XOA / NFS ISO - Unable to create on IPv6 NAS

PimAarts

Good afternoon,

I am unable to define an NFS ISO store on a NAS with an IPv6 address. However, I am able to create NFS SRs using the same IPv6 address.

Configuration:

XCP-ng fresh install of version 8.3 (with the latest patches applied)
Xen Orchestra - commit 6c258
NAS with IPv6 net

Walkthrough:
The 'Create a new SR' in Xen Orchestra works fine, I can put an IPv6 address in for the option 'server' and then I am able to select a path from a discovery of the nas options.
When I then press the 'Create' button, an error occurs.

sr.createIso
{
  "host": "8f38dc4c-e980-4064-bcf4-f66afc168c68",
  "nameLabel": "ISO Library",
  "nameDescription": "ISO Library on TrueNAS",
  "path": "2a10:3781:2ad:f5:92e2:baff:fe31:5b80:/mnt/Venus/ISO_Library",
  "type": "nfs"
}

      },

      "iso",
      true,
      {}
    ]
  },

Does it work for a regular SR or it's the same result regardless ISO & regular SR?

@PimAarts hi!
"path": "2a10:3781:2ad:f5:92e2:baff:fe31:5b80:/mnt/Venus/ISO_Library"

Should be "path": "[2a10:3781:2ad:f5:92e2:baff:fe31:5b80]:/mnt/Venus/ISO_Library" with brackets around the IPv6.

Hi Oliver,

Ik works fine with regular SRs.

I tried to fill in the IP address with brackets, but then the discovery of the NFS shares fails.

With regular SRs, it works fine without using brackets.
