NFS server daemon fails to start at boot
I´m trying to export an external disk, so, I configured my nfs-server service to wait for disk1 to mount, however it fails.
This is the situation after boot:
$ systemctl status nfs-server.service
● nfs-server.service - NFS server and services
Loaded: loaded (/etc/systemd/system/nfs-server.service; enabled; vendor preset: enabled)
Active: failed (Result: exit-code) since Sun 2020-04-26 14:46:28 CEST; 3min 7s ago

If I just restart the service it just works smoothly
$ sudo systemctl restart nfs-server.service
$ systemctl status nfs-server.service

I configured the service to "Requires" and "After" disk1 mounts, but it didn´t work:
# /etc/systemd/system/nfs-server.service

I was letting the system to automount the disk. I´ve just configured the disk to mount in /etc/fstab following to Gerald question and it just worked!. Thank you very much, guys.
I have problems with Error of nfs server daemon fails on booting process. I don't know exactly why, but the problem was from LVM.
Before the reboot I remove my LV, VG and PV. I make the mount permanent by adding them to /etc/fstab. After removing my PVs reference from /etc/fstab my problem solved.
