n/a
- PHP version (e.g, 8.3):
8.4.25
- Is this the first time you’ve seen this error? (Yes / No):

Summary of the issue you are facing:
My host recently rebooted after installing Ubuntu updates. Afterwards, I realized the NFS share from my NAS did not persist through the reboot. I remounted the disk and checked the paths and restarted the docker containers and everything seems to be up and running fine; however, I cannot open any files.
When I run the command
“sudo docker exect -u www-data nextcloud-aio-nextcloud php occ files:scan --all”
It returns the following
“Starting scan for user 1 out of 3 (admin)
Path not found: User folder /mnt/ncdata/admin/files exists in cache but not on disk”
(this repeats for the other 2 users)
I confirmed the mount is up and running using ls and dh. I confirmed the paths do in fact exist (there’s nothing wrong with the NFS share or the files, everything does actually exist). Seems Nextcloud simply can’t “see” them? I searched through and found others with similar problems but they either don’t have a fix or their fix did not work for me.
Steps to replicate it (hint: details matter!):
- Not sure how to go about replicating this. The error persists through reboots and restarting containers. I can simply run the php occ files:scan --all command to see it again.
Log entries
Nextcloud
Please provide the log entries from your Nextcloud log that are generated during the time of problem (via the Copy raw option from Administration settings->Logging screen or from your nextcloud.log located in your data directory). Feel free to use a pastebin/gist service if necessary.
This is what the log shows when I try to access a file
{"reqId":"vJP9CmQbfHWv0hLLkFsx","level":2,"time":"2026-09-25T12:46:37+00:00","remoteAddr":"172.18.10.1","user":"--","app":"PHP","method":"GET","url":"/apps/richdocuments/settings/userconfig/Anfev0vKNnFmy3Io5k5FwkAn8TbF7C7G/template/Yellow%20idea.odp?identifier=176","scriptName":"/index.php","message":"file_get_contents(/mnt/ncdata/jason/files/Templates/Yellow idea.odp): Failed to open stream: No such file or directory at /var/www/html/lib/private/Files/Storage/Local.php#318","userAgent":"COOLWSD HTTP Agent 26.04.3.2","version":"34.0.4.1","data":{"app":"PHP"},"id":"6ab6762f338fa"}
Web Browser
If the problem is related to the Web interface, open your browser inspector Console and Network tabs while refreshing (reloading) and reproducing the problem. Provide any relevant output/errors here that appear.
Problem exists no matter where I try to access files from
Web server / Reverse Proxy
The output of your Apache/nginx/system log in /var/log/____:
Unsure where to find this separate log specifically, my apache container's /var/log folder contains a single apk.log file.
Configuration
Nextcloud
The output of occ config:list system or similar is best, but, if not possible, the contents of your config.php file from /path/to/nextcloud is fine (make sure to remove any identifiable information!):
