That would be terrific! Thanks for your efforts for making an awesome cifs

sure, you can offer an iscsi disk but recovering bare metal from iscsi
targets is not as easy as from a share ;-) and well, as I read in the

every now and then for a backup, or just live with a slower cifs protocol.

Interesting finding re. VHD support needing resiliency support in SMB 2.1.
Thanks for the KB article: https://support.microsoft.com/en-us/kb/2920193

We have resiliency support in NexentaStor 5.0 (shameless plug:)
https://nexenta.com/products/nexentastor
We should work on upstreaming that code soon.
