mounting nfs failing



  • 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



  • 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

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

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

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



  • @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

    @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?



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

    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?



  • some heavy searching and came across this

    looks like editing the init image might resolve it
