Furthermore
While I had issues with bind-mounting the database and nextcloud on the iscsi mount before, this got resloved by changing the filesystem from xfs to ext4
I highly doubt that the is issue has something to do with the iscsi mount, but it shoudn’t be ruled out.
As shown in the compose file, I seperated the /var/www/html into 2 named volumes and 2 bind mounts.
The logs show that the error occurs in /var/www/html/lib/base.php which is located inside one of the named volumes.
- nc_settings:/var/www/html:rw
- /mnt/iscsi/nextcloud/apps:/var/www/html/custom_apps:rw
- nc_config:/var/www/html/config:rw
- /mnt/iscsi/nextcloud/data:/var/www/html/data:rw
While writing this I found an issue in my iscsi.conf file but it didn’t fix the isse at hand, I just made the containers autostart instead of manual.
Some speculation
Because I have an issue that I can’t log-in on a fresh install using the Firefox Web-browser and the nextcloud contacts app does not working in safari, I will speculate, that the issue has something to do with the apache2 server, hence after consulting if infact this could be the case. I would switch to the fpm package.
Edit/Update:
Looking into the code itself based on the error message.
Following function is related to the error.
//line 417
public static function setRequiredIniValues() {
@ini_set('default_charset', 'UTF-8');
@ini_set('gd.jpeg_ignore_warning', '1');
}
// User and Groups
//line 659
if (!$systemConfig->getValue("installed", false)) {
self::$server->getSession()->set('user_id', '');
}
//line 425
private static function sendSameSiteCookies() {
$cookieParams = session_get_cookie_params();
$secureCookie = ($cookieParams['secure'] === true) ? 'secure; ' : '';
$policies = [
'lax',
'strict',
];
//line 996
// Someone is logged in
if (\OC::$server->getUserSession()->isLoggedIn()) {
OC_App::loadApps();
OC_User::setupBackends();
OC_Util::setupFS();
header('Location: ' . \OC::$server->getURLGenerator()->linkToDefaultPageUrl());
} else {
// Not handled and not logged in
header('Location: ' . \OC::$server->getURLGenerator()->linkToRouteAbsolute('core.login.showLoginForm'));
}
Sadly I have no understanding of php code because I never worked with it.
