HI Rahul ,
Thanks for the reply.
I have seen the Disc space,it is good. Talking about the dependent services
metdata service and dhcp service are down. i can see these services are down by
using neutron agent-list command.

Check the logs in /var/log/neutron/dhcp-agent.log on the node where your
neutron services are running.
DNSMASQ would be run by neutron-dhcp-agent. Since dhcp-agent is failing, hence
you are not seeing any dnsmasq processes. Sometimes, such issues occur if disk
is full or other dependent services are not running.

Hi
We have OpenStack cloud setup on ICEHOUSE version.
We are facing an issue. Issue : VM is not getting the IP address released from
DHCP agent.DB entry of IP address for every instance is made. We have seen the
host file of DHCP service.(Host File : where MAC address and IP address
mappings are maintained). We have increased the timeout in neutron.conf and
started the debug process. During debug process, we have manually killed the
DNSMASQ service of DHCP agent using kill command. Now if we manually start the
neutron DHCP agent, the service is not getting started.
IS this due to killing the process of DNSMASQ service manually, if so how to
start DNSMASQ service explictly so neutron dhcp agent service can be started.
No logs available. If we start the DHCP service, it's not getting started.
neutron agent-list shows "xx" for DHCP agent.
Thanks in advance.
regards
SHanker
