mounting nfs failing

[r_al_sim]

hi can any one help fog seems to be unable to mount the image in the deploy or image process, I however can access the nfs shares fine from my ubuntu laptop so the fog server is certainly listening and responding on the nfs ports.

I have tried to manually mount the nfs from debug boot but i get connection timed out same error the fog console shows when deploying an image

I have followed the nfs troubleshoting guide, its not firewall, its not vlans, its not the fact nfs isnt listening

the output of showmount -e on the server is

root@fogserver:/home/fogproject# showmount -e
Export list for fogserver:
/home/fogproject/images/dev *
/home/fogproject/images *
root@fogserver:/home/fogproject#

tried a few manual mount commands i’ve found in the forum but nothing works from the fog boot image

if i run uname -r on the debug image i get 4.19.48

some one must be able to point me at what i’ve missed

here are the folder permissions and the mntcheck files

the server is on ubuntu 19.04

some heavy searching and came across this

looks like editing the init image might resolve it

So you can duplicate the issue in debug mode? Where the FOS Linux client can’t connect to the NFS share on the FOG server?

i found the problem single core VM added a extra core and mounts work fine

@r_al_sim Just for clarity, you added a second vCPU to the fog server and that resolved the mounting problem? Are you able to replicate the problem by removing the second vCPU again?

@george1421 i did further testing it seems to be end point related not server i turned the vm into a dual core machine and 2GB of ram and the PC i was running it on at the time imaged with no problems, worked fine, turns out the PC i used was the key .

so to update problem still exists can’t mount filesystem on one PC but can on another

both booting via ipv4

Are those both on the same network switch?? Same subnet?

What is different between these two computers? Is it model number, cpu, network adapter, physical location that makes one work over the other?

[r_al_sim]

Network similarities are as follows
Same network same switch same router

differences are as follows
motherboard
Bios
network adapter
CPU
(everything)
its a uefi bios

the network adapter

I have 4 different PC models scattered about the place and get different results on them all some boot and mount the nfs others time out
