nfs_export Stale file handle

[Carl Karsten <carl@xxxxxxxxxxxxxxxx>]

I am sure this worked once, then I rebooted and now something ....

root@negk:/srv/nfs/rpi/root# mount -v -t overlay -o nfs_export=on
overlay -olowerdir=img,upperdir=upper,workdir=work merged
mount: /srv/nfs/rpi/root/merged: mount(2) system call failed: Stale file handle.

# this works:
root@negk:/srv/nfs/rpi/root# mount -v -t overlay -o nfs_export=off
overlay -olowerdir=img,upperdir=upper,workdir=work merged
mount: overlay mounted on /srv/nfs/rpi/root/merged.
root@negk:/srv/nfs/rpi/root# umount merged

# syslog:

[   80.317697] overlayfs: failed to verify origin (root/img,
ino=2374476, err=-116)
[   80.317703] overlayfs: failed to verify upper root origin

# no help:
systemctl disable nfs-server.service
reboot
root@negk:/srv/nfs/rpi/root# systemctl status nfs-server.service
