It is very late: nearly 12:30am on Saturday. We are back from Beer and Beethoven. I will tell you all about that on Saturday.
Right now, though, I want to report that I have mostly vanquished the problem I was having with Plex on Thursday evening. Yay to me. I did some research today and found that the problem I had last night was pretty common. The easiest solution seemed to be to associate the external hard drives with a particular mount point on the server box; this mount point had to have the same name as I had given it in the fstab file also on the server box. Furthermore, the mountpoint had to have full read/write access, so the chmod 777 /media/labelname was very handy.
For some reason I do not understand, the NAS devices are not being found by Plex; just the two plain old external hard drives are located now. The good news is that Plex is downstairs furiously indexing some 1700 movies, and I am successfully running the Plex client on the Roku streaming stick. I even started to play something, and it worked very well.
The bad news, as I mentioned, is that the NAS devices cannot be found by Plex. And, the external hard drive I plugged into one of the NAS device's usb drive is nowhere to be found, either. I should be able to plug that external hard drive in an empty usb slot on the server box plus do the stuff I mentioned earlier, in order for the contents of that hard drive to be recognized by Plex.
That still leaves the NAS devices. If I can't figure it out, I will be only too happy to copy their contents to plain old external hard drives and do what I did earlier to make those be recognized.
So, this time last evening I was pretty frustrated, but I feel much better this evening. The battle has been mostly won with Plex, I had a good time at Beer and Beethoven, and I will relate a funny story about B&B on the morrow.
Right now, though, I have to get some shuteye. I must get up in just a few hours to do some overtime.
See you tomorrow.
