Here's how to mount an nfs share:

#cat /etc/systemd/system/mnt.data.mount

[Unit]
Description=nfs mount script

[Mount]
What=192.168.0.30:/mnt/tank/Media
Where=/mnt/data
Type=nfs4

[Install]
WantedBy=remote-fs.target

I’ve always mounted network shares in fstab, what’s the benefit to doing it with systemd?

(Also, for those of you learning, this method only works on systemd-based distros)

[–] Still 8 points 1 year ago

you can stop and start it via systemctl and systemd is going to make mounts for fstab entries automatically, I just put local drives in my fstab so that way I can copy mount files between machines

[–] [email protected] 5 points 1 year ago

With these systemd mount files I don't need to touch the fstab, I can use ansible to copy the file, enable the service then start it. I can also have other services like Docker, Jellyfin or whatever to depend on that service. If the nfs share can't be mounted then systemd won't try to start docker.

[–] [email protected] 2 points 1 year ago

Systemd can retry mounting based on the restart policy in case you have an interruption.

[–] [email protected] 6 points 1 year ago (2 children)

Kinda interested now, why would you use systemd script for this instead of fstab ?

[–] [email protected] 2 points 1 year ago

So you can easily start and stop it as a service and you get your logging easily accessible via journalctl as a unit. But practically speaking there's not much difference.

Oh that's actually really good reason with docker containers that rely on the NFS share. Thanks, I'm gonna steal this

[–] [email protected] 6 points 1 year ago

Yeap! You can even make an automount unit too! That way it’s mounted on demand! Makes life sooo much easier. I even do it for my external drives I use for backups

Meanwhile I found a solution using fstab.

What's the advantage of using a systemd script?

I'll probably switch to simple script, since I don't like the idea of my laptop shouting my NAS access credentials into any available random network on startup.

[–] [email protected] 3 points 1 year ago (1 children)

How would you do this with fstab? (Working with an smb share which I'm assuming is standard)

You may want to consider adding nofail and x-systemd.device-timeout opinions on the mount as well if the NFS isn't critical to the device booting, and speed up your boot process a bit.

[–] [email protected] 3 points 1 year ago

That sounds useful, thank you very much.

An now explain how to setup Kerberos

What=Kerberos
Where=pam
[–] [email protected] 1 points 1 year ago

No idea, I don't use Kerberos.

[–] [email protected] 0 points 1 year ago

Oh that's easy! I have this friendly multi-page PDF that assumes you have an active directory domain already (god rest your soul if you're raw dogging kerberos and ldap raw) that walks you through the instructions step by step and...

Googling an issue and copy pasting the first terminal code you see on the first result.

[–] [email protected] 10 points 1 year ago

It looks like the command you're trying to paste contains danger---

yes, yes I know what paste is let gooooo

Googling is so difficult for a Linux noob, and it takes a whole weekend to go through forums looking for solutions and commands to paste. I'm having much more success asking ChatGPT. ChatGPT and the Steam Deck have been the biggest factors in making me use Linux more and more.

[–] [email protected] 2 points 1 year ago

Oh wow, why haven't I thought about asking chat gpt? That seems like a good place to start.

[–] [email protected] 1 points 1 year ago

I remember when Valve first announced SteamOS in 2013. It made me start to tinker with Linux. I ended up setting up and breaking (so much breaking) an OMV install on my old gaming PC turned NAS.

[–] [email protected] 8 points 1 year ago

I use SSHFS and some pretty simple helper scripts for all my shared folder needs. Works pretty well IMO. I've never really used NFS nor mounted SMB shares on a Linux machine.

[–] [email protected] 8 points 1 year ago (1 children)

Something that works fairly well for me:

  • Make a copy of the file you're working sudo copy /etc/fstab /etc/fstab.bak
  • Ask a particular question to ChatGPT How do I mount a samba share in Ubuntu Server 22.04?
  • Read through the commands and try them out. ChatGPT is great for stuff like this, especially with follow-up questions, and giving you detailed info on error messages.
  • If you fubar, then simply restore your backup file and try again.

  1. ChatGPT gives bad command, system fails to boot
  2. Drops into emergency shell
  3. Ask ChatGPT how to fix fstab from emergency shell
  4. Goto 1), rinse and repeat

You can also replace ChatGPT with Devin and achieve the same results*

*Your mileage may vary depending on the quality of your Devin

I saw that you figured it out using fstab. Since it's a network share, you may wanna check out autofs too.

[–] [email protected] 4 points 1 year ago

I'll definetly look deeper into this, thank you very much.

Me, trying to create a compressed tar archive

Compress Zee Vucking Files: tar -czvf out.tar files.

I know the image you mean, but I can't find it.

I always say out loud "Compressed Zipped Verbose File" or "eXtract Zipped Verbose File"
