Thank you. The problem turned out to be a bad GigE card in the new node.
The information both you and Bala provided was extremely helpful in
isolating and resolving the cause. I'm going to replace the card today
and I'm sure things will start to work correctly.
I did notice that the IP address range associated with the
/etc/dnsmasq.conf does have some issues.
1. The addresses associated with the pool must be the same as
those associated with eth0 or the dhcp IP address assignment to
a new node will cause the install to fail. That should be made
more clear. But, like Bala said the installer should not
expect to use eth0 (fixed in 3.1). With that fix in place I
would expect that the dhcp addresses could to be attached to
any interface and it would work as expected.
2. The range configured in the GUI doesn't match the range defined
in the conf file. Example, I have 10.0.0.102 - 10.0.0.110
configured in the GUI for the storage pool yet the line in the
dnsmasq.conf file reads:
dhcp-range=10.0.0.110,10.0.0.110,5
That may be by design, but given that configuration I can see
how having the last address in the pool being used would cause
the installer to fail. I guess you guys manage the DHCP pool
one address at a time, decrementing it as new nodes are
installed. You might consider using link-local addressing to
facilitate the install process making it transparent to the end
user.
It would be nice to include a utility in the installer to help identify
the Ethernet cards. Different kernels bring up the cards in different
orders so it's not always easy to know which card is which. A tool like
ethtool that allows you to see link is usually good enough to help you map
the cards to a interface name.
I would also suggest letting people know that there is a local caching DNS
server running which is why the first DNS server used in the install
process defaults to the local host IP address.
Thanks again,
Kevin
