Fog hangs while trying to upload

[Scootframer]

@lukebarone Thanks for the all the assistance Luke. I am still able to deploy my images which is the most important thing. If you think of the solution let me know.

Thanks,
Scott

@Scootframer So capturing an image has worked before just fine as we see from the images directory. It’s on a local LVM storage, XFS format. Does not look like something causing trouble in general.

What happens at this stage is simply a chmod -R 777 /images/a4bb6d84ebf4, so setting access rights to allow full access for everyone on this directory. I really have no idea why it would hang here. In the step “Preparing backup location” just before this one the directory is being created, which obviously does not hang or error out.

You might wanna try a debug capture (go to where you would schedule a normal task but in the last step you can tell to run in debug mode). Boot up the PC and hit ENTER twice to get to the shell. Then start the process by running the command fog and start stepping through it. Then just before the “Setting permission location” step you wanna stop the run via ctrl+c. Then run chmod -R 777 /images/a4bb6d84ebf4 and see if that’s returning or not.

@Sebastian-Roth Hi Sebastian,
I ran through the steps that you recommended I try. After hitting ctrl-c after the “preparing backup location” and typing in your chmod command it just leaves me with a blinking cursor on the next line. I tried to upload a pic of it but I just get an error on upload.

@Scootframer Do you get anything in the server logs?

dmesg | tail
tail /var/log/syslog /var/log/messages
journalctl -f

@Scootframer
I found some things on some of these errors that suggest stopping or restarting the nfs service on the server, that doesn’t seem like the best workaround, but could be something.
What pxe boot file are you using? Have you tried reverting to an older kernel or init? You can download the bzImage with a different name in the kernel downloader within the fog gui and then set the host you’re capturing to use the alternate test kernel (so you’re not changing the kernel that you know is working for deploying images). i.e. go download the previous kernel from what you last updated and name it bzImage-test and then on the host your capturing put bzImage-test in the hosts kernel field in the fog gui and redo the debug capture steps and see what happens.

Also, are you able to run the chmod command on the server (instead of from the client in the debug session)?

Yeah definitely restart your whole FOG server as suggested by @JJ-Fullmer as well.

[Scootframer]

@JJ-Fullmer I appreciate everyone’s assistance on this issue. We are due for a Server upgrade next month so we are going to put this issue on hold, wait till April and create a new Fog server.
I did download an older Kernel from Sept of last year and renamed as you recommended and had Fog use the alternate kernal for that client. Same issue happened. After doing the Upload Debug steps, ctrl+C and tried the chmod (tried on client and server) it said directory not found? What the heck?
Thanks again for all the great advice. I will keep you guys on speed-dial and hope not to need you when I create our new Fog server next month.

[Sebastian Roth]

@Scootframer Have you done a server reboot yet? From what I read this would fix the current issue you see.

[Scootframer]

@Sebastian-Roth Yes, first thing this am after reading my notifications I rebooted the server.

[Sebastian Roth]

@Scootframer Do I get this right? The issue persists even after the server reboot?

[Scootframer]

@Sebastian-Roth Indeed it does, gets stuck in the same spot. When I ran the chmod it said the directory didn’t exist.

[Sebastian Roth]

@Scootframer Maybe the server’s disk is failing? Have you checked the disk’s SMART bearings yet?
