Hello,
I switched from AL8 to AL9 and my NFS server stopped working.
I’ve been digging around on Google for a few days now and still nothing, still nothing, still nothing.
Is there an instruction manual somewhere to get NFS up and running on the AL9?
On the AL8, everything - installation and start-up - went intuitively by itself.
BTW: So, for instance THIS does not work: (nfs service does not exists)
That is true:
$ systemctl status nfs.service
Unit nfs.service could not be found.
$ systemctl status nfs-server.service
● nfs-server.service - NFS server and services
Loaded: loaded (/usr/lib/systemd/system/nfs-server.service; enabled; preset: disabled)
Where does the other unit file come from:
$ dnf provides */nfs-server.service
nfs-utils-1:2.5.4-20.el9.x86_64 : NFS utilities and supporting clients and daemons for the kernel NFS server
Repo : @System
Matched from:
Filename : /usr/lib/systemd/system/nfs-server.service
What other units does package nfs-utils provide?
$ dnf rq -l nfs-utils | grep service
/usr/lib/systemd/system/auth-rpcgss-module.service
/usr/lib/systemd/system/nfs-blkmap.service
/usr/lib/systemd/system/nfs-idmapd.service
/usr/lib/systemd/system/nfs-mountd.service
/usr/lib/systemd/system/nfs-server.service
/usr/lib/systemd/system/nfs-utils.service
/usr/lib/systemd/system/nfsdcld.service
/usr/lib/systemd/system/rpc-gssd.service
/usr/lib/systemd/system/rpc-statd-notify.service
/usr/lib/systemd/system/rpc-statd.service
On EL7 the nsf.service is a mere symlink:
$ ls -l /usr/lib/systemd/system/nfs.service
lrwxrwxrwx. 1 root root 18 Jan 12 2022 /usr/lib/systemd/system/nfs.service -> nfs-server.service
Neither AL8 nor AL9 has (file or symlink) /usr/lib/systemd/system/nfs.service.
In other words, one should have used “nfs-server” already in EL7, but the guide does use the old alias “nfs”.

nfs-utils is installed in last version.

That does not work,
First thing - nfsd cannot be foud:
[rna@nuc24 ~]$ sudo dnf search nfsd

?
If true, then what do you get with:
rpm -V nfs-utils
systemctl status nfs-server
[rna@nuc24 ~]$ sudo rpm -V nfs-utils
[sudo] passwd for rna:
S.5....T. c /var/lib/nfs/etab
[rna@nuc24 ~]$ sudo systemctl status nfs-server

See? You do have the nfs-server.service.
You just have to enable (and start) it, provided that you have the /etc/exports already set up and that you have updated your firewall to allow the clients to connect.
It looks more better, I will try it asap.

Thank you very much.
I don’t understand where the error was, I guess I was trying to run something like nfs or nfsd. And it should be nfs-server.
This is the case when one works on different distributions, RedHat, Mint, Raspbian…
Then I don’t have a mess in my head.
You better also:
sudo systemctl enable nfs-server
Because merely starting a service only starts it now,
while enabling it sets it to start on (every) boot.
Of course.
After trying it, I enabled it permanently.
