Openfiler network services problem investigation

At some point my lab Openfiler was assigned static ip address and the iSCSI target stopped to function; also it was not reachable by the web interface at tcp port id 446 anymore. Several reboots did not help to solve the problem.

What happened? The network interface configuration was changed. One of the eth config files was changed from DHCP to a static ip address.

vi /etc/sysconfig/network

[root@net-nas-01 sysconfig]# cat network
NETWORKING=yes
HOSTNAME=net-nas-01.networknet.nl
GATEWAY=192.168.100.254

vi /etc/sysconfig/network-scripts/ifcfg-eth0

[root@net-nas-01 network-scripts]# cat /etc/sysconfig/network-scripts/ifcfg-eth0
DEVICE=eth0
IPADDR=192.168.100.12
BOOTPROTO=static
NETMASK=255.255.255.0
NETWORK=192.168.100.0
GATEWAY=192.168.100.254
BROADCAST=192.168.100.255
ONBOOT=yes

Openfiler service failed if you checked the services (# service –status-all). The problem is Openfiler service checks the FQDN in the hosts file located in the etc directory.

[root@net-nas-01 ~]# service openfiler –full-restart
Stopping openfiler:                                        [FAILED]
Starting openfiler:                                        [FAILED]
[root@net-nas-01 ~]# service openfiler -configtest
Usage: openfiler {start|stop|restart|condrestart|reload|status|fullstatus|graceful|help|configtest}
[root@net-nas-01 ~]# service openfiler configtest
httpd: Could not determine the server’s fully qualified domain name, using 127.0.0.1 for ServerName
Syntax OK
[root@net-nas-01 ~]# cd /etc
[root@net-nas-01 etc]# cat hosts
# Do not remove the following line, or various programs
# that require network functionality will fail.
127.0.0.1               localhost.localdomain localhost

Go and modify the hosts file. To modify the hosts file run this command –> vi /etc/hosts and make sure the FQDN names for 127.0.0.1 and the static ip address are set correct.

[root@net-nas-01 etc]# service openfiler –full-restart
Stopping openfiler:                                        [FAILED]
Starting openfiler:                                        [  OK  ]
[root@net-nas-01 etc]# cat hosts
# Do not remove the following line, or various programs
# that require network functionality will fail.
127.0.0.1                 net-nas-01.networknet.nl
192.168.100.12            net-nas-01.networknet.nl
[root@net-nas-01 etc]#
