Hi there, I'm running unraid version 6.10.0-rc2 with the latest version of linuxserver's Plex container. I'm using an i9-10850K and have installed the Intel GPU TOP plugin and checked that "card0" and "renderD128" show up when I run "ls /dev/dri" in terminal. I have the path for "/dev/dri" mapped in the plex container settings, and have enabled "HDR tone mapping", "Use hardware acceleration when available" and "Use hardware-accelerated video encoding" in the Transcoder settings in Plex. Previously, hardware transcoding was working flawlessly without issues, but recently I noticed that at the same time, some files are able to use hw transcoding, whilst others don't appear to be. This can be seen in the screenshot below: 1080p files using software transcoding is fine but when some 4K files also end up using software transcoding, my CPU usage spikes. I'd like to avoid software transcoding entirely if possible. Does anyone know what is causing this issue and why some files are able to use hw transcoding, while others are not? I've tried searching the forums and googling this issue, but can't seem to find any relevant answers. Thank you, I appreciate the help.

I understand, thank you again for your help anyway in trying to rectify this issue.

Hi JorgeB, sorry for the late reply. I was doing some testing in Windows instead. Right now I have a Samsung 970 Evo Plus Gen 3 drive installed in the M2_1 slot and a Sabrent Rocket Gen 3 drive installed in the M2_2 slot. The M2_2 slot is the one that keeps dropping offline in unraid. Even when I had the Samsung drive installed in that slot, it would drop offline and now the Sabrent drive does the same thing. I loaded Windows on the Samsung drive in the M2_1 slot and added the sabrent drive in the M2_2 slot as a secondary (D:) drive. I ran the pc with windows running for about an hour and every so often I would try to access the Sabrent "D:" drive and copy files onto and off of it from/to the Samsung "C:" drive. In the scenario above, the drive never dropped offline and always remained online and accessible throughout. The issue where the drive is first detected and then suddenly drops offline within 5 mins of booting only occurs in UNRAID. Could this then be an issue unique to UNRAID? Thank You for your help.

Hi JorgeB, I bought a Sabrent Rocket NVMe drive instead, and am facing the same issue as before where the drive appears online for a while then drops offline. I still have the code you provided in syslinux: append initrd=/bzroot nvme_core.default_ps_max_latency_us=0 Any idea what could be causing this issue? Is it really an issue with the motherboard? The drive appears fine in the BIOS. Thank you for your help. diagnostics-20220218-1330.zip

Thank You for your help and advice all this while! I've turned off the bt and wifi from the bios itself. And as for the nvme troubles, I actually managed to "fix" it in the dumbest way possible I think? Since my motherboard has 2 slots, I simply put it in the other slot and somehow it seems to be detected and works fine for now. I'll just have to keep in mind that if I get a second nvme drive for the original slot, it probably should not be a 970 Evo Plus so as to avoid this issue again. As to the potential explanation why it works in one slot and not the other, according to my motherboard specs, the slot I had it in initially was controlled by the mobo chipset whereas the slot I have it in now is controlled by the CPU, so perhaps there's some shenanigans going on there that I'm not familiar with. I hope this may help anyone else stumbles across a similar issue.

Okay, the new diagnostics are attached in this reply. Sure I will check the BIOS to try and disable the Bluetooth. diagnostics-20220216-1010.zip

Hi JorgeB, thank you for your reply! I have already updated the BIOS to its latest version prior to booting into UNRAID. Not sure what the Bluetooth errors are but could they be related to the wireless keyboard and mouse USB dongles I have attached? I tried the fix that you suggested, but I can't seem to even "see" the NVMe device in UNRAID although it appears in the BIOS. Also, under my "Syslinux Configuration", there is additional content after "append initrd=/bzroot", please see below: append initrd=/bzroot,/bzroot-gui unraidsafemode UNRAID is started in normal mode, not safe mode, so I'm not sure why that suffix is shown. I have appended the "nvme_core.default_ps_max_latency_us=0" after that as in: append initrd=/bzroot,/bzroot-gui unraidsafemode nvme_core.default_ps_max_latency_us=0 This does not seem to fix the issue. The NVMe drive does not appear under unassigned devices even after full shutdown and startup. I also tried removing the ",/bzroot-gui unraidsafemode" to make it as you suggested: append initrd=/bzroot nvme_core.default_ps_max_latency_us=0 However, the NVMe drive still does not appear under unassigned devices. What should I do in this case? Attached are the new diagnostic files. Thank you for your help!

Hi, I am an absolute newbie to UNRAID, and I am just trying to set up my server. I've only just got the system booted into the UNRAID OS, but I am facing this issue where my Samsung 970 Evo Plus 1TB NVMe SSD randomly disappears and only reappears when I shut down and turn on the server again. My Samsung 850 Evo 1TB SATA SSD and WD 2TB HDD (old reused devices) appear under unassigned devices just fine, but for some reason, after starting the server, the Samsung 970 Evo Plus NVMe SSD appears for a short while then disappears. It is a brand new drive so I'm not sure what the issue is. The 970 Evo is in an MSI Z590i UNIFY motherboard which supports 2 NVMe drives, though I am only using one. I have attached my Diagnostics ZIP here. I appreciate any help and thank you in advance! diagnostics-20220215-2353.zip
