I would like to know some details regarding CTK and the multi-writer flag not being supported.
If my disk A,B, C are used as multi-writer and shared, can I still enable ctk on disks D,E, F ( given that i won't enable/add ctkEnabled = "TRUE" parameter on configuration file )
according to this https://kb.vmware.com/s/article/2110452
seems you need to disable the CBT for all the disks of the VM is not explicitly said if you can do only for the multi-writer disks. Seems a security measure that is by default set on false with esxi 7.0.
I remember that we had a similar issue moving from 6.7 to 7.0 and the only solution was to apply this KB.
