I installed also intel microcode.

The only thing to do is a hard reset of the server...

Please help me to solve this big problem....

Thank you

 

[zeuxprox]

Do you think that by updating to Proxmox 6.1 the problem can be solved?

 

[budy]

Well, I think you should probably head over to the ZFS discussion list and try to get some help there.

 

[zeuxprox]

Where can I find "ZFS discussion"?

thank you
