Request support for exporting/importing xCAT groups

[whowutwut]

It seems like this function is missing. We do have some differences between groups that display via lsdef and groups that show on nodegroup dump... seems like grouptype=static is required..

[root@boston01 ~]# tabdump nodegroup
#groupname,grouptype,members,membergroups,wherevals,comments,disable
"mid_switch","static",,,,,
"cn_regex_p8le","static",,,,,
"edge_switch","static",,,,,
[root@boston01 ~]# lsdef -t group
all  (group)
boston  (group)
cn_regex_p8le  (group)
edge_switch  (group)
firestone  (group)
garrison  (group)
mid_switch  (group)
p8le  (group)
switch  (group)

But exporting does not work...

[root@boston01 ~]# xcat-inventory export -t group
Error: Invalid object type: "group"
[root@boston01 ~]# xcat-inventory export -t nodegroup
Error: Invalid object type: "nodegroup"
[root@boston01 ~]#

hi, @whowutwut , currently, the node and group in def commands are all node in xcat-inventory since most of the attributes of them are the same, there are differentiated by the "obj_type": "group", in the xcat-inventory exported inventory file.

[root@c910f03c05k21 xcat_clusters]# xcat-inventory export -t node -o service
{
    "node": {
        "service": {
            "device_type": "server",
            "engines": {
                "netboot_engine": {

                    }
                }
            },
            "obj_type": "group",
            "role": "compute"
        }
    },
    "schema_version": "1.0"
}

will take a look how to separate them with different type in xcat-inventory -t

@immarvin Thank for that... interesting..

I'm trying to figure out how one would be able to add/remove machines from the group easily by modifying the files in the source control.. If we had static groups, would we be able to just add nodes to it? Or we would have to create these obj_info for each node object and add them into the group?

This is not a requirement but I'm just trying to see how we could easily manage a cluster directly from source control instead of xCAT commands.
