datastores was stuck at the time the vCenter service came online. None of our disk space alarms worked because the datastore statistics were not being updated.

We noticed that the problem only appeared on the 4.0 U2 hosts – datastores connected to 4.1 clusters had no problem.

VMware support acknowledged the timestamp update issue as a problem in 4.0 U2 that was partially addressed in 4.1 and fully addressed in the soon-to-be-released 4.1 U1
