Greetings!
So here is TL;DR and more details below if needed: If my folder or drive with all my Movies and TV Shows is read only, do I loose any functionality beside the option to delete media content from within the plex interface. For example Analyze and Optimize features, downloading movie information from internet etc. Any other folders are read/write accessible except the one with all the multimedia content.
Long story is that currently PMS is installed in LXC container running on hypervisor and media content is connected to the container via NFS share provided by a VM with Rockstor (a NAS system) installed in it. This works fine and NFS share is read/write as well however this setup is running suboptimal due to the fact it has to transfer data over the network even when both PMS container and VM are located on same machine so it does raise I/O delay, generates 3x the network traffic and in general, uses slightly more system resources than if I had PMS as Rockstor addon within the same VM. I did play with loop device which mounts Rockstor main partition which later on, can be provided to the LXC container but while testing with that there were multiple issues including the fact that I got the partition corrupted. Basically as of right now, if I want to avoid the NFS share and the extra network traffic I can mount the VM’s partition with the media as read-only just to make sure nothing gets corrupted again. There are other options I’m also looking at but as of now, thats the only option I have besides the NFS share.
