Problem with 'permission denied' after FOG server restart
-
[quote=“Uncle Frank, post: 42937, member: 28116”]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…[/quote]
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).
root@VEI-3000D:/home/administrator# sudo mkdir -p /mnt/nfstest && mount -v 10.0.2.250:/images /mnt/nfstest
mount: no type was given - I’ll assume nfs because of the colon

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.
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

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!
-
Before restart,
Make sure the port=0 is not commented otherwise dnsmasq tries to act as the dns provider which is likely what is your internet problem.
-
Thanks Tom! That did it!
I had database issues with the restart, though. It wanted me to update the database (as during initial installation) and when I clicked it, I received a long list of errors due to the database already being there. I followed some of the fixes on modifying the config.class.php and .fogsettings with no luck. I re-installed FOG which required me to do some dnsmasq changes as well. FOG is working again, but I’ll continue to restart and try more fixes.
Thanks again!!!
