Should be add each disk in individual RAID, not 100% confirm because never attach disk under Magaraid. Use HBA could solve this problem.

17:00.0 RAID bus controller [0104]: Broadcom / LSI MegaRAID SAS 2208 [Thunderbolt] [1000:005b] (rev 03) Subsystem: Broadcom / LSI MegaRAID SAS 9286CV-8e [1000:9291] Kernel driver in use: megaraid_sas Kernel modules: megaraid_sas /sys/kernel/iommu_groups/42/devices/0000:17:00.0 Or passthrough the SAS controller ( group 42 ) to Windows VM then config it.

Best and simple.

Then it should because you need in BIOS / Windows environment to add SATA disk be RAID members, so that it can recognize. BTW, you won't see RAW disk SMART under RAID controller.

For my understanding, this not a true SAS enclosure, it just a cable extension to external box, so that's why connect 8 disks then need 2 SAS cables. All just use SAS socket / cable but nothing relate SAS. ( I may be wrong ) The RAID function just provide by the RAID controller, nothing relate to enclosure. BTW, you should see the disks, what disk type in enclosure SATA / SAS ?

Pls provide the SAS enclosure detail / model.

Still same as 1st one.

Try <Ctrl><R>

This one. Depends on mobo, even Asus X299 AII, the extra lane was support for extra M2 not for PCIe slot.

Your SAS controller was RAID type, there are no any SAS device have detect in Unraid. Pls confirm any SAS device found in MegaRAID BIOS first.

Docker utiliize not means memory usage, it ref. to docker image file usage for my understanding.

Won't be cache / RAM.

This indicate something relate router with Unraid, as you have switch, pls make a test to verify, try disconnect the router during large file transfer ( set DHCP lease time longer enough, so no renew during test)

Pls note B is Byte and b is bit.

Plugin just call bunker to perform different task, pls check does file permission issue, try use tools - NEW PERMISSIONS to fix that and re-run bunker. Daily add & verify file ( bunker CLI ) without issue. This normal.

I miss that your last Ookla speed test got abnormal resut, so it shouldn't storage related.

Would it be storage slow issue for writing ?

So, it likely not docker / docker network issue. You said other device no problem, speed test over 100Mbps ? Does router have QoS apply ?

Never got docker network low performance, could you try docker openspeedtest for local test, easy reach 8G actual network traffic. openspeedtest/latest

It likely Router / ISP issue, check router WAN linkspeed too. Speedtest by Ookla Server: XXXXXX ISP: XXXXXX Idle Latency: 2.30 ms (jitter: 0.20ms, low: 1.98ms, high: 2.56ms) Download: 395.71 Mbps (data used: 178.6 MB) 9.17 ms (jitter: 1.07ms, low: 2.90ms, high: 12.81ms) Upload: 782.11 Mbps (data used: 372.9 MB) 8.27 ms (jitter: 0.84ms, low: 2.74ms, high: 11.07ms) Packet Loss: Not available.

No, I don't need high performance in vitual to vitual, no application need that. I only need real media transfer 1GB/s would be fine, actual media just around this level.

This is direct IP accessing. Pls check does any abnormal found on supervisor log and general log after fail access from LAN PC.

No. Try different browser. Do you access at LAN PC ? http://homeassistant.local:8123 or http://192.168.0.125:8123 Post Unraid network setting page screen capture and diagnostic.

Log full with "nchan" error. Due to those error / crash, disk error may not relate to disk controller problem. Any VM / Docker running in system ? Pls try memory test to ensure system in health first and post full diagnostic, also try stop all unnecessary docker / VM / applications to rule-out the problem.

Set it by command line or use "Tips And Tweaks" plugin setting those two parameter, of course, you must have enough memory to cache whole file.
