Share a ssd from a raspberry on my local network and mount it on Cloudron.

[Emilien-Lambert]

Hello everyone,

I'd like some help / explanation about connecting an NFS share with Cloudron.

I have a raspberry with ip 192.168.1.63 on my home LAN.
On Cloudron I installed OpenVPN and created an .ovnp file, then put it in the raspberry. Now the raspberry is connected with ip 10.8.0.6.

I created a /mnt/yotta folder on my raspberry and modified the /etc/exports file with this:

/mnt/yotta IP_OF_MY_CLOUDRON(rw,sync,no_subtree_check)
/mnt/yotta 192.168.1.0/24(rw,sync,no_subtree_check)

On my Mac, if I do

mount -t nfs -v 192.168.1.63:/mnt/yotta ~/nfs/rpi_test/

My mac mini connects well and everything works.

Now on the Cloudron interface I go to Volumes then Add Volumes

The connection doesn't work. I've looked everywhere and can't find what's wrong. If someone can explain to me what I'm doing wrong, it would be very simple. Thanks in advance.

@Emilien-Lambert Have you already tried manually mounting (via ssh) on Clourdon like you did on your Mac? Sometimes it's hard to parse the error from systemd-mount output. You can check journalctl -fa or dmesg for more raw mount errors.

Thank you for your help

I've just tried, on my Cloudron server I did :

mount -t nfs -v 192.168.1.63:/mnt/yotta ~/test/
mount.nfs: failed to apply fstab options

but with sudo return :

sudo mount -t nfs -v 192.168.1.63:/mnt/yotta ~/test/ 
mount.nfs: timeout set for Wed Nov  8 15:58:10 2023
mount.nfs: trying text-based options 'vers=4.2,addr=192.168.1.63,clientaddr=91.134.91.178'

And the terminal stays like that, nothing else happens.

If I do journalctl -fa or dmesg

for journalctl -fa :

mount -t nfs -v 192.168.1.63:/mnt/yotta ~/test/
mount.nfs: failed to apply fstab options

journalctl -fa

for dmesg I have a very long :

Also something I don't understand is that my raspberry is well connected and the cloudron OpenVPN application detects the raspberry well. But if I connect with ssh to the Cloudron server and ping 192.168.1.36 local ip of the pi or 10.8.0.6 ip of openVPN

No matter, the ping doesn't work. It's weird, the vpn should make the server see the raspberry on the network?

@Emilien-Lambert said in Share a ssd from a raspberry on my local network and mount it on Cloudron.:

sudo mount -t nfs -v 192.168.1.63:/mnt/yotta ~/test/
mount.nfs: timeout set for Wed Nov 8 15:58:10 2023
mount.nfs: trying text-based options 'vers=4.2,addr=192.168.1.63,clientaddr=91.134.91.178'

Ah, there is a network connectivity issue here.

So, the OpenVPN app on Cloudron does not behave the way you think. The app is standalone and you can make the PI use the OpenVPN (as you already did).

But the Cloudron server itself is not part of the VPN This means that it cannot reach the pi . There is a feature request to make Cloudron part of a VPN, but we have not implemented this yet.

[Emilien-Lambert]

OK, I understand better, thanks for the explanation. Is there a way to connect an ssd from my house to the server?

I'd say I could install a vpn on the server via ssh (WireGuard) and therefore not use Cloudron's openVPN application. But I don't know if this would have any impact on Cloudron's operation?

[girish]

@Emilien-Lambert generally, we don't recommend installing other software alongside Cloudron since future update might break things. But if you are aware of this "warning", go ahead. It shouldn't interfere with Cloudron.

[Emilien-Lambert]

I'll give it a try. Thank you very much for your help and explanations.
