Permissions Error occurring ~one week after the last server reboot

ℹ️ Support
1

Nextcloud version : 24.0.3.2
Operating system and version : Ubuntu 22.04.1 LTS
Apache or nginx version : Apache/2.4.52 (Ubuntu)
PHP version : PHP 8.1.11
LAMP Stack and nothing else is installed other than Nextcloud on the server.

Hello everyone,

After i use Nextcloud for about a week i get the following message:

“Error:
Your data directory is not writable.
Permissions can usually be fixed by giving the web server write access to the root directory. See Introduction — Nextcloud latest Administration Manual latest documentation”

The Error goes away if i restart the server and then it appears again about a week later. I didn’t notice that it appears after a specific usage but more or less a week after the last reboot.

Is this the first time you’ve seen this error? (Y/N): No It occurs since i installed Nextcloud

Steps to replicate it:

  1. I just use Nextcloud normally for about a week.

I don’t know what to look for in the nextcloud.log

Thank you for your efforts!

Please check healthiness of your filesystem.

Could be a connection issue (defective data cable), a power issue (the drive is receiving insufficient or unstable power), a driver issue (less likely nowdays), or in the worst case, a dying drive.

is this an SSD or a mechanical drive?

How ist it connected? external (USB) or internal (SATA)?

Is it connected directly to the motherboard or via a USB hub, or if internal, via some RAID / JBOD card?

4

It is one SSD connected by SATA directly to the motherboard (no RAID / JBOD)

The Mini PC-Server is running for 2 Months and the SSD (Western Digital RED SA500) is also new.

How to do this ?

This issue is unrelated to Nextcloud and so I recommend you to search the internet about how to check ext4 filesystem on ubuntu linux.

First thing I would try is replacing the SATA cable. A defective cable can definitely cause exactly the issue you are experiencing…

Other possible reasons that come to mind, as already mentioned:

  • The SSD itself. Even new devices can be defective. RMA it, if replacing the cable doesn’t help.

  • some issue with the power delivery, either caused by the power supply or the motherboard, although these is rather unlikely with an SSD…

  • Chipset respectively SATA controller or incompatibility with Ubuntu 22.04, also rather unlikely, unless the PC is brand new maybe…

Also @rakekniven is right, the issue is not related to Nextcloud, although I don’t think it’s an issue with the filesystem directly. But you should of course not use the server productively, unless you solved the issue. And backup all your important data before you do any further experiments…

Good luck.
