Maybe. :-) I am asking specifically about NFS4. It is not obvious from your example that the remote volume is being mounted using NFS4. As for my configuration, in /etc/nfs.conf, I have set: [nfsd] vers2=n vers3=n Apart from that, it has the Fedora 32 installation defaults. /etc/exports looks like: /my-export-root/foo *(rw) Unfortunately, I haven't been able to turn up any useful log messages on either side. -- Braden McDaniel <braden@xxxxxxxxxxxxx> _______________________________________________ users mailing list -- users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe send an email to users-leave@xxxxxxxxxxxxxxxxxxxxxxx Fedora Code of Conduct: https://docs.fedoraproject.org/en-US/project/code-of-conduct/ List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines List Archives: https://lists.fedoraproject.org/archives/list/users@xxxxxxxxxxxxxxxxxxxxxxx
