Hi Ashraf,

Did you set up password-less ssh? Can you run 'hostname' command on any node?
[g201002860@hpc081 ~]$ssh hpc082 hostname

This is the first requirement.

Regards!

Although coming after two years, but for those, who might end up here, after searching online. 

'Alarm clock' error might be displayed if a mpd process crashes badly.  Then execute

mpdcleanup

This command cleans up the crashed files and allows mpd to run again. This might need to be done on each node. Instead one could also use

mpdcleanup -a

for cleaning up all the nodes at once.

regards,

Adhip
