Hello,

Sorry if I allow myself to intervene, but before updating to version 8.0U2 you made sure that the context of your infrastructure was in some way supported / supportable, especially when things like vSAN are at play.

Regards,

Yes, I understand what you are saying, but it has happened and now I don't know how to solve this problem, please give me a solution

, Why are you using a consumer-grade device (Samsung 980 Pro) that is not on the vSAN HCL (for any vSAN usage type) as cache-tier device here?

 

This is beyond unsupported, you are potentially looking at data-loss here.

 

You should replace all unsupported devices here with devices that will actually be expected to work for the intended purpose here and restore any lost data from backup.

The problem has nothing to do with the hardware. In general, the power went out once and when we turned on the servers, this was the problem and it has not been solved until now.

It could have everything to do with the hardware, the 980 Pro doesn't have power loss protection, which means that if power goes out you can end up in a weird state. I think the best way forward now is to recover from a backup! Assuming you have a backup?
