Hi there,
I hope someone can help me on this issue. As I still have the problem, that the data dir is reported not to be writable I did some additional research in the meantime and figured out there could be an issue with the php function ‘is_writable’. Obviously in some cases the function returns not writable even if this is not true. If I run the following script:
<?php
$dir = '/var/oc_data';
if (is_writable($dir)) {
echo $dir, ' is writable';
} else {
echo $dir, ' is NOT writable';
}
?>
it returns ‘NOT writable’.
Unfortunately I don’t understand which php scripts are used during update process which may use this function.
Any thoughts on that?
Thank you in advance for your help.
Steps to reproduce
- Prepare update as described under https://doc.owncloud.org/server/8.2/admin_manual/maintenance/manual_upgrade.html
- Start sudo -u www-data php occ upgrade
Expected behaviour
Update to new version should be done
Actual behaviour
Update hangs with:
Data directory (/var/oc_data) not writable by ownCloud
Permissions can usually be fixed by giving the webserver write access to the root directory.
Even switching of the maintenance mode is not possible and end up in the same error message.
file/directory permissions and ownership for /var/www/owncloud and the data directory as well have been set up as recommended in the owncloud documentation (strong permissions).
