VMware ESXi: renaming a VM and VMDK

Posted by jpluimers on 2014/04/09

This turned out to be much more manual work than I hoped: renaming a VM and the VMDK used by the VM in ESXi.

If you prefer to do all steps by hand on the command-line plus two vi sessions for the vmx* files and the main vmdk file: Just one more esxi-guy: How to Rename a Virtual Machine with the CLI in esxi 5.0.

If you have vCenter, you can do it from the guy. Note for Free ESXi users: vCenter is a payed product, but there is a trial of vCenter.

A bit less manual work, but a bit more scripting from the console (if you are comfortable with that) is at Howto: Rename a VM – Yellow Bricks to which you might want to add the script mentioned at Rename multiple files by replacing a particular pattern in the filenames using a shell script – Stack Overflow.

You can also script from vMA or vCLI: VMware KB: Renaming a virtual machine disk (VMDK) via the vSphere Management Assistant (vMA) or vSphere CLI (vCLI).

How can a partition be full if du does not show it is? (via: linux – Super User) #OpenSuSE #btrfs #snapshots

Posted by jpluimers on 2014/04/09

A long time ago I asked this OpenSuSE/Linux question: How can a partition be full if du does not show it is? – Linux on Super User.

With help of the OpenSuSE forums, I did figure out the source of the problem and solution, but I totally forgot to blog about it.

So below it is, just in case SuperUser ever shuts down, or the StackOverflow moderators are taking over SuperUser as well.

But first the comments in the questions about where I found the source and solution:

I found it through the openSUSE forums: it uses btrfs and snapshots. So the snapshots take up a lot of space. And I need to find out a way to delete old snapshots. forums.opensuse.org/english/get-technical-help-here/…

and

I think I found it: nrtm.org/index.php/2012/03/13/…

I wasn’t alone, so here are some more useful links and links from people asking for help:

Need to draw an ASCII diagram? ASCIIFlow is awesome:… (via: Ilya Grigorik – Google+)

Posted by jpluimers on 2014/04/09

ASCIIFlow.com:  Brilliant!

And from the comments PlantUML which generates UML diagrams from text, of which the sequence diagrams can also be generated as ASCII (the others only as images).

Finally there is ditaa which goes from ASCII diagrams to images. The complete circle is done (:

Big Ball of Mud | Jeroen on software

Posted by jpluimers on 2014/04/09

Just bumped into this Big Ball of Mud article by (another) Jeroen on software (this Jeroen is Jeroen De Dauw).

It is a very nice article with annotations on the (very old, but still very prevalent Big Ball of Mud design pattern of which a lot of software projects suffer).

I didn’t know about the design pattern yet, but have seen it in so many places, and even helped quite a few of them to become less big, and contain less mud. If the article and paper are tool long, you can read a WikiPedia BBM abstract.

I’m glad that the .NET/Delphi based suite of projects I landed on recently – though containing quite a bit of legacy – is different. Still a lot of improvements to be made, but it is very manageable.
