Mounting network shares with autofs (alternative to fstab)

Ariux · 9 May 2020 18:17

I am using AUTOFS NFS on my vero 4K and it is really good. But if i restart my vero 4k I can not watch my movies, because I am loosing connection until I ssh to my vero 4K and restart autofs with comand sudo systemctl restart autofs

This is what I do not like. Is it expected behavier of AUTOFS after restart of vero 4K?

After reboot, what is the output of sudo systemctl status autofs?

Ariux · 9 May 2020 18:42

osmc@osmc:~$ sudo systemctl status autofs
● autofs.service - Automounts filesystems on demand
Loaded: loaded (/lib/systemd/system/autofs.service; disabled; vendor preset:
Active: inactive (dead)

ActionA · 9 May 2020 18:45

Run sudo systemctl enable autofs && reboot then check if the mounts are active when the machine comes back up.

Ariux · 9 May 2020 19:01

I entered as you advised sudo systemctl enable autofs && reboot
Vero 4k restarted when I connected by ssh and interned again

osmc@osmc:~$ sudo systemctl status autofs
● autofs.service - Automounts filesystems on demand
Loaded: loaded (/lib/systemd/system/autofs.service; disabled; vendor preset:
Active: inactive (dead)

After that I entered:
osmc@osmc:~$ sudo systemctl restart autofs
osmc@osmc:~$ sudo systemctl status autofs
● autofs.service - Automounts filesystems on demand
Loaded: loaded (/lib/systemd/system/autofs.service; disabled; vendor preset:

It works perfect, but after power failure, or if I restart Vero 4K myself my mounts by AUTOFS is not active…

That should have changed

osmc@osmc:~$ sudo systemctl status autofs
● autofs.service - Automounts filesystems on demand

Into

osmc@osmc:~$ sudo systemctl status autofs

That’s what I expected too!
When the unit is enabled then it should start on boot everytime.

What output is returned when issuing sudo systemctl enable autofs?

Ariux · 9 May 2020 19:30

Thanks for your help ActionA
Here is the output, but it is not after restart of the vero 4k, but after restart of AUTOFS

Run sudo dpkg-reconfigure locales , de-select anything you find with an asterisk except for en_US.UTF-8, and select Ok. On the next page, I also select en_US.UTF-8. as the default locale for the system environment on the next page, and again select Ok. Grab a cold refreshing beverage while the process completes, then try to sudo systemctl enable autofs. Use the status command we used before and check that the unit reports as enabled.

Ariux · 9 May 2020 20:08

I entered as you adviced: sudo dpkg-reconfigure locales
Actually it was selected just en_US.UTF-8 . I scrolled all the way down and selected OK. On the next page I selected en_US.UTF-8

And here is my output actually not sure is it ok. I will reboot my Vero 4K and check will it mount automatically AUTOFS

Generating locales (this might take a while)…
en_US.UTF-8… done

Great! So after reboot, you are now finding your mounts in place and functioning?

Ariux · 9 May 2020 20:27

Yes after reboot, I am finding my mounts in place and functioning.
Already restarted 3 times and all 3 times is Ok. Really thanks ActionA:+1:

ActionA · 9 May 2020 20:27

No problem! Enjoy OSMC!

H @fzinken,
I suggest indicating in what syntax to add NFS mount options to the /etc/auto.nfs.shares - I had to Google it elsewhere. I tried to filter out the options that may be downgraded in the negotiation but will not limit the performance from the suggestions of @THEM in thread Consistently interrupted playback - #6 by THEM
My suggestion is:

/mnt/TV-F -fstype=nfs,noatime,nolock,local_lock=all,async,rsize=1048576,wsize=1048576 192.168.0.1:/TV-F

The rsize and wsize may be downgraded if server does not allow that big, but we mostly deal with streaming big files anyhow, so the bigger the better
Locking does not usually happen, but better just disable remote and local alike
async should be default, but let’s just try and force it
let’s not update atime at all (otherwise it defaults to relatime for me that I know is almost as efficient, but this is the most performant available)

All this and other choices helped me to get very close to the theoretical bandwith of Gigabit Ethernet in Buffering issues - #34 by petersasi.

rhodesda · 28 May 2020 14:28

@fzinken is it possible to use credentials for nfs using autofs, the above examples only show using creds in smb

Tom_Doyle · 28 May 2020 18:42

HI,

yes, but the NFS server would need to support it, probably kerberos.

Thanks Tom.

hdmkv · 6 June 2020 15:03

The IP address of one of my servers changed after it rebooted following a firmware update. What are the commands to edit the mapped/mounted share on Vero?

I can see the share I need to edit when I do ls -lah /mnt/ … but how do I edit? Thank you.

fzinken · 6 June 2020 15:09

just edit the IP in your auto.smb.shares or auto.nfs.shares file depending on which one you use.

hdmkv · 6 June 2020 15:15

@fzinken to the rescue again, thank you sir. Simply typing auto.smb.shares returns a command not found error. Sorry, don’t know the exact commands to enter.
