Enable NBD Backups for a network

lawrencesystems

I am running xo-server 5.109.0 & xo-web 5.111.0 and I have enabled NBD from the UI and verified that the parameter is showing on that network. This is the network on which XO is talking to XCP-NG .

                 purpose (SRW): nbd

I know I also have to be using the multiple data blocks on for the backup repository but I do have a few other questions:

Because the NBD option is now in the XO UI do I still need to edit the XO config.toml file & restart XO to enable or is that automatic?
Are there any firewall changes on the XCP-NG host or does this work over 443?
Does it matter if XO is running in another pool?
In the Xen Orchestra 5.76 Blog Post it was mentioned the "Lock" in the new "NBD" row which I see but is there some change I need to make?

Adding @florent in the loop (I'm at FOSDEM right now, so not really available)

hi @lawrencesystems

You still need to enable it in config fr now. I hope we 'll be able to improve the ui to enable it on a per backup setting later

The nbd protocol use the 10809 port in TCP by default. XO only read from this port f the host.

The Nbd setting is used for the whole xo, regardeless of the pool

The lock have been replaced by a select, which is more self explanatory . I think the main control pint is to check if there is multiple NBD network for a VM, XO use the first one returned by the Xapi, and it may be , for example, a managemet network as opposed to a backup / high speed one
