I just set up my unRAID rig last night and so far I am very impressed. I was able to install few plugins including Mysql which I use to sync my XBMC library and also Plex, which is totally new to me. My set up is 1TB Parity drive, 1TB + 4x750Gb drives for storage, and then I added a 160Gb laptop drive for cache. I am actually confused with the way the cache drive works. So...
Question 1: I had unclean shutdown and my parity re-check is going right now, showing estimated speed 22.3 MB/sec. I believe it was the same before I added the cache drive so I don't see any gains I think. Is that normal and what is the point of having the cache drive?
Question 2: Currently I have Mysql and Plex installed in /mnt/cache/unRAID_Apps/ folder. I am concerned because Plex has been scanning my library all day and its not even half-way done with it. Would that data that is currently on the cache drive be moved on one of the disks later, or I need to put the plugins to store on a disk, not the cache? I am trying to avoid going through that massive scan again and store the library in a permanent location.
Question 3: Should I install any plugins on the cache drive directly or put on one of the disks and set the share to use cache?
Question 4: Is there a way for unRAID to automatically stop Mysql, Plex and Dropbox before shutdown/reboot? Otherwise the system hangs and rarely shuts down the way it should.
Thanks a bunch for shedding some light to a newbie
