We have an 'old-style' cluster, seperated LAN/cluster network. We would like to move over to the 'new-style'.

Is it as easy as: define the NICs in a 2x10G LACP bond0, and add both NICs to the bond0 config, and add configure like:

auto bond0
iface bond0 inet static
    address 192.168.0.5
    netmask 255.255.255.0

and add our cluster IP as a second IP, like

auto bond0:1
iface bond0:1 inet static
    address 192.168.10.160
    netmask 255.255.255.0

On all nodes, reboot, and everything will work?

Or are there ceph specifics to consider?

Thanks,
MJ
