[SOLVED] nfs trouble on Chimaera

Had to freshly install my file server. The system SSD was defective, data isn't affected. Now the nfs server won't start up. Error message is:

# service nfs-kernel-server restart
Stopping NFS kernel daemon: mountd nfsd.
Unexporting directories for NFS kernel daemon....
Exporting directories for NFS kernel daemon....
Starting NFS kernel daemon: nfsd mountdUsage: rpc.mountd [-F|--foreground] [-h|--help] [-v|--version] [-d kind|--debug kind]

	[-t num|--num-threads=num] [-u|--no-udp]
 failed!
# showmount -e fs090
clnt_create: RPC: Program not registered 

I don't know how to deal with this situation.

Background info: Xeon 4 core CPU on X99-E WS, 32G RAM, 256G Plextor nvme as system disk, LSI9271 supplying a RAID6 with about 5TB space, two more disks for single shares. Installed from Chimaera netinstall, encrypted LVM, openrc as init, manual installation of xorg, lightdm, Mate desktop, nfs-common, nfs-kernel-server. Latest stock kernel and backports kernels available, 5.15 is the default. It does not matter which one I do boot. The RAID6 is nicely decrypted and mounted, also the two other disks. The export file is a copy of the original one from a backup. Most of the setup I have taken from my notes. Everything should work.

The above error is shown as well during boot as when I try to restart the nfs-server. Also showmount throws an error. The duck does not give hints to this error.

Also tried to drill down how the nfs-server is started. The script in /etc/rc0.d does not contain this specific error printout. How can I find the root cause for the startup failure?

Thanks, rolfie

Re: [SOLVED] nfs trouble on Chimaera

Got the problem. It was a simple "-" in the wrong place in the /etc/default/nfs-kernel-server. I had in there:

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

Removing the dash in second option changing it to "--debug all" made the script work.

Re: [SOLVED] nfs trouble on Chimaera

Does it mean hat the rpc.mountd was not started due to the unknown option?

Exactly.
