We have two Azure VM's - one running IIS and another running SQL. On the IIS VM we have mounted an Azure File Share. In the IIS site the physical path is UNC. On the surface the DNN site worked but then the purge module cache and dnn index service both gave IO errors and were failing. This caused problems with modules and we would have to clear the .net temp folder in the windows directory to fix issues.
The reason for disk storage is to facilitate a shared IIS config so we can setup a web farm later with a load balancer. Has anyone else experienced this issue?
