Re: [Rocks-Discuss] IP change on frontend

[H P]

Hi

We have changed IP, subnet and netmask with following commands...

rocks set network netmask public <new netmask>
rocks set network subnet public <new subnet>
rocks set host interface ip frontend eth1 <new ip address>

These commands changed entries in database for related tables. However
it didn't change values in table global_attributes which has
values like Kickstart_Public[adress/network/broadcast/gateway]. When
we searched on web for commands which will change

this attrs in database , we found few commands but it looks like those
commands doesn't work with Rocks 5.4.

command: rocks set var Kickstart PublicAddress <IP>

Since we know where these values are in database we can try changing values
in 'global_attributes' table. But I guess that in not the ideal way of doing
as some other conf file or table may have same info stored.

Now there are 3 main issues.

[1] How to changes entries*[**
Kickstart_Public[adress/network/broadcast/gateway]** *in database with rocks
command (or by other recommended alternative way)

[2] How to change gateway in database?

[3] How to push related configuration files to compute nodes?

Regards
HP

also an attribute. Try rocks list attr

Reinstall is guaranteed to work (assuming all entries have changed in the
DB).
A
rocks sync host network
should get the appropriate changes (but hat is not guaranteed)

after
rocks sync network
rocks sync config
re-install compute nodes

Hi Philip and Hung,

We have tried your suggestions.

rocks set attr Kickstart_Public* < ip | network | dns | broadcast | gateway
> has changed values in database 'global_attributes' table.

So looks like everything is fixed on frontend except main gateway.
Kickstart_PrivateGateway and Kickstart_PublicGateway are changed but not
able to see changes.

'rocks report host network' still shows old gateway. We also checked for
entries in /etc/sysconfig/network and there is no entry for GATEWAY in it.

We tried to set the gateway with UI in frontend. However whenever we restart
the network service it goes blank and needs to be set again.

[root@rash sysconfig]# rocks report host network
rash: <file name="/etc/sysconfig/network">
rash: NETWORKING=yes
rash: HOSTNAME=rash.local.com
rash: GATEWAY=192.168.20.1
rash: </file>
compute-0-0: <file name="/etc/sysconfig/network">
compute-0-0: NETWORKING=yes
compute-0-0: HOSTNAME=compute-0-0.local
compute-0-0: GATEWAY=10.1.1.1
compute-0-0: </file>
compute-0-1: <file name="/etc/sysconfig/network">
compute-0-1: NETWORKING=yes
compute-0-1: HOSTNAME=compute-0-1.local
compute-0-1: GATEWAY=10.1.1.1
compute-0-1: </file>
compute-0-2: <file name="/etc/sysconfig/network">
compute-0-2: NETWORKING=yes
compute-0-2: HOSTNAME=compute-0-2.local
compute-0-2: GATEWAY=10.1.1.1
compute-0-2: </file>
[root@rash sysconfig]#

We have not tried re-building compute nodes as we want to make sure that
front-end is perfect before doing it.

Regards
HP

may be just add GATEWAY

[Thomas Indelli]

I'm wondering if perhaps the GATEWAY field is being cleared because the one you specified is invalid for the network. When you specified the Kickstart_PublicGateway attribute, did you put the gateway for your public interface (external IP) which should differ from your Kickstart_PrivateGateway entry? The cluster I was doing this on before has entered production now, so I don't want to test things out over SSH while an hour away from the office at 1 AM, but I would make sure you have the appropriate values set for Kickstart_Public* which should differ from Kickstart_Private*. You can check by running /opt/rocks/bin/mysql -uroot -p cluster and doing "SELECT * from global_attributes" to see all the attributes.
