Good point, but may I point out this is by design. The default disk type that vmkfstools assumes when the ‘-d’ option is not explicitly used is zeroedthick. This is true of extend as it is true of...

Thank you Satyam. Always great to hear from you. We think this may be a concern when one tries to grow an FT or MSCS VM, both of which need to use eagerzeroedthick. We’re having some conversations...

I am interested specifically in the MCSC piece of this conversation. I have tried and failed to expand a eagerzerothick vmdk while the cluster is running via CLI due to file locks. now I could shutdown...

Hi Nate, Thanks for the comment/question. As you observed, any VM using a VMDK must be powered off before a VMDK can be grown (kb.vmware.com/kb/1007266) This is the reason for the file lock, and...

Ondrej, where did you get the info that this is fixed in 6.0? I can not find anything related in the Changelog and can not test it at the moment.

I opened a support case with VMware and they confirmed this "behavior" (they refused to call it a bug and instead said it was by design), is "fixed" in 6.0. Due to the large amount of code changes...

Thanks, I also opened a case a while ago and received the answer that this is the intended behavior. But i did not receive the update that this is now fixed in 6.0.

Great work VMware. NOT! Now that eagerzeroed vDisks are extended in eagerzero format in 6.0, the VM does hang until the task has finished. That can be a couple of minutes for the extension of some...
