### Fix DU3 cluster
1. Stop Nomad all servers
```bash=
systemctl stop nomad.service
```

2. Remove old nodes from the cluster
```bash=
nomad server force-leave nomad-du3-VM-01.DU3
nomad server force-leave nomad-du3-VM-02.DU3
nomad server force-leave nomad-du3-VM-03.DU3
```

3. Delete `/opt/nomad` 
```bash=
rm -rf /opt/nomad
```

3. Create `/opt/nomad` and grant rights to `nomad` user
```bash=
mkdir -p /opt/nomad
chown -R nomad:nomad /opt/nomad
```

4. Start nomad servers
```bash=
systemctl start nomad.service
```

5. Repeat on all cluster servers
