Odd NFS issue

[pugnacious]

Well, the fog server accepts the node now, however it doesn’t move the images from the dev folder, and I can’t deploy the image to another machine. I’m obviously missing something.

[Wayne Workman]

@pugnacious You’re missing the FTP piece. FTP is what moves images from /images/dev to /images

This article is more specific to FTP on Linux, but should help you: https://wiki.fogproject.org/wiki/index.php?title=Troubleshoot_FTP

That was the first thing i checked. The FTP is working on the storage node server. I can connect and create/delete/download/move files.

Good, but can you connect and do that stuff using the credentials that are set inside of the storage node’s settings in the fog web interface?

[pugnacious]

Yes, I verified all the credentials just in case. The only thing I could think of was perhaps a space in the storage node name or the lack of a trailing slash on the path. I just recreated the node and re-verified everything in the config just to check. I’ll know in about 4 minutes. The good thing about using the node on the company NFS server is that the upload speed is about 4 GB/min which is amazing. Now if I can just get the image to go the other direction.

@pugnacious The FTP Path matters. if you FTP in, and change directory to /, and look around, what do you see? is this the expected root directory?

The path from / to wherever the images folder is, is what the FTP path should be.

Does cd / work ?

[pugnacious]

If i connect to the FTP server, type the command to change directory to the root, it defaults to inside the images folder. Should it be one directory up?

[Wayne Workman]

@pugnacious That’s fine. That means your FTP Path is /images

[pugnacious]

Well, it failed to work yet again. Is there anything I can check to find out what’s not working? I’m trying a debug capture now.

That’s what I would probably have suggested next.

Since you’ve already uploaded, you don’t need to again. Just try to manually move it yourself via command line using the host’s debug environment.

Also, pay attention to the variable dump. Maybe something is screwed up there?

[pugnacious]

What command does fog use to move it? Also, Ctrl + C to drop out of the script, correct?

I’ll find out… stand by…

Yes.

[pugnacious]

standing by. I’m taking notes as I run into issues, so perhaps in the future, some other person might benefit from my roadblocks.

I mount my /images from an attached array straight into the /images folder and it works without issue. But I’m using ubunutu 14.04 and the drive is formatted as ext4. But regardless I imagine it would still work.

What does your /etc/exports look like?

cat /etc/exports

what does your /etc/fstab say? That’s where the options for mounting it in the os would be

cat /etc/fstab

what are the permissions currently on /images?

ls -l /images

Are you on the latest trunk of FOG 1.2? I think FOG 1.2 had a fogstorage user that needed permissions to the storage nodes and its password needs to be set correctly in the gui storage node settings.

Does the graph of the space usage display on the fog gui homepage?

Are you able to mount the nfs drive elsewhere?
for example if you happen to have an enterprise version of windows install the
“client for NFS” in the “turn windows features on and off” found in the “add or remove programs” control panel.

If that client is installed you can mount an NFS share in windows by either
running this command in a run prompt…

\fog-server\images

or
In command line

mount \\fog-server\images Z:
cd /d Z:
Z:\>dir
images directory listing pops up

Granted @Wayne-Workman is probably right saying you should add it as a separate storage node since its hosted on a different machine and a different OS and all. But some of this might help troubleshoot this if getting it to work is possible through your current configuration

[Wayne Workman]

@Arrowhead-IT He’s working on making a storage node work on Windows.

@pugnacious said:

The file that does it is /var/www/html/fog/service/Post_Stage2.php

[Wayne Workman]

@pugnacious Looks like it’s two commands, back to back. a rename, and then a put.

if (!$FOGFTP->rename($dest,$src) && !$FOGFTP->put($dest,$src)) throw new Exception(_('Move/rename failed'));

We’re going to do this the easy way.

Edit this file: /var/www/html/fog/service/Post_Stage2.php and around line 23 where you see this:
if (!$FOGFTP->rename($dest,$src) && !$FOGFTP->put($dest,$src)) throw new Exception(_('Move/rename failed'));

Change that to:

if (!$FOGFTP->rename($dest,$src) && !$FOGFTP->put($dest,$src)) throw new Exception(_('FAILURE-- Destination: ' . $dest . 'Source: ' . $src));

That will output the destination and source on the screen. This will help us figure out what’s wrong.

[Wayne Workman]

@pugnacious This is probably a good time to ask… what error are you getting at the end of the upload? FTP Connection has failed! or Move/rename failed

[pugnacious]

I just got back to the office. I’m running it again now and i’ll know in a few minutes. Thanks for checking up.

[pugnacious]

It’s moving too fast for me to see the error message. Would a copy of the FTP logs help (edited to remove security details of course)?

From this, it looks like it’s deleting the files, and directory and then quitting instead of moving the files.

Anyway, I won’t be back until monday. I’ll check any reply then.
