FOGImagereplicator not working

Wayne Workman

@Neil-Underwood The true test is to connect via CLI, as the tests show in that article, using the credentials you have in storage management.

Also, this is a thread about replication, so you have two or mode nodes. You’re trying to connect to the problematic one correct?

Neil Underwood

Well, I have 9 nodes actually, plus the master storage node. None of them are replicating at all. They all give me the same results.

Not sure if it’s related or worth mentioning, but at the same time this started happening, I started having issues with bzImage reaching 99% and then just sitting there when trying to run a task.

Neil Underwood

FTP testing checks out with no issues. I can put, get and delete just fine.

Wayne Workman

@Neil-Underwood I think this is a problem with the central server. Not sure exactly yet, we need some more information. What OS is the main server? Have you reviewed firewall and SELinux (if applicable)?

For troubleshooting, please just turn off all firewalls on the nodes and main server.

Also, inside of Web Interface -> FOG Configuration -> Log Viewer -> Apache Error Logs What do you see in there, if anything? If that’s blank, get them manually from the OS. Depending on the OS, they are in different spots. RHEL and variants are /var/log/httpd/error_log and Debian variants are /var/log/apache2/error_log

And, you can find replication logs on the main server here: /opt/fog/log

I’m on Ubuntu 14.04. No firewall, no SElinux. In the web interface I get “Unable to open file for reading” for all apache logs. When viewing them manually I get:

The fogreplicator.log file is completely empty. I deleted it and recreated it a few weeks ago during my troubleshooting. Prior to that it contained entries up to March and then it stopped.

@Neil-Underwood Please give this a shot:

sudo -i
service FOGImageReplicator stop
service FOGSnapinReplicator stop
service FOGMulticastManager stop
service FOGPingHosts stop
service FOGScheduler stop
sleep 10
service FOGImageReplicator starts
service FOGSnapinReplicator start
service FOGMulticastManager start
service FOGPingHosts start
service FOGScheduler start

Ubuntu is realy strange. If there’s a pid file, but the process died, it will fail to allow the next item to startup (at least not properly). Restart appears to make it not remove the lock, at least in my experiences.

Also, if you’re running from a GUI 14.04, make sure when you go into sudo on the terminal, you first jump up to root with sudo -i. The normal terminal window (even if you are logged in to the Ubuntu system as root) will not source all the paths as needed. This is what I’ve seen, of course I have been wrong.

I tried this with no success. Did it twice to make sure. The first time I stopped FOGImageReplicator and FOGSnapinReplicator they both complained about no existing process, but agreed to close anyway. The second time I did it they did not complain but the outcome was the same.

Looking more closely at all my log files, I see that only servicemaster.log is current. Everything else hasn’t changed since March/April. Looking at multicast.log I see something that looks very wrong:

Not sure how this box lost master node status. It’s never been changed. That is a bit worrisome though. I feel like there are multiple issues with this setup.

Here’s another side-effect of whatever is ailing my server here:
0_1466518209461_Screenshot from 2016-06-21 07:08:22.png
All of the nodes now show (#!db) instead of whatever it’s supposed to show (version number I think?)
Could it be a corrupt database that’s causing all of this?

You know, that prompted me to look at class.config.php and I think the DATABASE_HOST value is wrong, but I really don’t know. Can you verify this is correct? Should the “p:” be in there proceeding the IP address?

define('DATABASE_HOST','p:127.0.0.1');

I tried changing it and removing the “p:” and nothing seemed to change (after restarting php, mysql & apache just to be sure)

Wayne Workman

@Neil-Underwood so, for the main server that hosts the DB, that is correct. For all nodes, it is wrong.

Neil Underwood

OK, so now I’m seeing that I can’t connect to the master storage node DB from the remote storage nodes. I know as much about SQL commands and permissions as my left shoe. How do I fix this? And how in the heck did it break in the first place?

Probably the server is only allowing local connections. There’s stuff about that in here:

“Enable Remote MySQL Access”

I must have overlooked the part about remote access because I visited this page earlier this morning. I fixed the remote permissions and now everything is able to see the DB. Thanks for that. I did do an OS upgrade that probably changed mysql versions. I’m betting that’s what screwed it up.

The mystery of where my log info is going still remains, however.

Also, on the dashboard the replicator appears to be working, based on the graph. But running jnettop from the master storage node doesn’t show any replication activity. If I can get my logs working again I’m certain I can figure out what the problem is.

Wayne Workman

@Neil-Underwood sometimes it takes a hot second for replication to kick in, even if the log says it’s going. Just be patient. Tomorrow morning you’ll be able to tell if everything is right or not.

Also, the logs might be fixed by re-running the installer on all the nodes, since it can now actually communicate with the DB.

Neil Underwood

OK so I’m updated to 8215 now and everything seems to be able to see each other. It looks like the main server is pushing our the smartinstaller.exe to all the clients and that’s the activity I’ve been seeing on the graph. Hard to catch that using jnettop at first.

Thanks for all the assistance with this. I’ll open a separate thread for the log issue and another for the bzImage problem.

One more quick question though. What are these values used for?

startrange='192.168.19.10'
endrange='192.168.19.254'

@Neil-Underwood DHCP Server if FOG is to be the dhcp server.

It defines the start and end range of DHCP.

Got it. So this does not apply to my setup then. Must have been defined a long time ago when I was playing with that. Thanks!
