Permission Denied Capture

[Detoss]

Currently I have a Centos Fog server, I added more space on another drive. And Fog website has been setup as an additional and it shows Its been added and working. But when I try to capture an image to that storage node I get the error below.

Permission Denied:

Reason: mounting (ip) /image/dev/ on /images failed: Permission Denied.

I am pretty sure it deals with my .fogsettings

[Sebastian Roth]

@Detoss Please give us some more information. Let’s start with some basics like the FOG version you use?

And Fog website has been setup as an additional and it shows Its been added and working.

What do you mean by that?

Please run the following commands on your FOG server and post output here:

cat /etc/exports
ls -alR /images
df -h

[Detoss]

@sebastian-roth 1.5.9 is the Version-

[root@fog ~]# cat /etc/exports
/images *(ro,sync,no_wdelay,no_subtree_check,insecure_locks,no_root_squash,insecure,fsid=0)
/images/dev *(rw,async,no_wdelay,no_subtree_check,no_root_squash,insecure,fsid=1)

[Sebastian Roth]

@Detoss Seems like a little typo can make a huge difference. While I am still not really sure I think you use /image as well as /images.

While /images is on your root partition using up that space you might run into an issue with that. Seems like you wanted to move things to a separate partition but that didn’t work. Tell us more about what you have tried to setup here.

Please run ls -alR /image and post output here as well.

[Detoss]

@sebastian-roth Well hopefully there’s an easy way to correct this or just point my images to it since its where the majority of space is.

[root@fog ~]# ls -alR /image
/image:
total 0
drwxr-xr-x. 2 root root 6 Nov 10 16:17 .
dr-xr-xr-x. 21 root root 288 Nov 16 16:57 …

[Sebastian Roth]

@Detoss As the /image (no ‘s’ at the end) directory is completely empty you can simply move all your stuff into that and re-mount as /images. Run as root:

mv /images/.mntcheck /image/
mv /images/* /image/

Now edit the file /etc/fstab and change /image to /images in there. Now reboot your whole server and run df -h after the reboot to make sure the images are now on the other volume.

As well double check the storage node settings in the FOG web UI to point to /images (as it should by default).

I have encountered the same issue when I want to save the image on to another folder on a RAID1 which uses soft link.
When trying to capture the image and save it to the RAID1 folder, FOG says “Permission denied”, even its being configured as 777

[Sebastian Roth]

@Will This topic is not about a soft link like you seem to have it. Please open your own topic and post all your details there. There is no point in cross posting a different issue here.

[george1421]

@will I agree please create your own post. There are several things you can do pretty easily, its just not proper to confuse this thread.

[Detoss]

@sebastian-roth Okay it is now showing this!

I will be trying it soon as I am back in the office.

Thank you again for the help!

[Detoss]

@sebastian-roth I tried to image again, now getting Partclone fail which is a first for me- Is this related or another topic I need to open?

[Sebastian Roth]

@Detoss Please Post a picture of the error screen. You might post it here as we are not sure if it’s related or not.

[Detoss]

@sebastian-roth Is there somewhere I can grab the error log? Or do is a picture fine from my cell.

[Sebastian Roth]

@Detoss Just take a picture and upload here or on an external server and post a link.

[Detoss]

@sebastian-roth Here is what I got 90% into capture.

https://ibb.co/2vcBMyh
https://ibb.co/Hqk9Qcg
https://ibb.co/HBvMLN6

[Sebastian Roth]

@Detoss Those errors point to FOG was not able to move the captured image from /images/dev/b07b2549fe0a to /images/CSR-2020 after it successfully uploaded.

You can manually move it: sudo mv /images/dev/b07b2549fe0a /images/CSR-2020

Possible the automatic move did not work because of a permission issue. Please run ls -alR /images now that you’ve moved things and post output here again.

[Sebastian Roth]

@Detoss Update the permissions like this sudo chmod 777 /images and then try another capture.

[Detoss]

@sebastian-roth AH! that worked, may I ask what is the purpose or how it worked? I am trying to understand Linux better.

[Tom Elliott]

@detoss so getting very much details.

-rwxrwxrwx is what you see files appear as. Similar for directory but the 1st dash will usually be a d, denoting directory.

Notice there are 3 groups of rwx.

r=read=4
w=write=2
x=execute=1

First grouping rwx (left to right) = owner
Second grouping rwx = group
Third grouping rwx = other/everyone

So to make owner group and other have max permissions

777

Does this make sense or at least start to help?

There are other pieces to this but this is most likely what most people want to understand.

The chmod command is short for change mode. Mode here basically means permissions.
