Problem with 'permission denied' after FOG server restart
-
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.

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.

Looks pretty good! I just don’t understand why you don’t see this when connecting with NFS…
-
It is a head scratcher, for sure! Do you think a re-install is in order at this point?
-
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!
-
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.
-
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.
-
I have finished the re-install and so far so good! I am both capturing and deploying images, even the laptop I initially noticed the problem with is taking the restored-from-back-up image.
I am currently restoring the rest of the images and will test more tomorrow. I will even restart the FOG server and hope this doesn’t happen again! Haha!
At this time, I think all of the ‘fixes’ for me trying to get the original TFTP timeout issue resolved (before I tried dnsmasq) may be the cause for this. With my inexperience with Linux I was trying what worked for others without actually knowing what I was changing.
The only issue I seem to have now is after I installed dnsmasq, I can no longer browse the internet. It’s a dns issue, for sure, as I can ping IPs, just not names. This also was happening before I re-installed. I’ll work that issue out with the dnsmasq peeps.
I will update after the re-start!
