Good to know, I'm also running dual parity.

Thanks, that's great to know that things should work. As an aside question, I've been wondering why my parity checks run at about 110MB/second, but my drives are capable of above 200MB/s. Am I missing something in the calculation or is it a case of slowest drive, or something else?

I wondered about this also, as a valid and healthy parity seems to be a key requirement. I've had a good parity history, and run at the beginning of every month: So I had a good parity check about 10 days ago. As far as I can tell, none of my drives have any SMART errors and are recent drives purchased within the past year.

Hi All, I've just received 2 new drives for my Unraid setup, to replace 2 older drives in the array. I'm currently using 6x 8TB drives (double parity and 6 data) and 2x 6TB drives (2 data). The 2x 6TB drives are the candidates for replacement/upgrade with 2x 8TB disks. I've been searching around and googling and haven't been able to find any info apart from a thread using unraid 5.0.3, which was also using single parity, and he didn't seem to follow the correct process that I'm familiar with. Anyhow... So my question is, does the current stable 6.8.3 (When using double parity) support replacing 2 disks at once? Has anyone attempted this, or is it a no-go idea?

@Juxsta can you post your full XML in a code block? I think your USB is not being passed through. Edit: Nevermind, saw that you did already.

You checked both the videos, followed all the instructions and made sure to pass through the sound devices exactly as advised also?

@Juxsta You might benefit from the HOWTO I wrote over here: I spent a lot of time putting this HOWTO together, and I usually refer to it when I see others struggling with the same. Let me know if you found it useful. 👍

So I rebooted and checked the BIOS time, which I apparently cannot edit. The BIOS System Time is already set exactly 1 hour back, so I assume it is UTC set. After startup, still see the error: ntpd[2369]: kernel reports TIME_ERROR: 0x41: Clock Unsynchronized Checking Unraids NTP server shows: Linux 4.19.107-Unraid. root@blaster:~# ntpq -p remote refid st t when poll reach delay offset jitter ============================================================================== LOCAL(0) .LOCL. 10 l 549 64 0 0.000 0.000 0.000 +time1.google.co .GOOG. 1 u 10 64 377 16.366 -0.627 4.196 *time2.google.co .GOOG. 1 u 9 64 377 15.926 0.635 2.820 +time3.google.co .GOOG. 1 u 2 64 377 15.671 -0.948 3.517 +time4.google.co .GOOG. 1 u 5 64 377 14.791 -0.992 1.455

Hi all, I'm having a strange issue with one of my Linux VMs. Its a QCOW2 install of Home Assistant, which has been working without issues for a long time. My other VMs seem to work fine, mostly Windows 7/10 VMs. Yesterday, I upgraded my Ryzen CPU to a R9-5950x, and required stable BIOS version, and the issue began after this. As part of the process the BIOS was reset, and I set everything back to correct before booting Unraid. Upon starting up, this VM does not start but seems to crash with this error on the screen: I've checked my unraid logs and can see that this error repeated 3 times: ntpd[2358]: kernel reports TIME_ERROR: 0x41: Clock Unsynchronized I've also seen this, which seems to indicate the wrong time zone (I'm in +0100) kernel: xt_time: kernel timezone is -0000 I checked and my Unraid Timezone is already set correctly: I've tried testing with a fresh latest version of the QCOW2 file, located on this page. Direct link to the file is here, via the same page. Is the Real Time Clock possibly causing the issue? Any ideas how I can resolve the RTC issue?

Update: New Zen 3 CPU installed, seems to be working well. BIOS 2802 works well, but most importantly, temp monitors seem to be working without changing anything.

Update: upgraded to BIOS 2802 in prep for the new Zen 3 CPU. Temp monitors seem to be working as before, and I haven't changed anything otherwise.

Read and you'll find it on this thread.

I'm currently on 2407, but my Ryzen 9 5950x just arrived, so I need to upgrade. I've downloaded the 2802 non-beta and the 2816 beta BIOS, but I'll be using the non-beta for now as it has AGESA 1.1.0.0 needed for Zen 3. For the record, I think Zen 3 requires at least AGESA 1.0.8.0, in BIOS version 2607+. Gonna do that first and see if temp monitors are still working, before swapping in the new chip. @Kash76 this might be useful for you.

It does seem cheaper and more straightforward to use DAC where possible, and that's been my own experience in server rooms also. But at home I'm looking at getting a Mikrotik CRS305 4/5 port 10Gb for the DAC cables to terminate to, which would make the whole thing easier. It also has a 1GGbe uplink port which is handy, so no transceivers needed, with the potential complications that they bring. Both my current servers are in the same room also. Would be a good start, I guess.

Yeah I get that, its a 3.0 NIC which isn't magically going to become 4.0. Just saying in an ideal world. ¯\_(ツ)_/¯ Any advice from your experience on if going all-ethernet or mixing in SFP+ DAC?

My main use is to extend my basic VLAN usage, but I'd like to get more into L3 packet and protocol filtering, but I don't do much of that at home right now. Tbh, I'm not really sure on where I want to go with it, but I'd at least like to have a better VLAN implementation.

From the Wikipedia Page: In an ideal world, I'd be able to get 1.969 GB/s or 15.752 Gb/s. But I think I'd be happy with 0.985 GB/s or 7.88 Gb/s. Still trying to figure out if I should invest in fiber on the Mellanox Connectix-3 like this or just stick with all-through ethernet and get an intel card like this. The Connectix-3 is clearly cheaper, but the cost of fiber cables and transceivers doubles the price of the card. I could of course go with direct attached copper cables, but I'm unsure. I'm starting fresh here, so I'm hoping from some advice on where to start? Edit: There is of course Intel SFP+ cards like this also.

Thanks @JorgeB I've been trying to read through various manuals and such to see if the Mellanox ConnectX-3 will work in a x1 slot, but I can't find any info anywhere. I figure I'll probably just hack one of my x1 slots open and see how it goes, I've seen a lot of guides online on how others have managed it. @Ford Prefect I think I could be happy with 8Gbps from a 10Gbps card. I'm currently teaming to achieve 3GBs so that would be a huge improvement. Still wondering if it will work, but from what I've seen in other places, it should.

Yes, I've read that using the Mikrotik controllers for L3 stuff is a bad idea. I'm considering getting the CRS305 4/5 port and maybe getting a more substantial main 1Gbe L3 switch for VLAN work. Would that be a better idea?

Will that CSS610 do VLANs and such? Looking to upgrade my main 1Gbe switch and add 10Gbe in the near future. I'm also using Pfsense for my router, but dumb switches elsewhere.

Hey thanks for responding, but I think maybe there is a misunderstanding. I'm talking about PCIe x4/x8 cards (As in PCIe 1.0/2.0/3.0 card in an x4/x8 physical form-factor), not PCIe 4.0/4.x card (As in the PCIe 4.0 standard). I'm definitely not hoping/looking/dreaming to find a PCIe 4.0 card anytime soon. I've been looking at a card like the Mellanox ConnectX-3 like in this ebay listing. Its a PCIe x4 card and I figure someone on this forum has to have one, and maybe someone in an x1 slot. ¯\_(ツ)_/¯ Really just trying to know if it will work and if so, at what speed? Any ideas?

Hi all, I'm still looking into this and hoping that someone may be able to share their experience with using 10Gb cards? Has anyone had experience with using a 10Gb card in any 1x slot? Thanks for any advice.

Just browsing this sub and noticed this thread.I run ECC in my Ryzen Build. Maybe I can help? My setup, all details in my signature. I did a lot of web-searches and reading to pick this motherboard, and it seems to work very well. The RAM I use is MTA18ASF4G72AZ-3G2B1. Just google that product ID for more info. 👍 Everything is running in Multi-bit ECC and works great. I run my virtualised daily desktop and VR gaming PC from this. If you have any questions, I can try to answer.

@Maddeen This seemed to be something with the earlier BIOS version I was on. I'm planning to get a Ryzen 5000 chip in the future when they become generally available, so I've been wondering if anything will change again with that upgrade. The newer Ryzen 5000 chips require a BIOS with AGESA 1.0.8.0, but I think they recommend AGESA 1.1.0.0 for full support.
