I am running Moodle 3.5 on a two node F5 load balanced Windows Server / IIS environment for 79k users. It uses a Isilon NAS share for Moodledata. I just noticed the upload_tmp_dir and sys_temp_dir settings in the php.ini file and I was wondering how those settings should be configured?
Should they each point to a shared temp folder on the Isilon NAS so that each of the two server nodes writes to the same folder, or should they each point to a local folder (e.g. C:\Temp) on each of the server nodes so that each node has it's own Temp folder?
In other words, do upload_tmp_dir and sys_temp_dir each require a shared folder?
