Thank you both for the help. I'm still a bit unsure after reading the manual but for now I'll take it for what it is. In the near future, I'll test that by manually forcing and array rebuild. Thanks

Yes, in a normal RAID setup, the data is spread/banded across the available drives and the damaged/missing pieces can be re-assembled. In UNRAID using the default High-Water method, currently all my data is on one disk (from what I can see). So if I lose that disk (say mechanical failure) how does UNRAID re-construct my files.

So, parity is a copy of all my data ? that's not my understanding on that concept.

I've been using UNRAID for about 2 months, for the moist part it works very well. I have 6 HDD's and an NVME stick in a QNAP TS-673a. HDD1 is for parity HDD2-5 is for the array (BTRFS) NVME is the cache I have a plex share on HDD1, excluding all other disks, and a documents share spread amongst the other four disks. Today, while trying to install Plex, I noticed that my documents share is only using the first disk (out of four) in the array ?? If I lose that drive I'm done ! Is there something I'm missing in my setup ? Thanks PS: Yes I have offline backups of my media and documents...

Yes the drives did spin down, it was not outside TrueNas but I forget how I set it up, it was a few years back. The drives only blink when they were accessed all of them as I did not have the ability to for example isolate the Plex media to one drive (really like that feature) and so when I play a movie the whole array spun up. Otherwise activity lights were on.

So I re-ran the diags and sure enough (if I'm looking at the screen) on Chrome, there's a tiny "keep" next to the file on a dropdown dialog that quickly disappears and it does generate a .zip file; Thanks.. So oddly enough when the array is spun up and idle all six lights are on but steady; I can live with this either way but just bring this up to the attention of the developers (if they monitor this forum) that this is not a controller issue as the same hardware does not exhibit this behavior when running TrueNas Scale. I was using ZFS now BTRFS, that may give a clue. Thanks

Well I re-ran the diagnostics two more times and after the animation stops, I select DONE and there's no zip file on my desktop, only the file that I uploaded. I'm using a Mac system, don't know if that might be the issue. I do see that in disk1 there's a docker folder that contains the docker.img. I assume this the file you are referring to, so I found a solution on the forum and moved the docker files to the cache, re-install the plex app and all seems to work fine except the 4 lights on the QNAP are still blinking away.... Attaching new diag report, no zip file generated. How do I open this file so I can see the text Unconfirmed 430608.crdownload

Here is the diag report Unconfirmed 514408.crdownload

Hello all, I'm moving from TrueNas to Unraid using my NAS enclosure and drives (QNAP TS-673A 6 drives). My hardware configuration is as follows: 6 drive array (1 parity drive) with BTRFS. 2 NVME 1Tb drives assigned to cache. 1 64Gb USB drive for boot. As for additional software I've installed the BinHex Plex server, placing the docker containers data in the cache pool, and assigning the plex media share to reside on disk1. The installation and management of Unraid was very easy and Im positive I'll purchase the license. However compared to TruNas there's a peculiar behavior when using Unraid; Four of my disk activity lights continuously blink as if the drives are being accessed. The web page shows all drives are on standby, and I verified this via smartctl on the terminal. Any idea as to what could be causing this ??
