Win2016 ReFs repository server freeze during Back-up copy

[jja]

I see you have iscsi lun formatted with ReFS.
I found out on friday by an MVP, that this is unsupported, and you can experience total dataloss.

About midway down on this page you have the following:
(https://docs.microsoft.com/en-us/window ... s-overview)

"ReFS is supported with Storage Spaces, Storage Spaces Direct, and non-removable direct attached drives. ReFS is not supported with hardware virtualized storage such as SANs or RAID controllers in non-passthrough mode. USB drives are also not supported."
