vSAN File Services fails to create file share with error Failed to create the VDFS File System.

Duncan Epping · Oct 4, 2022 · Leave a Comment

Last week on our internal slack channel one of the field folks had a question. He was hitting a situation where vSAN File Services failed when creating a file share with the error “Failed to create the VDFS File System”. We went back and forth a bit and after a while I jumped on Zoom to look at the issue, and troubleshoot the environment. After testing various combinations of policies I noticed that a particular policy worked, whole another policy did not. At first it looked like that stretched cluster policies would not work but after creating a new policy with a different name it did work. One thing left, the name of the policy. It appears that the use of special characters in the VM Storage Policy name results in the error “Failed to create the VDFS File System”. In this particular case the VM Storage Policy that was used was “stretched – mirrored FTT=1 RAID-1”. The character that was causing the issue was the “=” character.

How do you resolve it? Simply change the name of the policy. For instance, the following would work: “stretched – mirrored FTT1 RAID-1”.

Introducing VMware vSAN 7.0 Update 2 (video)

Duncan Epping · Mar 9, 2021 ·

As you may have seen, today VMware announced the release of VMware vSAN 7.0 Update 2 (and vSphere 7.0 U2 as well of course). I was planning on doing a post on the 7.0 U2 release, but then I figured that I would try to record a video discussing most of the new features and enhancements introduced. Note, I do not cover the full release, I picked the features which I felt deserved some attention. I uploaded the video to my Youtube Channel, make sure to visit it and subscribe, as I will be releasing demos on various features in the upcoming weeks with some more detail where needed. Hope you enjoy it, and again, make sure to like the video and subscribe to the channel!

Duncan Epping · Dec 9, 2020 ·

I recorded a webinar a while back. It was streamed last week, and I figured that as I have the recording here, I may as well share it with you. In this webinar I discuss many of the new features which were introduced as part of vSAN 7.0 U1, features like HCI Mesh, IO Insight, enhanced File Service capabilities, and much more. The session is about 40 minutes long, but of course, the great thing about youtube is that you can play it at a different speed. Hope you will enjoy it!
