thats correct , syslinux after initrd=/bzroot should look like this : initrd=/bzroot nvme_core.default_ps_max_latency_us=0 , you can just add it to the end

Hi, i know this is late , a long time down the road. but in case anyone else hits this. the reason this is happening is because the ASM2824 controller sleeps the drives before the os has a chance to probe them (depends on nvme controller.) to fix this issue , you have to disable nvme sleep or change the time to wake, appending this to grub works : nvme_core.default_ps_max_latency_us=0 , you can try 500 to get a lower power state , but anything beyond that is likely to cause the disks to not show up at all. i have tested this on Z690 , Z790 and W680 chipsets , it solves the problem on both ASM2824 and PEX8729 , PEX88088 controllers.

i have always used this script : #!/bin/bash tmp=$(virsh list --all | grep " vmtest " | awk '{ print $3}') if ([ "x$tmp" == "x" ] || [ "x$tmp" != "xrunning" ]) then echo "VM does not exist or is shut down!" nvidia-smi -pm 1 else echo "VM is running!" fi worked for years for me , i trigger it every 5 seconds.

literally just fought this battle , a firmware update did the trick for me. also forcing write cache on using : smartctl -s wcache-sct,on,p /dev/sdX

Hi, Tom i have been using unRAID for 13 years now. I love it. however this issue did come up for me when using 6.** specifically. Opened a ticket with support and it was closed as a hardware issue which i accepted. So in getting that news i installed truenas ( some years ago). it still runs today with the same hardware without issue. Money not being much of an issue for me as i use unRAID for my photography business. I invested another 5k in 2 systems. All brand new hardware , including SAS/SATA controllers / Cables. This error hit me after about 3 months of using it disabling 2 of my disks overnight. The second system lasted for about 5 months hitting 1 failed disk overnight. Replacing the disks on both systems , This time failures on month 4 and 6 with different disks plugged into different cables. Then i proceeded to installed truenas on both systems , they have been running for a year and a bit. I built a new unraid system at this time with new hardware. The problem cropped up around month 8 this time , using NAS rated WD RED's. Im at a loss at this point , very torn. i love unRAID. but i cannot trust either hardware in general or unRAID.....im just not sure which one it is right now.

I used this with success on my P4's https://www.lxg2016.com/55875.html

you can use vGPU , its a complicated process and very hacky. i have 2 p4's split up myself.

I think i found a possibly major defect. my diagnostics are running the beta , however this happens also in 6.8.3. Lets start off with the issue. after 7-8 days roughly. the disks will fall out of the array. ( i know you will say its the cables , the cards ,hdd ect. however its not). this usually can be fixed by removing and readding the disk to the array(letting it rebuid). however when i do that. it shows the disk as empty now....all data is gone. i have tried this on several different combinations of motherboard/cpu , controllers...all amd systems. pulling out the motherboard and cpu and swapping with a 7th gen intel cpu works fine, i left it running for a few weeks with no issues. i have made another unraid flash drive , started from scratch. issue still shows up. tried this hardware in many combinations : B450F motherboard A320I-K motherboard AM4 3400G AM4 3600 Hitatchi 3tb disks brand new 8tb wd disks brand new 8th seagate compute disks timetec memory , gskill memory in varios sizes and even new packages LSI 2008 based controller PERC H310 flashed to IT mode H200 HP flashed to IT mode motherboard sata connectors Brand new 800w corsair power supply. the logs show like the disk is failing , however if i swap the disk out. with a brand new one....another will show failed until this happens to all the disks. then the brand new ones will start doing the same. im completely lost at this point....i have had to revert to my intel machine running my backup array. all the parts listed above except the 3tb and controllers are brand new. those parts when swapped into the intel system have no issues. all of the HBA's are cooled , nothing in the system builds have anything running hot. all within a 40-50c max operating temp. hdd's are running at a 35C average. i have tried different pcie slots, controller combinations , reflashing controllers. they work in the intel system. i have been running unraid for 10+ years , this is the first time i have had an issue. fileserver-diagnostics-20200623-1206.zip

yes , you will need VT-D to do passthrough (pass hardware through to VM's) the only other way is make a data store on the drives and use them inside the VM (not recommended) you should be able to find an 1155 socket cpu to support VT-D for 200-300$ depending on that motherboards configuration you will need a PCIE sata controller , i recommend a M1015 / i9220 based card, with 2 SAS forward breakout cables.
