Hi, I have a raspberry pi 4 with a NCP image installed and nothing else. All automatic updates are enabled. It’s been working fine until day before yesterday. I’m getting a ‘internal server error’ when I go to the login site. Nextcloud check gives an error (datadir doesn’t exist) and after some time MariaDB goes down too (strangely not always…). I found different and dated solutions in the forum but I didn’t wanted to apply them blindly, that’s why I opened a new topic. I’m sorry if I bloated the forum… | NextCloudPi version | v1.20.1 | | --- | --- | | NextCloudPi image | NextCloudPi\_07-21-19 | | distribution | Raspbian GNU/Linux 10 \n \l | | automount | yes | | USB devices | none | | datadir | /media/USBdrive/ncdata (doesn’t exist) | | rootfs usage | 2.5G/29G | | swapfile | /var/swap | | dbdir | /var/lib/mysql | | Nextcloud check | error | | HTTPD service | up | | PHP service | up | | MariaDB service | up | | Redis service | up | | Postfix service | up | | internet check | ok | | port check 80 | open | | port check 443 | open | | IP | 192.168.178.148 | | gateway | 192.168.178.1 | | interface | eth0 | | certificates | none | | NAT loopback | no | | uptime | 1:52 | I appreciate if someone could help. ---

Your USBdrive seems to be disconnected! Did you try to connect a second drive? And also can you access your pi via ssh? If so share output of: > ls -lh /media/ ---

Thanks for the reply mate. I did have a second usbdrive for the database backups from beginning on, never had any problem with it. I just took it out and rebooted to try, it worked for a minute and then gave the same error again. I can access the device via ssh and NCP webui… ‘ls -lh /media/’ output is ‘total 0’ . Here is the ‘sudo ncp-report’ output if it helps: > **NextCloudPi diagnostics** > > ```auto > > PHP Warning: fileperms(): stat failed for /media/USBdrive/ncdata/nextcloud.log in /var/www/nextcloud/lib/private/Log/File.php on line 85 > {"reqId":"JXNdTLXSIZXJePESaxv0","level":3,"time":"2020-01-25T19:15:02+00:00","remoteAddr":"","user":"--","app":"PHP","method":"","url":"--","message":"fileperms(): stat failed for \/media\/USBdrive\/ncdata\/nextcloud.log at \/var\/www\/nextcloud\/lib\/private\/Log\/File.php#85","userAgent":"--","version":"17.0.2.1"} > {"reqId":"JXNdTLXSIZXJePESaxv0","level":2,"time":"2020-01-25T19:15:02+00:00","remoteAddr":"","user":"--","app":"no app in context","method":"","url":"--","message":"Temporary directory \/media\/USBdrive\/ncdata\/tmp is not present or writable","userAgent":"--","version":"17.0.2.1"} > PHP Warning: fileperms(): stat failed for /media/USBdrive/ncdata/nextcloud.log in /var/www/nextcloud/lib/private/Log/File.php on line 85 > {"reqId":"JXNdTLXSIZXJePESaxv0","level":3,"time":"2020-01-25T19:15:03+00:00","remoteAddr":"","user":"--","app":"PHP","method":"","url":"--","message":"file_get_contents(\/media\/USBdrive\/ncdata\/news\/config\/config.ini): failed to open stream: No such file or directory at \/var\/www\/nextcloud\/lib\/private\/Files\/Storage\/Local.php#217","userAgent":"--","version":"17.0.2.1"} > PHP Warning: fileperms(): stat failed for /media/USBdrive/ncdata/nextcloud.log in /var/www/nextcloud/lib/private/Log/File.php on line 85 > {"reqId":"JXNdTLXSIZXJePESaxv0","level":3,"time":"2020-01-25T19:15:03+00:00","remoteAddr":"","user":"--","app":"PHP","method":"","url":"--","message":"fileperms(): stat failed for \/media\/USBdrive\/ncdata\/nextcloud.log at \/var\/www\/nextcloud\/lib\/private\/Log\/File.php#85","userAgent":"--","version":"17.0.2.1"} > {"reqId":"JXNdTLXSIZXJePESaxv0","level":2,"time":"2020-01-25T19:15:03+00:00","remoteAddr":"","user":"--","app":"news","method":"","url":"--","message":"Configuration invalid.

What is the output of > sudo ls -lh /var/www/nextcloud/ If your data directory is still in there, edit the config.php datadir value to point to it. If you did not use nc-automount, how and where did you mount your external drive? ---

It probably was not removed safely or the drive is corrupt, you’ll have to try to connect it to another pc to try to fix it. On Linux I use **[fsck](https://www.tecmint.com/fsck-repair-file-system-errors-in-linux/)** ---

Ok, I’ll try. I bought a new drive just in case. If I copy paste the folder from the old drive to the new one, would it work? Or do I have to sync both drives somehow… ? Any with which tool would you do it on linux? Thanks alot for your help mate! ---

Hi @OliverV fsck didn’t work because of the btrfs partition. I did a check and repair in gparted. And then cloned the old drive to the new one with ‘dd’ Plugged the new drive to the raspi, it worked for 10 minutes, after it started to give the same ‘Nextcloud check error’ I’m at a lost here… ---

there is [btrfs-check](https://btrfs.wiki.kernel.org/index.php/Manpage/btrfs-check), did you try it? ---

I did, no errors were found… It’s like the USB devices are safely removed after being automounted… I tried with a USB stick as well… lsusb shows nothing… I have a instance backup, if i flash the NCP image to the sdcard again and restore from backup would it help? And how should I proceed with the data dir then? ---

Clearly my raspberry pi’s USB doesn’t work as expected anymore. I tried with usb stick as well, it loses power sometime after plugging in. I contacted the warranty service, lets see what happens. I ordered a Rock64 as a replacement. Thanks for the suggestions! ---

Continuing the discussion from [[NCP] Nextcloud check error](https://help.nextcloud.com/t/ncp-nextcloud-check-error/69144): I am experiencing exactly the same issue. This happened after i installed the v1.20.7. Interestingly enough when typing in ls -lh /media/ during boot-up it appears as if the drive is being mounted. Once the NCP is fooly booted it disappears. ---

On Raspberry Pi 4? I’d first install another OS on a second sdcard and see if the problem persists… ---

Indeed the Raspberry Pi 4. I have tried exactly what you suggested. What I can report is that problem persists. I have tried it with three different drives, to ensure that it is not an issue caused by the HDD or SSD. What I have noticed though is that this is only caused by the USB 3 ports. There are absolutely no issues to report with the USB 2 ports. ---

I am having the same problem on a Raspberry Pi 4 using a USB 3 port. The “internal server error” occurred and MariaDB went down. I did a complete reinstall of the NCP image and less than a day later, I am getting the same error. Maria DB is still up, but I am now getting the “Nextcloud check error.” I will try it with a USB 2 port. EDIT: switching to a USB 2 port brought Nextcloud back up. I will report back if it goes down again. ---

I tried with USB 2 ports and had the same problem unfortunately. Contacted the warranty service where i bought the Pi4 to get it checked but if you guys are having the same problem, it might be an problem caused by an update… ---

After a day or so, my NCP/Nextcloud instance crashed again. This is after moving the external drive to a USB 2 port (on a Pi4). The first time this happened, I could not access Nextcloud, but could still access the NCP page (:4443). This time I cannot access either one. The Pi4 seems to be down entirely this time as I cannot ssh into it. I will reboot it and see how long it stays up. This issue started with the most recent update.
