Possible duplicate #39851 |
indeed |
Yes, that sounds like a duplicate. In the provided examples two characters are removed from the files names too. |

Bug description
At first I want to mention that I’m using Nextcloud for years now without having major issues with my configuration and installation.
End of September I decided to upgrade my server from Nextcloud 26.0.7 to 27.1.1. The installation itself worked without any issue but after a while I noticed that the Notes app caused errors because it couldn’t handle sub folders correctly anymore. Synchronization errors reported by the Nextcloud app pointed me to the issue. I checked the directory and file names using the web GUI and found-out, that it had been modified somehow and didn't look like the existing ones on the hard disk anymore. Due to the fact that I’m not using the Notes app very often and I couldn't find a pattern on a first glance, I decided to delete all sub folder below the Notes directory to get rid of the errors and wanted to wait for a new Notes app release. (It might be worth to know that the Notes folders is located on an external storage, which is being mounted using WebDAV.)
This week I’ve upgrade the server to Nextcloud 27.1.2 and again everything looked fine and I was able to use all functions as before. Yesterday I wanted to lookup some files and navigated to a sub folder, located on an external storage. Surprisingly all files and folders in that subdirectory were shown without the leading two characters of its names. It looks like something has corrupted the directory tree somehow, but other directories with sub folders in it, which exist in parallel of this one, are still being displayed correctly.
I tried to rescan the subdirectory by executing
"./occ files:scan <user> -p /<user>/files/folder"but the command shows invalid file names too.I’ve also tried to access Nextcloud using a different web browser or the Nextcloud app, but all are showing the corrupted files and directory names.
These are the names of the files and directories as they are shown in the web GUI:
These are the names of the files and directories as they exist on the hard disk:
eCards → CueCards
gene Musik → Eigene Musik
ergen → Juergen
Steps to reproduce
FYI, the sub folders name below "Dateien" is "CueCards" but as it can be seen from the log file, "/Dateien/eCards" are found and displayed.

Related log line in Apache access log
Any ideas how this issue can be resolved are hightly appreciated.
I've just scanned the directories of an other user using
"occ files:scan"and have seen the same issue. The first two characters of files in a sub directory are not shown anymore although they exist on the hard disk. It seems as if a general issue with the files scanning exists?!Expected behavior
All file and directory names should be shown with the correct names so that it matches the existing file structure on the hard disk.
