Hello Gianluca,
Add/remove would probably be the simplest way to go.
The procedure would be:
- take host to maintenance
- remove host
- use vdsm-cient to change the ip of ovirtmgmt
- add the host again
Just changing the dns configuration sounds quite interesting.
I suppose the host certificates should be ok if the host was added by
hostname.
I've already done something similar in September; see here the full thread:
http://lists.ovirt.org/pipermail/users/2017-September/084411.html
In that case it was more complicated in the sense that vlan change was
involved for ovirtmgmt and I passed through a new cluster.
Now it is more simple, but while on September case the hosts were plain
CentOS hosts, now they are ovirt-node-ng, so my manual ifcfg files
manipulation doesn't fit.
If vdsm-client command is ok I presume it will be something of type:
# vdsm-client Host setupNetworks
vdsm-client: Command Host.setupNetworks with args {} failed:
(code=-32603, message=Attempt to call function: <bound method
Global.setupNetworks of <API.Global object at 0x2279f10>> with arguments:
() error: setupNetworks() takes exactly 4 arguments (1 given))
#
with some sort of json configuration, but it is not clear to me what to give
Can I do the change of ip from the host web cockpit mgmt interface? I
set/change the ip and then eventually reboot the server to see if it works?
