Mark6 troubleshooting

General

In case you run into trouble with the Mark6 recorders first try to restart the cplane and dplane services.

You can download a service script (to /home/oper/bin) that reliably shuts down and restarts the services in the proper order. The script also displays the relevant logs files (named dplane-daemon.log, cplane-daemon.log) which can help you in debugging the issue.

as user oper:

m6service_restart

If the issue cannot be resolved by restarting the services try rebooting the mark6 machine.

Timezone

The configured timezone of the mark6 machine must be UTC otherwise starting of the scheduled recording will not work!

Check the timezone of the mark6 machine e.g. run:

date
> Tue Mar 17 08:12:54 UTC 2015

make sure that the timezone is UTC. If it is not run

dpkg-reconfigure tzdata
> Etc > UTC

Input_stream error

Before entering input streams, groups of diskmodules have to be in a closed state. When group is open you may see this problem when you commit the input_stream.

After committing the input_stream, the command returns a disk module status.  You should restart cplane and be sure the disks are in a closed state.  The expected input_stream=commit response should be:

>> input_stream=add:FILA10G-L:vdif:8224:50:42:eth3:172.16.3.1:0:12
<<  !input_stream=0:0;

<<  !input_stream=0:0;
>> input_stream=commit
<<  !input_stream=0:0;
