Does FOG work with iSCSI?

[Wayne Workman]

@ManofValor Yes, everything in fog must be defined in one place or another in the DB, which means creating it in the Web Interface. You must create a storage node definition for the NAS.

[ManofValor]

@Wayne-Workman Is it possible to edit my existing node or better to just create a new one?

@ManofValor said in Does FOG work with iSCSI?:

I don’t know how you have it setup. Anything you delete in the web gui, you can remake. You’re using a iSCSI which is not locally on your fog server. This means you’d create a new node. If that’s all you will be using, this can be your only node.

It’s pretty simple. You create a new node, type in the image path, FTP images path, the IP address, and FTP credentials, set a storage group, enable it… We have probably over 100 threads about this in the forums, there are articles on it in the wiki too.

You do not have to wait to be told what to do, please feel free to try different things very, very rapidly. You can’t break anything that can’t be fixed too.

[ManofValor]

So I went in to FOG management and created a new storage node for my NAS.

Once I did that I ran yum update -y, git pull, rebooted, and then ran ./installfog.sh. At the end of the install I got this:

 ########################################################################################
   FOG has adjusted to using a login system to protect what can/cannot be downloaded
   We have detected that you don't have credentials defined to perform the backup
   If you would like the database to be backed up during install please define
   in your /opt/fog/.fogsettings file

   fogguiuser='usernameOfFOGGUI'
   fogguipass='passwordOfFOGGUIUser'

   You can also re-run this installer as:

   fogguiuser='usernameOfFOGGUI' fogguipass='passwordOfFOGGUIUser' ./installfog.sh -y
 ########################################################################################


 * You still need to install/update your database schema.
 * This can be done by opening a web browser and going to:

   http://10.10.1.40/fog/management

 * Press [Enter] key when database is updated/installed.

Also When I click on the FOG Configuration button (the little wrench) in FOG management, I get this:

I also created a NAS directory (/opt/fog/images/NAS/) for the new storage node.
What is going on?
Thanks.

[Wayne Workman]

@ManofValor The interface you’ve set is not correct. On the tera-station, get into CLI and issue ip addr show and read the right interface with that IP. More details on the interface are here: https://wiki.fogproject.org/wiki/index.php?title=Troubleshoot_FTP

The bad request when going to FOG Configuration is likely a php syntax error in the code base, which I am sure will be fixed soon - but we need the apache errors.

In Fedora/CentOS/RHEL they are here: /var/log/httpd/error_log and in debian/ubuntu I think they are here: /var/log/apache2/error_log The error should generate right after trying to access that page. Please copy/paste the relevant errors. They will have timestamps to help. Going to ping @Tom-Elliott about this one.

The message from the installer is something added last week, a security measure to further protect the DB. If you do what the instructions say, you won’t see it anymore and the DB will backup automatically when you run the installer from that point onward.

And I don’t think it was necessary to make a /opt/fog/images/NAS on the server. Also, I’m wondering about your image path you have set. You can use that above FTP article to test FTP to the NAS and verify that path to be sure it’s correct. Also, if that’s what you’re going with, make sure you have /images/NAS/.mntcheck and /images/NAS/dev/.mntcheck present. You can use the touch command to make these, for example touch /images/NAS/.mntcheck and then the other too.

@Wayne-Workman I believe these are the logs you asked for. The second on just repeats itself through today.

I will check on those other settings. Thx.

[Wayne Workman]

@ManofValor Also you should try updating again. For issues with FOG, it’s very very likely that Tom fixed it literally a minute after you posted. Updates are pushed all day long, most days.

[Tom Elliott]

@Wayne-Workman what error in the code base?

[Wayne Workman]

@Tom-Elliott FOG Configuration page in whatever version ManofValor is running throws a “Not Found” error.

[Tom Elliott]

@Wayne-Workman It’s not anything FOG is doing.

[ManofValor]

@Wayne-Workman Just updated again but still getting same error, though it did not go to the update page. I’m on version 7979.

[Tom Elliott]

@ManofValor What error?

THe 404 static/index.html?

[ManofValor]

@Tom-Elliott yes

[Tom Elliott]

@ManofValor well, why?

WHat’s int he apache error logs?

[ManofValor]

@Tom-Elliott This is from yesterday.

[Tom Elliott]

@ManofValor Who’s been playing with your http configuration information?

Yesterday isn’t any good either, though. Is this off the NAS or off the main server? Is SELINUX enabled on this CENTOS box? What about firewalls?

[ManofValor]

@Tom-Elliott It’s off the main server. More than likely I did something. I’ve been learning how to connect my NAS to my fog server and yesterday I setup a new storage node for the NAS. So somewhere in there I’m sure I screwed something up. If I did it I don’t know what.
SELinux is disabled and the firewall:

[root@localhost httpd]# service iptables status
Redirecting to /bin/systemctl status  iptables.service
● iptables.service
   Loaded: not-found (Reason: No such file or directory)
   Active: inactive (dead)

[Tom Elliott]

@ManofValor assuming this is centos 7, the commands we need would be:

sestatus
systemctl status -l firewalld

[ManofValor]

@Tom-Elliott

[root@localhost httpd]# systemctl status -l firewall
● firewall.service
   Loaded: not-found (Reason: No such file or directory)
   Active: inactive (dead)

[Tom Elliott]

@ManofValor you didn’t do the commands as I typed them.
