External Storage not syncing correctly

ℹ️ Support
1

Dear community,
some weeks ago I installed NC 26.0.1. Since then I facing various Issues. The biggest “pain in the ass” is: external storages are not synchronized correctly. NC synchronises randomly some files and some not. Nor the cloud itself nor the clients (for Windows + Android) show the complete content of the connected folders. The storage is connected via SMB/CIFS. It all worked fine with NC 24.

Any idea how to fix the issue?

Details:

Nextcloud version: 26.0.1
Operating system and version : 22.04 LTS
nginx version: 1.18.0
PHP version: 8.2.7
mariaDB Version: 10.6.12
smbd Version: 4.15.13
External Storage support Version: 1.18.0

The issue you are facing:

Is this the first time you’ve seen this error? Yes:

Steps to replicate it: The Issue is random, sometimes content is shown, sometimes not. After one failed trail of syncing the content is never shown anymore - it´s not deleted, but noted as 0B content.

For your first issue, are you adding files to the External Mount outside of NC?

For the second issue, that looks like a bug. It may be worth reporting:

However troubleshooting SMB issues is challenging because there are a lot of dependencies.

It looks like you’re using the smbclient binary rather than the recommended libsmbclient-php. That isn’t necessarily the source of your issues though - and it should work with either way. The main downside to the binary is lower performance.

HI jtr,
thanks for the tipp. The first link resolved the problem. I installed the libsmbclient-php with:
apt-get install php-smbclient
and removed the other smbclient completely with:
apt-get purge --auto-remove smbclient
rebooted and now all works fine
Thanks!!!
