Storage Nodes & Disk Info Pie Chart

[Neil Underwood]

OK. I believe I have enough info now to straighten this out. It definitely appears that I need to add some GRANTS. Thank you for pointing me in the right direction. SQL is very foreign to me. I will return once I have fixed this to share my final solution. Thanks guys.

Whoa boy did I muck this up. Somehow I managed to get myself locked out of the web interface, only to be met with the schema updater and a failure to update anything from there. Not sure exactly what I did to piss it off, but I’m back to where I started now. I dumped my current mysql database, completely removed FOG ( except for images ), reinstalled FOG, then re-imported the database and I’m back up.

I can most definitely log in to the mysql database from the storage nodes now, but I’m still not getting any disk info. At this point I think I’m OK with that. That was 3 hours of panic that I do not wish to encounter again. Of course this all had to happen on the day we received a dozen new PC’s, just to make it more stressful.

So to recap:

FTP access - check
MySQL access - check
Disk Info - Nope

Time for some sleep.

@Neil-Underwood The fix is very simple. All you really need to do is edit the my.cnf file in /etc/mysql/my.cnf. And comment the bind-address line with the # symbol. Once commented and saved, restart the mysql service. That should be it.

For me, it’s normally two part… Maybe I was doing it wrong the whole time?

GRANT ALL PRIVILEGES ON . TO ‘fog’@‘%’ IDENTIFIED BY ‘PassHere’ WITH GRANT OPTION;

and inside my.cnf, I set
bind-address = *

All you need to do is comment the bind-address. The * does the exact same thing as the comment will do. You also don’t need to set a wildcard user as one already exists (AKA fogstorage found in FOG Configuration Page->FOG Settings)

FOG Settings)

Oh that’s what that’s for… nice.

I’ve had bind-address commented out from the inception of this issue. If I uncomment it I get a whole different set of problems.

The problem now is with tftp it seems. My clients are getting a file not found error when attempting to PXE boot. I thought I straightened out all the usernames/passwords.

Config.class.php TFTP_FTP_USERNAME/PASSWORD and STORAGE__FTP_USERNAME/PASSWORD both match the username/pw in the TFTP Server settings on the web interface. The username, ‘fog’, has the same unix password as what is in the aformentioned settings and has full access to /tftp.

The only conflict I now see is the Fog Storage Nodes credentials. I have one set in the web interface fr user “fogstorage”, and in Config.class.php I have this:

                define('DATABASE_TYPE',         'mysql');       // mysql or oracle
                define('DATABASE_HOST',         'localhost');
                define('DATABASE_NAME',         'fog');
                define('DATABASE_USERNAME',             'root');
                define('DATABASE_PASSWORD',             'xxxxxx');
        }

Should these settings match? I’m confused because updating one doesn’t seems to change the other and I’m unclear on which settings correlate to one another from the config files to the web interface.

Let us know if you need help.

I got it working! I’m really uncertain exactly what it was that finally did it though

Basically I made the password for user ‘fog’ the same on all 3 machines. I then made sure this user/pass combo was the same for the mysql ‘fog’ user, as well as the tftp & ftp storage user/pass. So in short everything has the same login credentials across the board.

I also created specific grants for each remote user, e.g.

GRANT ALL PRIVILEGES ON *.* TO 'fog'@'192.168.xxx.200' IDENTIFIED BY 'xxxxxxxx' WITH GRANT OPTION;

for each remote ip address.

Thanks to everyone for your assistance. Special thanks to Tom for taking the time to have a private chat session with me to help me get this figured out. You guys are awesome.

PS - Not sure how to mark solved on this forum…

OK so I’m left with a lingering issue now. I’m trying to deploy an image to make sure everything is working, but the image is only being pushed out from one of the remote nodes to a local machine over the MPLS, giving me a horrible transfer rate of ~ 80MB/min. Why would it not deploy the image from the local server? I’ve witnessed this system deploy an image in under 6.5 minutes. What logs should I be checking to figure this out?

[Wayne Workman]

Are you using the Location Plugin ? If so, double-check those settings. It’s really easy to orphan settings in there when you change things around. If you’re using the location plugin, maybe even re-configure it.

[Neil Underwood]

No, I’m not using the location plugin. Should I be? I had the impression that it was kind of abandoned/for older versions of FOG so I never actually looked into it.

[Neil Underwood]

OK well that did it. I installed the location plugin and now everything is back up to speed. I guess it just needed a little direction and I just got lucky on that first image I deployed to test the remote storage node. Thanks again.

It’s not abandoned at all. It’s in-fact the most important plugin of all.

Let’s figure it out. Where are your storage nodes? Are they separated by WAN links? Are they on different networks (different broadcast domains) ?

[Wayne Workman]

I sit on pages reading… you post fast, didn’t see your last post.

Glad you got it working.
