VMWare ESXi shrink thin or thin provisioned disk

Monday, April 9th, 2012

If you’re like me, that is with a very limited cash availability to invest in hardware, you will most likely run out of space pretty fast once you start converting all those virtual machines you got on the desktop to your newly installed ESXi.
Now, you will immediately think, what happened to my thin provisioned disks that made them grow like that? You can google for the answer but let me tell you a better solution than what you will find on the net, which are:
– convert the virtual machine
– use some cdelete or whatever its name is to free up space
– maybe other things that are not as cool

The cool idea is that you can create a new disk, about the size that you need, and copy over the data to the new disk then delete the old one. Either use dd in linkux or whatever diskcopy you can find for windows (easeus has a few solutions) or use a system backup something that will pack up your files and then restore on the new disk.
This beats converting V2V as the hardware will not change.

Create ESXi 5.0 ISO to USB bootable flash stick in windows

Sunday, April 8th, 2012

I just got my hardware for my personal ESXi server (I will go into more detail in a separate post one of these days) and the first thing I noticed when I wanted to plug in my CD-ROM was that the MB had no IDE connector. I don’t have a sata cd-rom nor a usb one, so the next best thing, boot from USB.
Now, there are a lot of cool utilities out there to convert a bootable ISO image into a bootable USB stick, but from the aprox 3 or 4 I tried, only the last one worked. I even tried going manual, applying syslinux from command line, copying files and editing the configs. However, due to the fact that the file names are all in uppercase on the CD, the bootloader was not able to fins the kernel and stuff.

So, long story short, I found the following article which works for ESXi 5.0:
