Recreate a missing VMDK descriptor file April 12, 2016

Posted by General Zod in Tech, VMware.

I needed to expand the disk sizes on one of my VMs, and encountered an odd problem.  Under the VM Settings, all of the disk sizes were reading as 0 MB.

zero-mb

Honestly, I have no idea what happened, but it seemed that the VMDK descriptor files had disappeared.  I don’t believe that it would have been done maliciously, yet I can think of no reason why it would have “just happened”.  Regardless, the problem exists, so what to do about it?

OK.  Well, it has been several months since I’ve had anything worth talking about on my little blog… but today, something happened that made me very grateful that I no longer do workstation support as my primary function.

Occasionally I’ll start getting VMs that stop getting backed up using VDP 5.5.  They won’t even attempt a backup the next day either.  I’ll kick off an immediate backup which immediately fails, with the error:

An unexpected error occurred with the following error code:  10058.  More information may be available in the client logs which can be downloaded from the configuration application.

So you’re deploying the VMware Data Protection product, and one of your VMs won’t backup.  Checking the failed task, you see the error “Operation failed due to existing snapshot.”

So last night I got a call from one of our SAN guys.  He had needed to upgrade the Volume Manager app on SERVER6, and proceeded to do what he needed to around 7pm.  After his upgrade, he noted that all of the File Shares had disappeared from SERVER6… so he called me looking for assistance.

Building a new vCenter onto a Distributed Switch July 10, 2012

Normally, I would keep my vCenter on the default Simple vSwitch so that it rides on the same VLAN that the ESXi Hosts exist on.  When you’re planning your environment, it’s always wise to keep the old KISS adage in mind:

Keep It Simple, Stupid!

Well… recently, I had a customer who had separated all of their ESXi Hosts to a dedicated VLAN, and had (due to some remote access rules that were put in place for another customer) placed their vCenter on a separate VLAN accessed via a PortGroup on a Distributed vSwitch which leveraged trunking ports.  This provided a small challenge…

Copy VM between two vSphere environments February 8, 2012

Recently, I had a situation that required me to move a VM from one vSphere 4.1 environment to another of the same release.  The identical vSphere versions was the only thing that these two environments had in common.  They are using different vCenters, different storage, different networks, etc… and security dictated that we could *NOT* link the two environments together.  So how does one move a VM from one unique environment to another?

Which physical NIC is my VM using? June 23, 2011

Recently, I was having an issue in which some of my VMs would intermittently become unreachable across the network.  Looking in vSphere, there were no problems reported with the physical NICs nor with the virtual networking.  Everything was configured OK, so what was the problem?

Can’t Discover ESXi using EMC Control Center May 15, 2011

Since VMware has announced that 4.1 will be the last revision of ESX, I’ve started migrating our VMware Hosts to ESXi… and since I’d just acquired a new DL580 G7, I decided that it would be the first ESXi Host.  So when it came time for our SAN Admin to discover the host via the EMC Control Center, we were presented with the following error:

Not able to connect to host <SERVER.DOMAIN.COM>.  SSL certificate verification failed.

EMC support had the answer…

The Best Career Move I Ever Made May 11, 2011

Back in 2004, I was hired by a rather large corporation to do the Systems Engineering for one of their sites.  One of the first things I’d asked for were details on deployment standards, so that I could make sure that any new systems were being deployed properly.  My manager pulled me aside and explained to me that our site was what was known as a “Delivery Center” that was separate from the company’s global network and were used to host any customer facing servers.  Unofficially, this meant that we were the “black sheep” of the company… and I was instructed by my manager to “make it up as I go”, because we weren’t held to the same standards as the other sites.
