Hi all
Ive been trying to get NextcloudPi running stable on a Raspberry Pi 4 Model B Rev 1.2 .
A couple of days a week it crashes and I get the message "Your data directory is invalid. Make sure you have the “.ocdata” file in the main directory of your data.
Unable to create “data” directory.".
Nextcloud version 25.0.3
Operating system and version Linux 6.1.21-v8+ aarch64
Apache or nginx version Unkown, how do I find that out?
PHP version 8.1.18
The issue you are facing: Get the error message "“Your data directory is invalid. Make sure you have the “.ocdata” file in the main directory of your data.”
Is this the first time you’ve seen this error? (Y/N):N, happens a couple of times a week, usually every time i add more files to it.
Steps to replicate it:
- Just wait and it will happen

Output errors in nextcloud.log in /var/www/ or as admin user in top right menu, filtering for errors. Use a pastebin service if necessary.

Hi,
let’s check off some easy boxes first:
1 Check that the user running Nextcloud has read and write permissions to the data directory.
ls -la in the directory containing the data directory and verify that the owner and group permissions are set correctly.
2 Make sure that the disk space on the Raspberry Pi is not full.
3 This is probably not the case, but with an old Pi still possible: Check the system for file system errors run the command sudo fsck /dev/sda1 to check the file system for errors.
Cheers
Thanks for reaching out but i need more help :).
I have more or less no experience in Linux.
I cant even figure out how to navigate to my external USB harddrive where all data is stored.
I am willing to learn but maybe in baby steps.
-
How do I change the drive to my USB, and how can I loose write permissions to that randomly?
-
The Raspberry has a 32 gig SD card, root has 24 gig left so thats ok.
-
Its a Raspberry 4 so not an older verison.
And now it crashed again with the same error.
Is it actualy possible to have nextcloud running stable?
To answer your question: Yes it is.
To be honest it will require some knowledge in Linux and all that stuff. You will learn a lot in the beginning with every weird problem you will have.
You tagged your post with “ncp” which means you use nextcloudpi for your device. All docs for this project are at docs.nextcloudpi.com. it will help a lot to read a few articles there.

I have found no information regarding my problem, “Your data directory is invalid. Make sure you have the “.ocdata” file in the main directory of your data”
Can you point me in the right direction? Since it works for a while and the suddenly doesnt work it must be something else than write permissions since they dont change by them self? A file doesnt disappear either and the reappear when i reboot the pi.
Best option to start is to check the logs. Please ssh into your machine and type the command ncp-report . copy all the data and post it here
Hi again.
I uploaded some stuff earlier today and after that it crashed again. It seems like it looses the connection to my USB drive for some reason?

Your data directory is invalid.
Ensure there is a file called ".ocdata" in the root of the data directory.
Cannot create "data" directory.
This can usually be fixed by giving the web server write access to the root directory. See https://docs.nextcloud.com/server/25/go.php?to=admin-dir_permissions

Looks like the drive is not mounting correctly, maybe the drive or it’s power source are starting to fail.
I’d would likely try to mount it my (Linux) PC to investigate.
Reading this also makes me realize, that you might want to check the power supply of your Pi. Is it powered by the needed voltage? Not enough and it might just kick your USB drive out of the loop for a moment.
I myself do that from time to time, out of bad habit, and just throw an old and skimpy smartphone charger at my Pi, which is not smart of me.
I have power supply that is up to spec but I will try another one just to be sure.
Good input, thanks.
Its a brand new drive.
Can there be some sort of power save on the drive?
I tried to unplug and replug the drive last time but nextcloud didnt find the files.
Is there some command I can use to try to re mount the drive?
It also only happens after I upload new files

Not a good idea, rather use [this howto] to mount a drive permanently (Mounting an external drive using UUID and fstab | Linux admin junior)
Power save, could slow things down, but should just power back on when uploading files.
To check if and where drives are mounted I use:
sudo df -hT
In Linux to mount a drive one uses
sudo mount /dev/sda1 /media/drivename
But you enabled automount so should not need to manually mount unless you add more drives to your system.
Yesterday I uploaded som more date and after some time teh server crashed again with teh same error.
The command sudo df -hT gave me the following result:

My external drive isnt there, it is 14TB
After a reboot it looked like this

Son now the external drive is there. So for some reason the external drive is dropped after new data is added to nextcloud
I would look at the system logs in /var/log just after the event.
-rw-r----- 1 root adm 2,1M May 17 10:34 syslog
-rw-r----- 1 root adm 1,5M May 17 10:34 messages
-rw-r----- 1 root adm 1,5M May 17 10:34 kern.log
Run from terminal:
sudo cat /var/log/syslog
And look for error messages
I guess its better to do this after a crash but now when everything is fine i found one error message:
Transfer event TRB DMA ptr not part of current TD ep_index 3 comp_code 1
Didnt take much time for another crash, this time witk no activity in Nextcloud at all
Log here
So it crashed again tonight.
I tried “sudo mount /dev/sda1/media/myCloudDrive”
And got can’t find in /etc/fstab.
How is that possible?
May we have a cat of your fstab file?
cat /etc/fstab
