Enabled maintenance mode for backup, disabled & now get error about permissions

ℹ️ Support

Hi i have just tried using RPI-CLONE to take a backup of the disk attached and seemed to work OK…
then i thought id be smart and put nextcloudn into maintenance mode & stopping apache & mysql
sudo php /var/www/nextcloud/occ maintenance:mode --on
sudo systemctl stop apache2
sudo systemctl stop mariadb

backup ran again, seemingly OK

then restarted sql/apache & turned maintenance mode off
sudo systemctl start mariadb
sudo systemctl restart apache2
sudo php /var/www/nextcloud/occ maintenance:mode --off

but now i get when trying to login

Error

  • Cannot write into “config” directory!This can usually be fixed by giving the webserver write access to the config directory. But, if you prefer to keep config.php file read only, set the option “config_is_read_only” to true in it. See https://docs.nextcloud.com/server/23/go.php?to=admin-config

is there something else i need to do to get it out of maintenenace mode?
(i have tried enabling/disabling again & restarting)

Thanks!

ah i seem to of fixed it by running

sudo chmod 660 /var/www/nextcloud/config/config.php
sudo chown root:www-data /var/www/nextcloud/config/config.php

question… should this need to be ran after going in and out of maintenance mode or is it a bug?

thanks!

Someone/thing changed the permissions. Try putting it in maintenance mode and then recheck permissions on the config.php file. Then take it out of maintenance and check again. Perhaps for some reason the cloning script you are using is doing it or just user error?

ls -l /var/www/nextcloud/config/

hi thanks for the reply…
I’ve just done the same again without the rpi-clone

maintenance mode on
stop Apache
stop mysql

start mysql
start Apache
maintenance mode off

same error, I had to do the permissions again on the config, so must be some oddness with maintenance mode, at least I know what to if I need to clone the drive again.

cheers

try this instead:

Turn on maintenance mode. Then check the permissions on /var/www/nextcloud/config/config.php

See if it changed. If it didnt then do the same with apache. If it does then an idea would be to check your .htaccess file to see if something is not right there.

To my understanding, You do not need to stop apache or mysql in order to run a backup.

Thanks again, its definatley the maintenance mode on, then off that triggers this, ive just done

I have two NC systems setup. One is production for a client and the other one is my test bed on a VM. In both of them the config.php file is:

-rw-r----- 1 www-data www-data 1370 Jan 12 17:21 config.php

I run maintence with the command:

sudo -u www-data php --define apc.enable_cli=1 /var/www/nextcloud/occ maintenance:mode --on

Might try that.

EDIT: --define is for caching with APC. If you do not have it then just omit the --define statement.

I guess coffee412 is right. Sounds good to run the occ commands in the usercontext of www-data and not as root like you tried before.
