Unable to deploy - No route to host

Mashley

I am unable to deploy images. I see a similar problem in this forum post but I’m still getting the same error after working through what I could: https://forums.fogproject.org/topic/9677/could-not-mount-images-folder-bin-fog-upload/2
I have FOG installed on an Ubuntu VM.
I have followed the Troubleshooting NFS wiki ( https://wiki.fogproject.org/wiki/index.php?title=Troubleshoot_NFS ), however, I am still getting the error:

Mounting File System …Failed
Could not mount images folder (/bin/fog.download)
Args Passed:
Reason: mount: mounting 10.0.4.25:/images on images failed: No route to host

The FOG server IP address is correct.

My /etc/exports file is correct and is as follows:

/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)

Even more strangely, I can register a host from the FOS and when I attempt to do that or join a multicast session, FOS allows me to use the “fog” user to start that. That got me thinking - the FOG user manager GUI shows a user named fog, so I’m assuming that’s the one, but I’m not seeing it as a user in my server, as shown above; I only have users called fogserver and fogproject. Is it possible I deleted the main user and that has messed something up?

GUI showing fog user:

This is my third build and I feel like in all the troubleshooting, I must have done something small but significant to prevent this from working. Any help is welcome and appreciated.

PS - I was able to deploy a single image at some point… I can no longer do that and I’m not sure when that happened.

@mashley said in Unable to deploy - No route to host:

Reason: mount: mounting 10.0.4.25:/images on images failed: No route to host

This right here concerns me. Why wouldn’t the pxe booting computer have a route to 10.0.4.25 (assuming that is your fog server IP)? I would have previously had a route since iPXE was loaded to get the FOG menu and bzImage was also downloaded.

So to the questions.

Is the FOG server and pxe booting client on the same subnet?
Is there some kind of screening router/firewall that is sitting between the FOG server and target computer, where it might be filtering out the NFS protocol?

Mashley

@george1421 Thanks for your response.

You must be on to something here. I was able to PXE boot and I was also able to unicast to that lab before, and somewhere along the way, I no longer can. When could it have lost that route? I’m sure there’s a solution if I messed up a configuration along the way.

The client and FOG server are on different subnets.
There is a firewall that I don’t (yet) have access to.

george1421

@mashley If you want you could debug this a bit more, or wait until you can review the rules on the firewall.

Mashley

@george1421 Thanks. I’m going to debug a bit more next time I’m in the office.
