More information about your existing setup will be helpful here, like
the base operating system, lava-server and lava-dispatcher versions, etc.

As of lava-server and lava-dispatcher version 2018.1, lava-coordinator
should be installed only on the lava-server machine. It is not required
on the workers.
An installation of lava-server should automatically pull
lava-coordinator as a dependent package. If for some reason you want to
install it separately, then,
$ sudo apt install lava-coordinator
After installation of lava-coordinator on the same machine which runs
lava-server, check /etc/lava-coordinator/lava-coordinator.conf which
should look like the following:
<snip>
{
"port": 3079,
"blocksize": 4096,
"poll_delay": 3,
"coordinator_hostname": "localhost"
}
</snip>
The additional step is to copy that configuration file to each worker, changing the coordinator_hostname to the hostname of the master, so that each worker can find the coordinator. lava-coordinator should NOT be installed on the worker itself, just the configuration file.https://staging.validation.linaro.org/static/docs/v2/ simple-admin.html#checking- for-multinode-issues --
