Could not create folder

ℹ️ Support
1

I setup a new nextcloud manually following the guide from LearnLinuxTV.
The way I set it up:

  • On an Debian 12 LXC on Proxmox
  • Nextcloud version: 27.0.1
  • PHP version: 8.2
  • MariaDB: 10.11.3-MariaDB-1
  • Redis: 7.0.11

During the setup I specify my data directory as: /mnt/matahari/data
Everything seems to run OK, but I can’t create folder or file.

I check the permissions like the followings:

matahari@nextcloud:~$ df -h

and here is from my nextcloud logging:

I don’t know what to do and I need help to fix this. I have searched in this forum and tried many suggestions (chmod 755 on data directory, etc) but to no success.
thank you

Based on that log entry your Redis server is not configured properly. Either the parameters to connect to it from NC (i.e. in your config.php) are wrong or your Redis server isn’t running.

I’m not familiar with the third-party guide you used, but assuming it’s a reasonable guide I would review any sections it has that reference Redis.

Thank you!
I finally figure it out… apparently… my config.php points to a non-existent redis folder.

'memcache.local' => '\\OC\\Memcache\\APCu',
  'filelocking.enabled' => true,
  'memcache.locking' => '\OC\Memcache\Redis',
  'redis' => array(
     'host' => '/var/run/redis/redis.sock',
     'port' => 0,
     'timeout' => 0.0,
      ),

it should be

'host' => '/var/run/redis/redis-server.sock',
