PLEASE NOTE THAT ETH0 IS NOT STATICALLY ASSIGNED
----- the process -----
1. Node boots up
2. Node asks for IP via dhcp (eg 10.2.72.50) on mac=00:25:90:14:FA:30
3. Server assigns the lease IP AND creates 2 DDNS entries:
compute1 A 10.2.72.50
50 PTR compute1-s.poc.lzd.co.
4. Node starts netboot/xNBA process
5. Kickstart starts and asks for DHCP again.
6. Server assigns lease IP and
7. kickstart completes and starts the postscripts from the templates (
/opt/xcat/share/xcat/install/scripts/post.rh.common )
----- Here the problem starts -----
As my primarynic=eth1, the script tries to see if eth1 is up or not. If it
is not, it tries to bring it up.
However Line 41 of /opt/xcat/share/xcat/install/scripts/post.rh.common is
:
8. 41 dhclient eth0
This causes the eth0 interface to get a 2nd IP
9. Server assigns another IP to node (eg. 10.2.72.51) and updates DDNS:
compute1 A 10.2.72.51
51 PTR compute1-s.poc.lzd.co.
So on the server:
[root@xcatmn01 scripts]# host 10.2.72.50
Host 50.72.2.10.in-addr.arpa. not found: 3(NXDOMAIN)
[root@xcatmn01 scripts]# host 10.2.72.51
51.72.2.10.in-addr.arpa domain name pointer compute1.poc.lzd.co.
And on the node:
bash-4.1.2 # ip -4 a s eth0
2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq state UP qlen
1000
inet 10.2.72.50/24 brd 10.2.72.255 scope global eth0
inet 10.2.72.51/24 brd 10.2.72.255 scope global eth0
Now to connect to the server, the node address used is '10.2.72.50', but
the ip does not resolve to a name anymore.
So the script /install/postscripts/updateflag.awk keeps on trying to update
the server with it's status, and the server keeps ignoring the update,
leaving it in a stuck state.
I hope this clarifies the problem I face.
