Wordpress Multisite using block-storage for /uploads

WordPress Block Storage

I have my Wordpress multisite installed in /var/www/example.com/u/
I created a block-storage called storage and it is mounted under /mnt/storage/, this contains a folder called /uploads.
In my Wordpress wp-config.php file I have this define('UPLOADS', '../../../../mnt/storage/uploads');
Which means the new upload folder is /mnt/storage/uploads

The owner is www-data:www-data and permissions is 0755 for /storage

The problem is that all my sites uploaded images and videos are broken. I also tried to upload a new image on one of the sites, and I can see it being uploaded under sites and the correct site id. But the image is not shown in Wordpress, neither in the media library or when I attach it to the site. So I cannot view the image at all.

Isn’t it enough to change this setting in wp-config.php? Do I have to do anything else to make it work?

I would recommend first copying your current uploads folder to your new location:

cp -r /var/www/example.com/u/wp-content/uploads/* /mnt/storage/uploads

That way you would make sure that your existing images are also present in your new uploads directory.

Also, I would suggest keeping your new uploads folder within your document root. So either mount the block storage somehere in: /var/www/example.com/u/ or create a symlink for /mnt/storage/uploads to /var/www/example.com/u/uploads for example.

Here’s an example on how to create the symlink:

ln -s /mnt/storage/uploads /var/www/example.com/u/uploads

Then update the UPLOAD path in your wp-config file to /var/www/example.com/u/uploads. This way your images would be available via http.

Let me know how it goes.

  • Thanks, symlink solved the issue!

    • No problem at all! I’m happy to hear that it is working that way!

      By the way, another way to solve this would be to mount the storage to /var/www/example.com/u/uploads directly. That way you would not have to use the symlink.
