Use second hard disk in samba network for storage

nanooker · February 8, 2021, 4:20pm

Dietpi is running on raspberrypi 3B+ with ssd data storage in smb network. This works fine.
Now I have connected a second usb hard drive to the pi.
What is the process that this disk also works as storage and is recognized on the network.
The hard drive is visible in Dietpi-config and is recognized, but it does not appear in my network.
Despite mount, unmount I can not get it to work.
Could someone help me? Thanks

Hi,

pls can you share your smb.conf file as well as lsblk -o name,fstype,label,size,ro,type,mountpoint

that the new drive is not shared via SAMBA is working as expected because it is not configured to be shared

At the moment you are sharing everything below directory /mnt/dietpi_userdata. But your new drive is mounted to a different place /mnt/d7afc196-c7ba-4af5-bb7d-56045bb9642a. Therefore it is not visible on SAMBA. Basically you would have 3 options

mount your new HDD on a mountpoint below /mnt/dietpi_userdata like /mnt/dietpi_userdata/HDD2
change the SAMAB export to /mnt. This will share everything below /mnt, including your new drive
create a 2nd SAMBA export for /mnt/d7afc196-c7ba-4af5-bb7d-56045bb9642a. This would need to be mapped as an additional drive on the client side

Hello,
first of all thank you!!
I have now chosen the first option. Now I see the hard disk. There are two folders “Documents and Lost+found”.
But I can not access them. No permission!
You write “change the samba export to mnt”. I don’t know how to do that??

Joulinar · February 9, 2021, 12:07pm

ok let’s check permission ls -la /mnt/dietpi_userdata/HDD2

nanooker · February 9, 2021, 12:20pm

insgesamt 28
drwxr-xr-x 4 root root 4096 Feb 9 10:43 .
drwxrwxr-x 8 dietpi dietpi 4096 Feb 9 13:12 …
drwxr-xr-x 3 root root 4096 Feb 9 10:43 dietpi_userdata
drwx------ 2 root root 16384 Feb 8 15:11 lost+found

Joulinar · February 9, 2021, 12:27pm

ok the folder is owned by user root. But access on SAMBA is done by user dietpi. Therefore is fine to have permission issues

drwxr-xr-x 3 root root 4096 Feb 9 10:43 dietpi_userdata

you could try changing whole content of your HDD to belong to user dietpi

chmod -R dietpi:dietpi /mnt/dietpi_userdata/HDD2

nanooker · February 9, 2021, 12:33pm

Joulinar · February 9, 2021, 1:10pm

ah sorry my fault

chown -R dietpi:dietpi /mnt/dietpi_userdata/HDD2

nanooker · February 9, 2021, 2:42pm

Wonderful works perfectly. Hopefully I still know that next time or a possible reinstallation. I guess it can not be simpler?
Thank you very much for the help. I would never have managed alone.

Joulinar · February 9, 2021, 3:05pm

well it’s already quite simple

add drive to correct place
use correct permissions

nanooker · February 9, 2021, 4:45pm

Thanks again!
Do I need to mark the post as done where?
And where should I send the box of wine / beer?

Joulinar · February 9, 2021, 7:17pm

I marked it as solved already.

Sorry I have to ask again
I wanted to create a backup on the second hard drive.
This apparently does not work because of “mnt/userdata”.

Joulinar · February 9, 2021, 7:25pm

pls can you be a little bit more specific what you have tried and what was the error you faced.
