Cannot mount USB local drives

vale.maio2 · June 19, 2019, 5:10pm

Steps to reproduce

Login onto OC web configuration
Try to add local folder as external storage

Expected behaviour

Indicator for the external storage should go green.
I’m trying to add a local storage as external storage, after allowing local storage from the config.php. I can see the option in the Web UI but no matter what USB drive I select, I cannot see the indicator going green.
My server is just a laptop running Lubutnu 18.04.
I can access those USB drives from my Windows machine on the network by using Lubuntu SMB share.
When I add a test folder from within the installation disk (think /home/user/Music) I can access that folder in OwnCloud with no issue.
The USB drives are NTFS formatted and unfortunately cannot be formatted as they contains TBs of data.

Actual behaviour

Indicator for the external storage stays red, cannot see the content of the folders created

Forget about ownCloud for a moment, are you sure the USB drive is mounted properly in the FS and can access to it?
php code doesn’t seem to be able to access to that folder. Does the server have enough permissions to access to that folder?

If you can access to those files via SMB share, you can try to use the SMB connection in ownCloud instead of the local one.

This is the output of mount | column -t

Those are the 4 USB drives I’m trying to use in OC, all of them are NTFS. Do they look right? I wouldn’t be sure, sorry.
Regarding using them as SMB, although SMB share from Lubuntu to Windows works, it does not in OC. I treid with session credentials, with username and password, using different mount points. Still nada.
To be clear, as host I have the OC internal IP address (192.168.x.x), for share I tried /dev/sdb1,
/media/vale/SAMSUNG and \multimedia\Samsung (Windows share path), nothing in remote subfolder and WORKGROUP in domain.

If you want to access them through local storage, access to those locations (/media/vale/…) and make sure you can read any files inside it and check the file properties.

For SMB access, it might be better if you can show an screenshot of the configuration. You’re probably setting something wrong.

If you can try “multimedia” as host and “Samsung” as share (assuming that “multimedia” will be resolved properly). You can also try to use the ip address where the SMB shares are as host.
I’d recommend you to familiarize with smbclient, and check if you can access to those shares using smbclient.

I’ve tried both configurations, none of them worked so far. You can see from the screenshot attached bothconfigurations for Local and SMB. For SMB I also tried manually inputting the credentials, but it didn’t work.

For local storage, make sure the web server’s user (www-data / apache) can access to the folder without any problem. You might access to the folder, but maybe the web server can’t.

For SMB, the share is just “Samsung” in your case.

YES. Thank you so much. Although I still cannot access the folders on OC as a local share, I can now see them as SMB shares. Might not be very elegant but it works.
Thank you again.
