Hi,
the last days I discovered something in many forums and blog posts around the world which makes me really worried. It seems that with ESXi 6.0 and VADP (especially CBT) there might be a major and very disastrous bug. VMware covers it here VMware KB: Backing up a virtual machine with Change Block Tracking (CBT) enabled fails after upgradi...
Problem is, they are only talking about a CBT issue which produces some errors. They are *not* talking about potential data corruption. And I am talking about the running production VM from where the snapshot was taken.
Now - when looking at posts like this here: ESXi 6.0 CBT issue | view topic (there are many more on the net) I am wondering if somehow the snapshot commit operation in ESXi 6 is producing data corruption. Maybe it is only the VADP-triggered snapshot commit and (again) maybe there is more - some posts could even suggest that a partially snapshot rollback is accidentally triggered instead of a snapshot commit.
So - from my point of view - these problems are extremely serious and maybe disastrous. If VMware is aware of anything like this I would highly recommend to set a global letter to all customers, at the least to update the knowledge base article.
Is there any news around here in the forum?
Best regards,
Joerg
