Hi All,

I am getting following error,

```
CDB boot error: failed to load ./state/packages-in-use/1/discovery/load-dir/default.xml:3: unknown namespace: http://tail-f.com/packages/discovery in discovery
Daemon died status=10

```

Please suggest how to resolve this error?

Thanks,  
Neha

Hello,

please, can you check if required data model (`fxs` file) is loaded into the ConfD?

After starting ConfD, run command `confd --status` and search for  
`http://tail-f.com/packages/discovery` namespace in section `YANG data models`

Is datamodel (`fxs` file compiled form `yang`) on ConfD `loadPath` or `--addloadpath`?  
See `confd.conf` and `confd` sections in the ConfD User Guide or corresponding man pages.
