perfSONAR User Q&A and Other Discussion

Hi Casey,

Is the directory /etc/maddash/maddash-server and it’s contents owned and readable by the maddash user? Not sure why it would have changed but the following should make it readable if its not:

chown -R maddash:maddash  /etc/maddash

chmod 755  /etc/maddash/maddash-server

chmod 644 /etc/maddash/maddash-server/maddash.yaml

Thanks,

Andy

Group,

     After waiting patiently for 4.0.0.1 I upgraded one of my 3.5.1 hosts today and promptly broke it (yay me!).  Fortunately most everything appears to be working except for Maddash. 

     The host is my Mesh Config creator/distributor, my Central MA for the Mesh, a full toolkit install and lives on a VM.  I upgraded it directly from 3.5.1 via yum and it seemed to go fairly well.  

     If I go to the toolkit page and log in, I still see the test results for the full mesh and the results are currently updating, so I'm faaairly confident that the previous problems reported (postgres, etc) aren't at fault.  But the Maddash server stops about 15 seconds after starting.  

[root@ps-dashboard crussell]# service maddash-server restart

Stopping maddash-server:                                   [FAILED]

Starting maddash-server:                                   [  OK  ]

[root@ps-dashboard crussell]# service maddash-server status

maddash-server (pid  8173) is running...

[root@ps-dashboard crussell]# service maddash-server status

maddash-server (pid  8173) is running...

[root@ps-dashboard crussell]# service maddash-server status

maddash-server dead but pid file exists

[root@ps-dashboard crussell]# 

The only hint I've found thus far in the logs comes from /var/log/maddash/maddash-server.out  (here is the end of the output after a restart of the service.)

It looks like a permissions error, but I can't tell what (specifically) is failing.

Thoughts?  

P.S. and thank you in advance
