Replication has stopped after ugprade

[Sebastian Roth]

@moses As far as I can tell those messages in the apache error logs are not related to the replication issue. But we should still get that fixed!! I remember talking to Tom because I saw the exact same errors on my virtual machine setup here - this is kind of special as I am using a tap network device and FOG wasn’t happy with that. We fixed it but this might have broken it for others. Can you please post the output of ip addr on your FOG server.

@Tom-Elliott Should we better use /sys/class/net/*/operstate instead of calling ip/ifconfig??

About the replication. Tom and Wayne have been working on this lately but I don’t think it’s the same issue. Please check if the services/daemons on your FOG server are all running: ps ax | grep FOG (maybe they fail on startup/restart?!)

[moses]

@Sebastian-Roth This is all I got as output from ps:

 1341 ?        S      0:00 /usr/bin/php -q /opt/fog/service/FOGTaskScheduler/FO TaskScheduler
 1364 ?        S      0:00 /usr/bin/php -q /opt/fog/service/FOGPingHosts/FOGPingHosts
 9595 ?        Z      0:00 [FOGPingHosts] <defunct>

10088 pts/1    S+     0:00 grep --color=auto FOG

So perhaps multiple services are failing on start? Is there any way to find logs that would indicate the why?

[moses]

@Sebastian-Roth Here’s the output of ip addr:

@Sebastian-Roth After updating this morning, the services now appear to be running (they are not running after a restart), but replication still isn’t actually taking place, nor has the log for the Image Replicator changed from my original post.

[Tom Elliott]

@moses can you check the storage nodes all have their proper network interface set correctly? This is why the errors and would also cause issues with the services as they’re waiting for the interface to become available.

[moses]

@Tom-Elliott I checked the setting in Storage Mgmt > Storage Nodes and they all match what is shown using ifconfig on the nodes thru ssh.

[Tom Elliott]

@moses if you manual stop and start the services do things work?

[moses]

@Tom-Elliott Nope, though the behavior there is kind of odd:

If I restart, it says “failed”.

If I stop, then start, it says “OK” for both, but nothing in the logs, and an image that is supposed to be replicating is not.

[Tom Elliott]

@moses So you’re running a variant of Ubuntu, Just guessing?

[moses]

@Tom-Elliott ubuntu 14.04

[Tom Elliott]

@moses Can you run:

sudo service vsftpd stop
sudo service FOGImageReplicator stop
sudo service FOGSnapinReplicator stop
sudo service FOGPingHosts stop
sudo service FOGMulticastManager stop
sudo service FOGScheduler stop
sleep 5
sudo service vsftpd start
sudo service FOGImageReplicator start
sudo service FOGSnapinReplicator start
sudo service FOGPingHosts start
sudo service FOGMulticastManager start
sudo service FOGScheduler start

[moses]

@Tom-Elliott okay, did that:

administrator@SVR-HQ-IMAGING:~$ sudo service vsftpd stop
vsftpd stop/waiting
administrator@SVR-HQ-IMAGING:~$ sudo service FOGImageReplicator stop

administrator@SVR-HQ-IMAGING:~$ sudo service FOGScheduler start

Still no change, however (no replication or log changes)

[Wayne Workman]

I just updated to the latest, then deleted all images on my slave node, and quickly rebooted both master and slave machines… we’ll see how it goes.

[moses]

@Wayne-Workman See anything on that slave? Trying to determine if this is just an issue somewhere on the master I’m running.

[Wayne Workman]

@moses It replicated every image back perfectly. There’s something with your setup. Keep in mind it could still be FOG-related though, such as a credentials issue, it could be firewall related, or SELinux related. You might even be out of space on the storage node?? There are many possibilities.

I know you have said you’ve verified the FTP credentials, but let’s make doubly sure? There are instructions here for testing it: https://wiki.fogproject.org/wiki/index.php?title=Troubleshoot_FTP

Basically you should ssh into your main and try to open an FTP connection to the other nodes using the user/pass they have set in their respective listing under storage management.

Then the opposite, from the nodes, try to open an FTP connection to the main using the main’s credentials that are set in it’s respective Storage Management listing.

[Sebastian Roth]

@moses Did you find out what’s going wrong with the services? Any errors in the apache log when you try starting the service?

We’ve fixed the bandwidth.php issue. Can you please update to the latest version to see if those errors stop and the bandwidth monitor on the dashboard works for you.

[moses]

Unfortunately, even with some hands-on help, I wasn’t able to determine what the cause was. At this point my best bet was that it’s related to Linux. Even upgrading to a newer distro didn’t help. I’m currently in the process of moving my configuration over to CentOS, once I back up my images.

[Sebastian Roth]

@moses Are the services actually running after you started them by hand? ps ax | grep FOG

[Junkhacker]

if you run top, how much of your cpu do these services utilize?

[moses]

After moving my installation over to CentOS, the Image Replication service now starts. Hooray!

But alas, I run into another issue. See the last line of the fogreplicator.log:

This error only appears if I add an image to one specific storage group. Should I maybe delete the storage group or the node there and re-create them?
