So far unconfirmed rumours claim that ESXi 6.7 u 2 comes with a voma module called "advcfg".
According to the rumours that module can actually really clean up stale locks in a VMFS 6 heartbeat section.
Has anybody seen that module in action ? ... and is willing to talk about it ?
I am aware that this may be regarded as a delicate and intimate question so feel free to contact me via PMs or email if you do not want to talk about this in public.
