if you're looking to run your app in a server farm for load balancing or redundancy, you have to ensure your uploads folder is common to all your servers
for example, we have 2 load balancers, and 5 vm servers in a web farm format, all the server instances have the apps upload folder mapped to our nas. or you can do this with just one server as well.
you can easily accomplish this, by the following command.
ensure you are in your apps root folder
run the command:
mount -t nfs IP_ADDRESS:myNASvolume/uploads ./uploadsto verify if the mount took, do a df -h
you should see your uploads folder pointed to the nas
192.168.0.236:/volume1/uploads 11T 323G 11T 4% /srv/www/htdocs/MYAPP/uploadsif it didn't work, you will see your uploads folder as normally displayed in a linux format
drwxr-xr-x 1 wwwrun www 70 Sep 11 19:19 uploadsyou'll need to perform this as root or sudo.
in order to make this mount automatically after reboots, check with your linux version on how to and where to add the mount command (usually fstabs)
