Problem with 'permission denied' after FOG server restart

[mecsr]

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.

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!

[mecsr]

The image files are all there right sizes and all.
exportfs -a gave a bunch of errors

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

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…

[haste347]

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 exist

root@VEI-3000D:~# sudo umount /nfstest
umount: /nfstest: not found

root@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 exist

root@VEI-3000D:~# umount /nfstest && rmdir /nfstest
umount: /nfstest: not found

And, 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!!!

[Sebastian Roth]

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?

[Tom Elliott]

It’s a default to set /images or whatever value you type in.

[haste347]

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).

[Sebastian Roth]

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]

[haste347]

Below are the results of the commands.

root@VEI-3000D:/home/administrator# sudo mkdir -p /mnt/nfstest && sudo mount -v 10.0.2.250:/images /mnt/nfstest
mount: no type was given - I’ll assume nfs because of the colon

Oddly enough, I have done some testing and I am able to capture images via FOG. However, I receive the ‘permissions denied’ error any time I try to deploy an image using various workstations and images. Any ideas on why this is happening?

Thanks again!

[Sebastian Roth]

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.

[haste347]

Hmm, I seem to have some issue with getting the info posted. I cannot attach the plain text file, and when I try to post as I have been posting, it says it is spam.

Here is the output of what I am able to get by the spam filter. It basically continues down listing each of the images similar to the “VEIGoldenImage” and “VEIUbuntu1404x647010” files below.

[Sebastian Roth]

Looks pretty good! I just don’t understand why you don’t see this when connecting with NFS…

[haste347]

It is a head scratcher, for sure! Do you think a re-install is in order at this point?

[Sebastian Roth]

Hmmmm. I personally don’t like reinstalling just for gods sake. Might fix it but you’ll never know why… If that’s ok with you give it a go!

But before that please check your /etc/exports again. I am very sorry to say this but I checked the code from your very fist post character by character just now. Yours looks like this (is that correct???):
[CODE]/images *(ro_sync,no_wdelay,insecure_locks,no_root_squash,insecure)
/images/dev *(rw,sync,no_wdelay,no_root_squash,insecure)[/CODE]

But on my system it looks like this:
[CODE]/images *(ro,sync,no_wdelay,insecure_locks,no_root_squash,insecure,fsid=1)
/images/dev *(rw,sync,no_wdelay,no_root_squash,insecure,fsid=2)[/CODE]

See the differences?? ‘ro_sync’ should definitely be ‘ro,sync’ and I guess those ‘fsid’ parameters at the end are there for a reason too!

[Tom Elliott]

The fsid isn’t always needed, but some OS’s require it as a “priority” ordering of sorts. It doesn’t hurt TO have them, but it also doesn’t hurt to not have them.

[haste347]

Ahh, my fault, sorry, I was typing with my head over my shoulders. Here is an actual copy/paste of the etc/exports

/images *(ro,sync,no_wdelay,insecure_locks,no_root_squash,insecure)
/images/dev *(rw,sync,no_wdelay,no_root_squash,insecure)

I too, don’t like re-installing as we never find out the cause. However, another install would help my experience doing so, and doing a fresh setup knowing I will need to use dnsmasq would be good for me as well.

I’ve got a back-up of all the created images anway, which makes it even less of a hassle.

I certainly appreciate all of the awesome help you’ve provided!

I will update after I get the install complete.
