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 …
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}, @{Name=Hard disk 2; CapacityGB=49,875}} |
Fixing this for …
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 …
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 …
Recently I’ve been getting an error on one of my replication jobs in one of our Veeam environments. The error message was a bit vague, and to be honest, I’ve never seen it anywhere behore. The error message was: If you browse to your log file location, usually under: You …
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 …
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 …
The other day I was patching a couple of hosts on one of our environments. All worked out fine until I got one host that refused to update from vSphere ESXi 6.5 U1 to ESXi 6.5 U3. Throughout the day this host actually gave me loads of different errors. In …
Recently we have been having (extremely) slow boot times for a couple of hosts that we’ve been using for a new customer. We actually didn’t really notice this in the beginning, until we added hosts to the existing cluster and the reboot for that host took over 3 hours! The …
In a previous post I posted back in december 2018 (CLICK HERE) we experienced issues while using on of our Veeam 9.5U3a environments together with VMware vSphere 6.7 U1. Since time has passed and Veeam has released support for vSphere 6.7 U1 (Veeam 9.5 U4) and vSphere 6.7 U2 (Veeam …
