Problem with 'permission denied' after FOG server restart
-
Maybe take the drive out and see if the error goes away??
That’d be step one of troubleshooting, IMO.
-
What are the permissions on your directories (ls -al /images && ls -al /images/dev)?
Please try to mount the NFS share from another computer and report about any errors you see:
[CODE]mkdir -p /mnt/nfstest && mount -v 10.0.2.250:/images /nfstest
umount /nfstest
mount -v 10.0.2.250:/images/dev /nfstest
umount /nfstest && rmdir /nfstest[/CODE] -
Wayne, I have disconnected the drive, no change.
Frank, I have attached the output of the permissions. I am loading another PC with Ubuntu to help with testing.
The FOG setup should have made the share able to be mounted even after a restart, correct?Thank you again, for your help. Getting into Linux has a decently steep learning curve and I appreciate your help!

Permissions look pretty good to me! Yes, FOG should setup NFS properly even if running it a couple of times and restarting the server doesn’t hurt either (as nfs server is being started as a service at boot time). Keep us posted how you go with mounting NFS from your new test machine. -
I am having a similar problem so I tried mounting on another computer. I attached a screenshot of the output.
It said permission denied, so I tried with sudo and it says only root can do that.

Forgot to say that mounting can usually only be done by root! So use [B]sudo[/B] with all these commands…
-
I also get this error when I try to start a job with an image that worked fine with 1.2
I made sure all the options in the image management are the same as they were before and all that jazz.
I also tried the mounting again with just mounting in one command and got a wrong fs type, bad option, bad superblock error.
Screenshots attached.
Thanks again for all the help.[url=“/_imported_xf_attachments/1/1723_job from fog.PNG?:”]job from fog.PNG[/url][url=“/_imported_xf_attachments/1/1724_tried again.PNG?:”]tried again.PNG[/url]

Please run ‘sudo exportfs -a’ on the FOG server. Error message like the one you see in the web interfaces occour if there is no image stored in ‘/images/<name-of-image>’. Maybe you never uploaded one or it went missing. ‘ls -al /images’…
EDIT: And please make sure nfs client is installed (debian/ubuntu: sudo apt-get install nfs-common) on that machine that you run the tests from!
-
The image files are all there right sizes and all.
exportfs -a gave a bunch of errors[url=“/_imported_xf_attachments/1/1725_exportfs -a.PNG?:”]exportfs -a.PNG[/url]

I just installed nfs-common on mount test machine and I got a more detailed failure.
Edit: Oh an my permissions are currently set to 777 for the /images folder for the sake of testing.
Typically I have them set to 775
owner and group is fog
I have also tried setting the group to www-data[url=“/_imported_xf_attachments/1/1726_mount attempt.PNG?:”]mount attempt.PNG[/url]

Well I feel dumb,
I just had to edit the etc/exports file after updating to say
/images …
and
/images/dev…
instead of
y…
and
y/dev…Not sure why it changed itself to y as the images directory, it looks like everything is working now. Thanks again for all your help.
Thanks,

Who would’ve thought that it were wrong entries in /etc/exports… Sounds a bit like you hit the wrong keys when installing FOG. When the installer asked for the path you gave ‘y’ for ‘yes’ maybe…
-
Alright, from a workstation on the same subnet I tried the commands you listed…here are the results.
root@VEI-3000D:~# sudo mkdir -p /mnt/nfstest && mount -v 10.0.2.250:/images /nfstest
mount: no type was given - I’ll assume nfs because of the colon
mount: mount point /nfstest does not existroot@VEI-3000D:~# sudo umount /nfstest
umount: /nfstest: not foundroot@VEI-3000D:~# sudo mount -v 10.0.2.250:/images/dev /nfstest
mount: no type was given - I’ll assume nfs because of the colon
mount: mount point /nfstest does not existroot@VEI-3000D:~# umount /nfstest && rmdir /nfstest
umount: /nfstest: not foundAnd, just for further testing to eliminate the folder not being there, I tried to mount to the /images folder.
root@VEI-3000D:~# sudo mount -v 10.0.2.250:/images
mount: can’t find 10.0.2.250:/images in /etc/fstab or /etc/mtab
root@VEI-3000D:~#Thank you again for your help!!!

Was probably pretty late when I wrote this post… My fault, shoud be like this:
[CODE]mkdir -p /mnt/nfstest && mount -v 10.0.2.250:/images /mnt/nfstest
umount /mnt/nfstest
mount -v 10.0.2.250:/images/dev /mnt/nfstest
umount /mnt/nfstest && rmdir /mnt/nfstest[/CODE]
Can you see the difference? By the way… what is the IP address of your FOG server?[B]And please make sure that ‘nfs-common’ (debian/ubuntu) or ‘nfs-utils’ and ‘nfs-utils-lib’ (centos) packages are installed before you try this!![/B]

Well I actually just used the script I had posted in these forums that I made when .33b was still the dev.
I guess something changed in the installer for the images path not defaulting to /images with a y? -
It’s a default to set /images or whatever value you type in.

My fog servers IP is 10.0.2.250
Yes! There is now a difference with those commands. They seem to be working now! (I did have to install nfs-common on the workstation).

Are you sure you still get the same error when booting into FOG??
From what I can see NFS seems to be alright. But please run another test:
[CODE]sudo mkdir -p /mnt/nfstest && sudo mount -v 10.0.2.250:/images /mnt/nfstest
sudo ls -al /mnt/nfstest
sudo umount /mnt/nfstest[/CODE] -
Below are the results of the commands.

Thanks again!

Seems like there are no images being saved when you upload them. Maybe the are not moved. When you upload an image it’s first saved to /images/dev/<image-name> and moved to /images/<image-name> when it’s finished. Please run this command on the server ‘ls -alR /images’ and post the output.
