Harmonic MediaGrid Release 4.1

Checking Log Files for Errors

dhcpd status example 2:

[root@CDL1 dhcp]# pgrep dhcpd

3027

As mentioned before, the DHCP servers in the Harmonic MediaGrid are configured in a peer 
relationship. Both servers have to be up or one must timeout and wait for the other to come 
online. In the output of /var/log/messages below, the communication between ContentDirector1 
(shown as CLD1) and ContentDirector2 (shown as CLD2) has been interrupted. In the following 
example, DHCP has been stopped on ContentDirector1, and the output messages are from 
ContentDirector2. Note the “communications-interrupted” message:

Feb  9 13:30:57 CDL2 dhcpd: failover peer Public B: I move from normal 

to communications-interrupted

Feb  9 13:30:57 CDL2 dhcpd: peer Public A: disconnected

Feb  9 13:30:57 CDL2 dhcpd: failover peer Public A: I move from normal 

to communications-interrupted

Also shown in the output below is the services being restarted on ContentDirector1. Shortly after 
restarting services on ContentDirector1, ContentDirector2 logs a message to /var/log/message 
that communications have moved from interrupted to normal:

Feb  9 13:31:38 CDL2 dhcpd: failover peer Public B: I move from 

communications-interrupted to normal

Checking Log Files for Errors

Looking for Startup Errors in the mdscore Log File

The number one cause of services not starting on ContentDirectors is that the times are not 
synchronized across ContentDirectors. Times must be synchronized so that journaling and sync 
files across the ContentDirectors have the same timestamps. The times must be within about 4/
10ths (0.4sec) of a second or less for the services to run. Below is a portion of the mdscore log 
file that shows the error message for a ContentDirector, which does not have its time 
synchronized with another running ContentDirector.
