Hi,
We have 4 NIC controllers on ceph servers. Each server have installed
few osd's and one monitor. How should we setup networking on this hosts
with division on frontend network (10.20.8.0/22) and backend network
(10.20.4.0/22)?
At this time we are using this configuration of network:
auto em1
iface em1 inet static
address 10.20.8.30
netmask 255.255.252.0
gateway 10.20.8.1
dns-nameservers 8.8.8.8 8.8.4.4
auto em2
iface em2 inet static
address 10.20.4.30
netmask 255.255.252.0
dns-nameservers 8.8.8.8 8.8.4.4
auto p4p1
iface p4p1 inet static
address 10.20.4.31
netmask 255.255.252.0
dns-nameservers 8.8.8.8 8.8.4.4
auto p4p2
iface p4p2 inet static
address 10.20.8.31
netmask 255.255.252.0
dns-nameservers 8.8.8.8 8.8.4.4
On the ceph.conf:
...
[osd.16]
cluster addr = 10.20.4.30
public addr = 10.20.8.30
[osd.17]
cluster addr = 10.20.4.30
public addr = 10.20.8.30
[osd.18]
cluster addr = 10.20.4.30
public addr = 10.20.8.30
[osd.19]
cluster addr = 10.20.4.31
public addr = 10.20.8.31
[osd.20]
cluster addr = 10.20.4.31
public addr = 10.20.8.31
[osd.21]
cluster addr = 10.20.4.31
public addr = 10.20.8.31
...
[mon.ceph30]
host = ceph30
mon addr = 10.20.8.30:6789
