  1. I’ve posted on this topic before, but the topic got a bit sidetracked (by me). Are there any known issues in using NvME’s in a RAID5 Cache Pool? In one of my UnRAID servers, right now, there are 6 2tb NvME’s, RAID5. Writing to Cache Pool, very slow at 350MB/s, read at 750MB/S. As an unassigned Drive, a single NvME r/w at 900 MB/s+. I then tried 6 2.5” 1tb SSD’s in RAID 5, 1.4GB/s read and write. Same server, same settings. There must be some sort of bug or incompatibility, to be getting only 350MB/s on the array, when disk speed test shows each drive capable of 2000+ MB/s, and an array of the same number of 2.5” Drives fully saturates the line. I had a similar issue before, when testing 40GbE, but the r/w speed was capable of 10GbE saturation, just not 40GbE. I rebalanced the array too. No difference Any ideas here?
  2. I was going through the chelsio manual to tune a T-580. Next step was to unload the drivers. I did. The step after was to reload, but that is not working for me. The NIC now doesn't show up. Did everything I can think of. Can someone tell me how to get it back?
  3. Send me a PM, I can help you out? Has anyone had luck getting 10GbE to work in High Sierra? I spun up a few MacOS VM's and can't get networking active. I only tried in HS, trying in mojave next. I may have to plug in gigabitE to get it to work in HS. Curious if anyone else has the same issue?
  4. you can plug the card into a windows machine and adjust config there, if it isn't persistent. That's how I handles mine.
  5. This has been something on my to-do list for a while, and feeling like knocking it out now. I want to be able to send clients files from cloud storage. Instead of utilizing gDrive or Dropbox, I want to use OwnCloud or NextCloud, or alternative to create shareable links with a custom domain. So let's say either a domain I own or ddns domain. I want to send a client files to download with: Dr. Ooh has sent you a file to download: www.nARctic.cloud/xxxxxx.rar for example. That's the bare minimum. Ideally, the landing page the client reaches is custom as well. I'm thinking that's something I could set up in a web server on one of my servers. Yeah? How do I go about it?
  6. Oh, and also, along the same lines, I jumped down a rabbit hole searching for VNC or Virtual Desktop Software that can display multiple monitors from one VM; couldn't find much yet. Anyone know of software to accoomplish this? (It looks like another feature of Grid/MxGPU.
  7. GPU pass-through is no doubt a great tool for unraid, but I am very curious about virtualized GPU's. I am just starting to research it right now. But it seems NVIDIA Grid and AMD MxGPU are the available options. I could have sworn I heard of other, open source, ways to do it. The use-case would be for remote VM's. Is it possible to use my installed GPU's to provide graphics acceleration for virtual machines? In my layman mind, it seems to me, it should be possible to do with one VM, without advanced software. Or, by rerouting the output of the GPU somehow. MxGPU and GRID do this, but are geared toward multi-users, running lots of VM's. For me, it would be an option to purchase the Tesla or Quadro GPU's and software to do this, if unraid supports such. But, even better if I can use my current GPU's to accelerate VM Graphics. In my various unraid servers, I have RX580's, 1080TI's, 1060's, and an RTX2080. Wondering if I can utilize any of those for this purpose.
  8. Cool. Thank you. That’s definitely why I couldn’t get it to work. I’ll give that a go.
  9. thanks. I identified the enclosure, pulled it, all clear since then.
  10. I couldn’t find anywhere in documentation if unraid will support direct connection and connection through switch either. I’ve not been able to get that setup either. for instance, dual port NIc connecting to two separate subnets. Port 1 -> 10GbE Switch On Subnet 1 Port 2 -> Direct attach to client or server on Subnet 2. I’ve tried with no success. Is that possible too?
  11. Now that you mention it, a single unified view of all data is a desired goal, I didn’t know this was possible, but the general idea is upcoming on my list. I’d like to learn more. The reason behind the initial post is two-fold. I’m out of ports on both 40 and 10GbE Switches, and I need to add a few more servers to my network. Chelsio NiC provides for spider mode, allowing for 4 10GbE connections to a single server. Secondly, I’ve found that I am able to achieve faster transfer speed when initiated from VM’s. For instance I am able to achieve a 2.5 gigabyte per second transfer from a VM on Server 1 to any of my clients. Whereas initiating a transfer to the same client, from the same Share, from outside of the VM results in less than 5oo megabytes per second. No idea why. But a connection like that for select servers would allow me to create a separate network for machines that require that throughout but not that level of bandwidth.
  12. Is it possible to create a bridge between multiple physical servers? If so, how do I achieve? This is what I am looking to do with a couple of servers, either A or B. I want all clients to connect to a switch, then bonded NIC on the first server. All clients connect to Server 1 through the switch. All clients connect to server 2 and 3 through server 1. Server 2 and 3 ideally would share internet connection with Server 1. Only difference between option A and B is in A, servers 2 and 3 connect directly to 1. Server 3 connects to 2, 2 connects to 1. I assume there is no benefit there, and probably more complexity. Alternatively, It would actually be better for me to remove the switch from the equation. Could I connect a single client to Server 1, instead of the Switch, and then have either Option A or Option B? I tried setting this up with not much luck. But I likely wasn't approaching it in the right way.
  13. I did figure out the only as media device I have is a starch dual 2.5" to 3.5" raid box. I believe two of my cache drives are in it. Is there a way to ping the hdd light on the server that will show me which bay the device is in?
  14. Got it. Yeah, I thought it was an asmedia device. It's very peculiar. I don't have any asmedia devices on this particular server. The internal controller doesn't have an asmedia controller, neither does the LSI, the only other devices in the server are Mellanox NIC and 5 NvME to PCIe cards; none of which have asmedia chips, as far as i know. I will double check that. I updated LSI firmware and I am still having the same problem. I am thinking I may need to scrap this UnRAID install and start again. My bootloader backs-up 3 times per week, so I should be able to recover the entire config. Worst case, I lose the customizations for the server. All of the data on the array is replicated on two other UnRAID servers, so even if I lose the data, i'm covered. Although, I;d rather not have to re-load tera's of data if not necessary. Hopefully, I can launch a completely new config, reassign the drives, and turn out ok. What's the recommedation for next step? Anything else i can try before scrapping the array?
  15. thank you. I was wondering what that ASMT109x was. How do you know it is from the LSI HBA? I could have sworn tha popped up here and there before putting in the new controller, but I could be wrong. I'm working on updating the firmware. Is it possible to use sas2flash within unraid? If not, could you link me to instructions on how to upgrade the firmware? For LSI RAID controllers, I would boot into the management utility or use pre-boot CLI. WIth the HBA that isn't possible. I've been reading all morning, and I still don't have a clue as to the best method, other than creating a dos bootloader, which isn't quite going smoothly.
