Could Not Mount Image

[bberrelez]

@Tom-Elliott
I run that from the machine connecting to the FOG server?

[Wayne Workman]

@bberrelez Yes.

[bberrelez]

@Wayne-Workman
Tried that. Nothing happened.

[Tom Elliott]

@bberrelez Teamveiwer maybe?
Hit me on chat.

That would be awesome! Thanks! I could do a teamviewer session. Are you just wanting to see the management console or are you wanting to actually get on the linux box?

I ran into this before too. Check that nfs-server is running by running:

systemctl status nfs-server

If it’s not, you can manually start it with:

systemctl start nfs-server

This enables the service to start automatically on next boot, but it should already be enabled…

systemctl enable nfs-server

Which brings me to telling you to follow this guide on delaying the FOG services to fix the problem:
https://wiki.fogproject.org/wiki/index.php/Fedora_21_Server#Set_the_FOG_services_to_start_30_seconds_after_boot

I needed to also add “systemctl start FOGPingHosts” to the rc.local on my CentOS 7 installation.

Two commands you can use to easily see what is/isn’t running on your CentOS 7 installation are:

pstree

&

systemctl list-units --type=service

Hello – I’m having a similar issue. I don’t want to hijack the thread, but I have checked to make sure the NFS server service has been started, and it has. If I boot into debug mode and check the current working directory, I am in the root directory – there seems to be no /images path. Again, not sure if it’s related, but I’m having the same problem.

@Vasahond

Also ensure that all of the FOG services are running by entering:

systemctl list-units --type=service

You should see see all five Fog services in my screenshot as loaded, active, and running:

Another issue I’ve seen is the nfs-server service will show that it is running, but will be inactive and exited. Also double check that isn’t the case, because it will at a glance look as though it is loaded when you check status.

To verify the Images directory exists, try the following:

cd
cd /images
ls

You should be within the directory and able to see at least a directory called dev and postdownloadscripts.

[Vasahond]

@jgurka, here is a list of my running services. A few are stopped; do you suppose these are crucial processes?

[jgurka]

@Vasahond

It looks like you’re on CentOS 6 – I was assuming you were on 7 earlier. Is this the latest trunk build of FOG, btw?

I don’t think the stopped FOG services are crucial for what your problem is, but I’d start them back up anyway:

service FOGPingHosts start
service FOGSnapinReplicator start

It looks like you have the IPv6 firewall still enabled…this might potentially be causing the problem? I’d go ahead and disable it:

service ip6tables stop
chkconfig ip6tables off

Try it again and see if it made any difference.

Really? If that’s the case, that’s almost surely the problem. Can you please post the output of find / | grep /dev/.mntcheck

Also, what output/errors do you get when you re-run the installer? You’ve also not specifically stated what version of FOG you’re using, we need this information as well.

@Wayne-Workman

Vasahond’s running services output seems to show it as existing and being mounted via NFS:

Configured NFS mountpoints:
/images
/images/dev
Active NFS mountpoints:
/images
/images/dev

[Wayne Workman]

@jgurka Yeah I saw that, but the directory could still be missing. I’m most concerned with him not seeing a /images directory on his server.

As a test, I just created a directory called /image and exported it in /etc/exports, and restarted rpcbind and nfs-server and saw that NFS was running fine, I then deleted the /image directory and then again checked NFS… still running fine. You’ll also hopefully understand that I have been bitten many times by making assumptions about things. No telling what the guy has copy/pasted into his server trying to get it to work.

[jgurka]

@Wayne-Workman

I definitely get where you’re coming from.

@Vasahond

You can try running this to see whether or not /images actually exists:

[ -d /images ] && echo 'Directory Found' || echo 'Directory /images not found'

You should see "Directory Found’ if it does in fact exist.

[Wayne Workman]

@jgurka People like @george1421 suggest to put the images in /opt/fog/images, which is why I suggested searching for /dev/.mntcheck

[plegrand]

Hello, i think i’ve got the same problem except i made modification on the web interface :
i didnt want the “images” directory be at the root (/images)
then i copy the images directory into /home/images.

Then i modify the image path on the web interface, i thought it would modify the export file also but it seems not.

then i had to modify manualy the export file. Now it works fine.
Could it be the problem ?

[jgurka]

@plegrand

The images directory needs to have full r/w/x permissions in order for FOG to use it – did you make sure to change the permissions when you created the new directory and copied the contents of the old /images?

To check the directory permissions, run the following:

cd /home
ls -la
#You want permissions on the new images directory to be drwxrwxrwx and also on sub-directories

To enable full r/w/x permissions on the folder, run the following:

chmod -R 777 /home/images
#-R will run it recursively to apply the permission changes to sub-directories as well as the top directory

I tried this and still nothing. I did find that I had an incorrect path list on the the image path under Storage management. I created a directory here: /home/fog/Images, applied the appropriate permissions and corrected the path under the storage management.

Still have the same message appearing.
Could not mount images folder (/bin/fog.upload)

Need to know information! Lol
You need to modify /etc/exports to reflect the correct path. Then reboot.

@bberrelez Can you ensure the .mntcheck files are in the /home/fog/images and /home/fog/images/dev files? Also, does the /home/fog/images/dev folder exist?

From the sounds of it, you switched to /home/fog/images after /images was already created.

Based on all of this, I’m also just guessing that this was a fresh install, and there were no images in /images.

Basically, if I can follow the issue at all:

You ran:

mkdir /home/fog/images
mkdir /home/fog/images/dev

If you don’t have the dev folder in /home/fog/images, you’ll also fail as the mount literally fails (no such directory).

If you do have the dev folder, then run this on your fog server as root:

mkdir -p /home/fog/images/dev
touch /home/fog/images/.mntcheck
touch /home/fog/images/dev/.mntcheck
