Description

Interop testing is broken after landing "LU-11025 dne: introduce new directory hash type: "crush"".

It makes impossible to start new client that include 0a1cf8da8 with servers that don't:

cslmo1103: error: set_param: param_path 'lod/*/mdt_hash': No such file or directory
pdsh@c-lmo004: cslmo1103: ssh exited with exit code 2 

I guess following code should check that MDTs support mdt_hash param:

init_param_vars () {
...
        do_nodes $(comma_list $(mdts_nodes)) \
                "$LCTL set_param lod.*.mdt_hash=crush"
        return 0
}
