I have a fedora 31 server with nfs server installed. Suddenly the nfs-server service wont start again. It is in the status activating (start-pre). All other services rpcbind, rpc-gssd, nfs-mountd etc. are running. Has anyone a hint for me why the nfs-server is not starting?

Hi @markusroth. Did you’d tried the updates and reboot (just to see if this service can work at all for now)?
First run:
systemctl restart nfs-server.service
journalctl -xe -u nfs-server.service
and then give us the output of the last restart attempt.

I found that the start-pre command is exportfs -r . Thist recreates the file /var/lib/nfs/etab. It reads the content of the /etc/exports file and the files under /etc/exports.d/ . If I start exportfs -r manually it does nothing and the etab file is empty. I deleted the etab file, disabled the nfs-server and reboot the system. After this I ran this command exportfs -v -r. The etab file was created with the correct content.
I realized that the nfslcd.service failed to start. I found a thread [Solved] nfsdcld issue / Kernel & Hardware / Arch Linux Forums which give me the solution for this error . The last reply in this thread explained to stop the nfslcd.service before and delete the files /var/lib/nfs/nfsdcltrack/main.sqlite AND /var/lib/nfs/nfsdcld/main.sqlite. Then I rebooted my server and start the nfs-server.service with systemctl start nfs-server. Now it run!!!
