I cannot reproduce the problem.

Oh, I can reproduce it. I just reproduced it 3 hours ago.

Now you have to understand that the way permissions work in Linux is foreign to native Windows users. Let me grab the full log:

(Okay, the heads up here is that I moved the entire contents of one directory (~/GNS3/projects/nat-cloud-combo) to another directory ( ~/GNS3/projects/personal/dhcp-snooping/IOSvL2-15.2.1 and I successfully moved the files,

But the .gns3 file showed up as me not being able to write to it. ( I wanted to change the name of the titlebar from nat-cloud-combo to dhcp-snooping-iosvl2-15.2.1 in the windows gui in the .gns3 file ) But I did know I did not have permission to write to the file when I began editing it in vim.

I have looked at the log again. It is 522 lines long and it is very confusing. I used the mv command to move the files from nat-cloud-combo to IOSvL2-15.2.1, but I broke the .gns3 file in IOSvL2-15.2.1 so I had to destroy the IOSvL2 directory and all it's directory.

I fixed it my problem. But I really do not understand what I did.

I am not deleting any lines in my logs - I just do not do that.

This is Ubuntu 18.04 and there is some thing about mv and cp that may, or may not, be affecting GNS3.

Again, no lines are deleted. Sorry.

shrug I have everything working.

ghost commented 4 years ago

Oh, the primary cause of the me dropping into terminal mode was that in GNS3 2.2.10 on my Ubuntu 18.04, which is run via the local server only enabled, that the "save project as" did not work. I do not know if I had the console working and my ubuntu machine does not log everything like my windows machine logs things that's in my to do bucket.

The GNS3 2.1.10 while fully working with this IOSvL2 project does not show as a "Recent Project" - now that is a totally different issue. But that issue has existed the last 5 restarts of GNS3. My IOSvL2 project is open right now and is active and the gns3_server.log - I am sure - is running merrily along at a debug level 0 - I will fix that debug level 0 before the sun goes down.

I just ran into the same problem. I am using GNS3 2.2.49 on VMWare ESXi (VM version: 0.16.0), and also use docker in my project.

This is the error I got:

Could not create snapshot file '/opt/gns3/projects/8fea4433-4b7e-4c65-a2eb-45bb978dd9cb/snapshots/decor_200924_071023.gns3project': [Errno 13] Permission denied: '/opt/gns3/projects/8fea4433-4b7e-4c65-a2eb-45bb978dd9cb/project-files/docker/35bfca08-2a07-46e4-8b29-cf54d1a12022/var/lib/clickhouse/user_scripts'

I am not sure the second line is relevant. It shows up as a warning, not an error. Regarding the first one, this is what I see as root user in the filesystem:

The gns3 user cannot ls the user_scripts directory, and probably not most of the others as well.

Is there any known workaround?

grossmj commented 5 days ago

Do you know if I can access the Docker image you use so I can reproduce the problem on my side? thanks.

yoennb commented 5 days ago

Hello, I have tried to reproduce the error on a new project, but now the owner of the files listed above on the new container is gns3, therefore the snapshot / export process runs correctly. I don't know what I did the first time that led systemd-resolve own these files. I will try to dig a bit deeper and see if I can reproduce the error on another image.

yoennb commented 5 days ago

Ok, so now I understand a little better. systemd-resolve corresponds to the clickhouse user id on the docker image I am using (clickhouse/clickhouse-server), and it is the user which creates these files/directories at first. Then when the container is stopped, gns3 transfers the ownership of all these files under project-files/ to itself. However, for some reason I cannot explain, my initial project contains some directories under /opt/gns3/projects/.../project_files/docker which belong to containers that do not exist anymore, and these directories were not deleted as they should have been. Plus, the ownership of the content of these directories was not transferred to gns3, hence the error. Maybe the gns3 VM was accidentally powered off suddenly and things were not properly cleaned up.

Ok no worries, please let us know if you see the problem again 👍
