Thank you!!

Is this a symptom of the issue? All of a sudden none of my SMB shares (guest only) are no longer able to mount.... Unraid Server (Odin) is trying to Mount an SMB share from my OpenMediaVault (OMV.LOCAL or 192.168.X.XXX either way it fails to mount).

I have serveral Pools: 1 - 6 x 8TB spinning Seagates 2 - 2 x 1.92TB NVME Samssungs 3 - 3 x 3.84TB NVME Samsungs 4 - 5 x 2TB NVME (mixed) All of them are in RAID 0 and I can't do better than about 600 MB/s when transferring from my Windows 10 Machine to my Unraid server on a 10gbps network. I've installed iperf between my Unraid Server and my desktop and iperf3 tells me I am consistently getting 1 GB/s (roughly 9gbps). I have a single SSD in my unraid server for my VM's. If I just transfer files to that, I get 1 GB/s with Samba from the Windows 10 machine. Why would my pools consistently only get 600 MB/s. I get the spinners might make sense, but the NVME's? Yes they aren't the best NVME, but when tested singularly before deploying to the server, they all pulled over 700+ MB/s and most pulled well over 1GB/s. Is there some limitation to btrfs? I've tried RAID 0 and "Single Mode" and nothing does better than 600 MB/s.

Please see your last question. I explained the basics to unraid. Unraid does NOT treat an array like a traditional file server where all drives are used when reading and writing. Unlike a traditional RAID 5 where blocks are written to all disks, unraid only writes a file to a single drive (and the parity drive if using a parity drive). You will see no additional read performance or write performance (unless using a cache for writes) faster than a single drive. Files are written to a single drive.

I guess I don't understand your question.... Are you getting 200-400MB read or writes? Hard drives? SSD's? whats your array look like? At a basic level, unraid treats each drive as it's own read and write. It presents itself as one large drive as a share, but when it comes to reading and writing, it doesn't span across multiple drives like traditional RAID 5. So a 200MB/s read would be about right because that's all a single drive would be capable of. The Cache drives are simply used for writes and then moved to the spinning array once a day (usually, unless doing something different than standard). Now how you are getting to 400MBps? I am assuming that's reading from the cache drive? Is it a file you just copied over and then tried to read right back? In that case it's because it is on the cache drive and hasn't done the nightly move. How fast is your cache drive? 400MB/s could be about right with an SSD that small.....

I've run two Unraid servers for several years now. They've had plenty of upgrades over time. I've also been running a 10gbps network between my servers and office desktops for years. My main Unraid server has an array of 6 - 8TB drivers in Single Parity Mode (40GB usable). My other Unraid server just has 5 - 8TB drives with no Parity. I just use it as a backup to my main server using rsync. Each night around 4AM, I have an rsync script to copy changes from one to the other. I use dual 500GB SSD's in Raid 0 in my main server to give me awesome write speed to my main server from any of my desktops. That works great for writes since I never write more than 1TB of data in a given day. But the read speeds..... oh the read speeds. I understand the unraid thought process of spinning down drives and if you are running just 1gb ethernet, even a single hard drive can max that out. But 10gbps networking means I'm leaving a lot of read capacity behind. So my thoughts.... I am thinking about taking 5 - 8TB drives and putting them into RAID 0 as a Pool. In my array I would load up with how many drives I need to have storage to cover the data in the Pool (right now I only have about 20TBs worth of actual data, so 4 - 8TB drives in Single Parity should work). I would then run rsync every 6hrs to copy from the Pool to the Array in case the pool becomes corrupt. This should give me roughly 700-1000 MBps read and writes from the pool. While still not saturating the 10gbps network, it's more than enough for what I do. Thoughts? Is there a better way to do this?

Just wanted to say this plugin is great! Although makes me realize how I need to use a better GPU than a P400 (just transcoding 1 4K to 720P is taking 70% of my GPU Memory). The update to do multiple GPU's is awesome. When I first installed it picked up my currently un-used GPU (just an extra I have in the box for testing VM's), but being able to switch to the one I use for Plex is great! Thank you!!
