Re: [ovirt-users] Add more hosts

Trying to set the maintenance gives me: [root@vm01 ~]# hosted-engine --set-maintenance --mode=global /usr/lib/python2.7/site-packages/ovirt_hosted_engine_ha/lib/storage_backends.py:15: DeprecationWarning: vdscli uses xmlrpc. since ovirt 3.6 xmlrpc is deprecated, please use vdsm.jsonrpcvdscli import vdsm.vdscli it's not vey clear if it worked and it's just a warning or since it's deprecated it didn't work at all
