Hello everyone,
I have some issue for setting up my external storage. I tried throught the NextcloudPi Wizard, but I get this error after clicking on the “Move data to USB” :
[ nc-automount ] (Sun Sep 25 18:58:17 BST 2022)
automount enabled
[ nc-datadir ] (Sun Sep 25 18:58:24 BST 2022)
Nextcloud is in maintenance mode, hence the database isn’t accessible.
Cannot perform any command except ‘maintenance:mode --off’

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/24/go.php?to=admin-dir_permissions
An unhandled exception has been thrown:

Everything worked find during the installation until here.
I’m a bit lost ? someone can help me ?
Best regards,
It doesn’t have permissions to write on your external drive.
sudo chown -R www-data:www-data /media/myCloudDrive
Should fix it, unless you’re using the wrong filesystem/partitioning on the drive which doesn’t support Linux permissions system
If you’re using a Raspberry Pi 4, you can boot directly from the external drive instead, saving you the hassle of dealing with the permissions. Just need to change the boot order in raspi-config and install directly on the external drive instead
Hello, thanks for answering so quickly !
Thanks for your answer. I finally fixed my issue changing direct config.php, I replaced /var/www/nextcloud/data for /media/myCloudDrive/ncdata/data. Same in php.ini.
It did work, BUT I now can’t, throught NextcloudPi wizard setup fail2ban. I got this message :

I tried your command, but like this :
sudo chown -R www-data:www-data /var/www/nextcloud
And fail2ban was able to write !
Hope I didn’t make anything wrong !

No, you did the right thing 
Since you changed your data directory, to change the command was the right choice
