Lately I’ve been running some Storage Spaces Direct labs on VMware workstation. Part of doing labs means testing things until something breaks and as a countermeasure I tend to create snapshots frequently. Now this led me to an issue that I haven’t seen anyone write about online. It turns out Read more…
Just a small ESXi Pro tip this time. I recently had a host that was experiencing issues and the management services were unresponsive. This is a major problem for troubleshooting as the esxcli commandset won’t work anymore at this stage. Now by accident I came across a tip from the Read more…
With the worldwide outbreak of the coronavirus the Folding@home project has seen a massive influx of new users donating their computer’s idle CPU cycles to run simulations of protein dynamics in order to help find treatments for diseases such as coronavirus, cancer, alzheimer’s, and more. The people of VMware were Read more…
Recently I’ve been involved with a project that required the use of physical mode raw device mappings (pRDM) on vSphere. We weren’t thrilled with the prospect to deploy these pRDMs. Now why would that be you might ask? Well, as a cloud service provider you want maximum agility when it Read more…
Quick post of something I ran into this week. When creating new VMs it makes sense to create disks that have a certain size in GB. But sometimes when migrating workload from one platform to another you might see some funky hard disk sizes like this. {@{Name=Hard disk 1; CapacityGB=49,875}, Read more…
We recently noticed some hosts in our environment that show an alert triggered by ‘Status of other host hardware objects’. Upon further investigation it turned out that this was caused by the system event log (SEL) that is about to run out of space. Now if you don’t mind not Read more…
Recently I had to do just that when a customer I recently on-boarded to our vSphere platform was having issues creating a VSS-aware backup. Even a quiesced snapshot command failed with an error. This issue took quite some time to investigate. And I was lucky enough to have a support Read more…
Recently I had to upgrade a vCenter Server Appliance with embedded PSC from version 6.5 U2e to 6.7 U2c. It seemed a pretty straightforward process like the upgrades I’ve done before. But this time the upgrade failed because of an issue with the PostgreSQL database. I examined the logfiles and Read more…
I found that especially when you migrate Windows vCenter servers to the VCSA you might end up with a deployment size that is less than optimal. Some people say; don’t worry, it’s just thin provisioned. But I’m an old-school guy and I like to keep things neat and simple. The Read more…
Sadly I didn’t make the cut back in March. But I made it this round. I’m honored to be accepted in VMware’s vExpert program. And I will continue to support the vCommunity by blogging at vCloudvision.com which is now 100% powered by vExperts. ?
