Hi George,

Output of command as follows

clnt_create: RPC: Program not registered

I’ve checked NFS server service:

systemctl status nfs-server

and was not started showing following output:

● nfs-server.service - NFS server and services
   Loaded: loaded (/lib/systemd/system/nfs-server.service; enabled; vendor preset: enabled)
   Active: failed (Result: exit-code) since Tue 2020-02-04 21:58:25 UTC; 21h ago

Feb 04 21:58:25 geo01vfog01 systemd[1]: Stopped NFS server and services.

I was able to start it again via

sudo systemctl start nfs-server

This was the same on both the Master (normal) and Master (storage) nodes.

I’ve enabled debugging to see if I can figure out why NFS server stopped which I’m guessing is the cause of the issue I’m seeing?

sudo vi /etc/default/nfs-kernel-server

Added following and restarted NFS service

RPCMOUNTDOPTS="--manage-gids --debug all"

Also seeing loads of these errors in syslog not sure if related?

I’ll be able to confirm tomorrow when I’m back in the office that this is resolved or not.

I’m seeing a separate issue with the locations plugin doing something odd but will log separate ticket for that.

Thanks again George

regards Tom

@Kiweegie The expected output from the show mount is a list of nfs shares. The rpc program not registered is a bit unexpected.

What is the output of cat /etc/exports

Hi @george1421

output as follows on all nodes.

/mnt//images *(ro,sync,no_wdelay,no_subtree_check,insecure_locks,no_root_squash,insecure,fsid=0)
/mnt/images/dev *(rw,async,no_wdelay,no_subtree_check,no_root_squash,insecure,fsid=1)

cheers Tom

I’ve added the server setup to another ticket ref location plugin but might be of use to see here also.

@Kiweegie said in Could not mount images folder (bin/fog.download) ... failed: Operation not supported:

/mnt//images *(ro, …

While I don’t think this can cause the issue I’d still change that to /mnt/images.

Beside that I see different IP addresses: 10.166.141.199 in the picture of your initial post while that IP is not in the list you posted just now…

george1421 · Feb 6, 2020, 6:36 AM

@Kiweegie ok your exports file is correct (hopefully the double slash in the images share was a type-o. That double slash // would keep the nfs server from starting). Lets make sure we have this right. You are NOT using or storing any images in /images directory path only the /mnt/images and /mnt/images is mounted on a local hard drive on the fog server? If you are using only /mnt/images you will need to update the storage node configuration for this server and change the ftp and nfs paths.

If that was/is the case I might go about it a bit differently just to keep everything clean.

Edit: Well it would help if I would read the entire thread before responding to avoid duplicating what Sebastian posted.

Kiweegie · Feb 6, 2020, 3:17 PM

@Sebastian-Roth good spot on the // it was there in exports on geovfog02 server. I’ve now corrected that I’ll blame my poor eyesight on that one…

I’ve double checked all other nodes to be on the safe side and it was only this one.

Ignore the ip from original image was screenshot from an earlier build, albeit same error.

edit: I’ve corrected the original image to avoid confusion and also provide better image - notepad++ with Deep Black theme appplied.

Kiweegie · Feb 6, 2020, 4:06 PM

@george1421 @Sebastian-Roth

Hi both not seeing this error any more so can be marked as resolved. I was not seeing the issue before editing the // in the exports file so can’t say that was the fix. Not sure what has changed if anything here other than permissions on the images themselves within the /mnt/images directory.

Ownership was set on the folder to fogproject:root but the images are getting set as root:root. I amended this to fogproject:root again so not sure if that is needed? If so can add sticky bit to get around this perhaps.

EDIT: Ignore above comment ref permissions - some are set as fogproject:root and some as root:root - both work so the permissions is a red herring.

Thoughts welcome

regards Tom

Do you have firewall restrictions in your MPLS or the VPN tunnel?
