Hi Tom,
do you use Karaf 2.3.3 ?
Actually, I reproduced your issue but it's not due to Cellar itself,
it's due to a change in Karaf 2.3.3 (a very bad change as it changes the
default behavior about ConfigAdmin storage for all config instead of one
as expected).
With Karaf 2.3.3, you have to change the following property in
etc/config.properties:
felix.fileinstall.enableConfigSave = true
Regards
JB

I have a question about cellar cluster:group features as follows:
1. install a new fresh copy of Karaf on a MacOS X machine
2. type the following commands:
features:addUrl
mvn:org.apache.karaf.cellar/apache-karaf-cellar/2.3.2/xml/features
features:install cellar
After that I pretend a new cluster group:
cluster:group-create test01
cluster:group-join test01
*karaf*@root> cluster:group-join test01
Group Members
* [test01 ] [192.168.28.163:5701* ]
* [default ] [192.168.28.163:5701* ]
*karaf*@root> cluster:group-list

* [test01 ] [192.168.28.163:5701* ]
* [default ] [192.168.28.163:5701* ]
*karaf*@root>
*karaf*@root>
*karaf*@root>

Then, I quit Karaf and restart it again.
Type the following command:
cluster:group-list
*karaf*@root> cluster:group-list
Group Members
* [default ] [192.168.28.163:5701* ]

The new group test01 is not shown again and find the following errors by
running "display" command:

Should cellar save all the group configuration I have created before?
Best Rgds,
