Hi,

Pretty new to this NAS thing, only set up my Unraid server October last year. Had things running pretty smoothly, only really wanted my own NAS for Bitcoin nodes and for media streaming.

Anyway, some time in December I think it was Jellyfin stopped working randomly, so just rebooted the NAS hoping this would fix the issue. It did not, went to start the array and noticed my 2tb cache drive was "missing". Which also meant I couldnt start the array as its "missing a pool disk". The only way for Unraid to recognise the disk again is by powering down the server, waiting a few minutes and then rebooting. This cycle repeats every couple of days. I havent had a chance to dig deeper due to some family issues, but yesterday I pulled it apart, reseated the NVME drive as well as adding a heat sink in case it was a heat issue. No change unfortunately, the dockers are missing again thanks to the cash drive "missing".

I have added a couple of pics to show what is happening after a reboot, which isnt enough to temporarily fix it. I was wondering if anyone had an idea what is going on with my server please? Could it be the drive is faulty? Appreciate your time to read and view. Thanks.

Attach Diagnostics ZIP to your NEXT post in this thread.

@trurl zip file attached. Thanks mate.

NVMe device is dropping offline:

Mar 15 00:41:33 TheFamily kernel: nvme nvme0: I/O tag 18 (d012) opcode 0x2 (Admin Cmd) QID 0 timeout, reset controller

Mar 15 00:42:54 TheFamily kernel: nvme nvme0: Device not ready; aborting reset, CSTS=0x1

Mar 15 00:42:54 TheFamily kernel: nvme nvme0: Abort status: 0x371

Mar 15 00:43:14 TheFamily kernel: nvme nvme0: Device not ready; aborting reset, CSTS=0x1

Mar 15 00:43:15 TheFamily kernel: nvme nvme0: Disabling device after reset failure: -19

Try this: on Main click on the flash drive, scroll down to "Syslinux Configuration", make sure it's set to "menu view" and add this to your default boot option, after "append initrd=/bzroot"

nvme_core.default_ps_max_latency_us=0 pcie_aspm=off pcie_port_pm=off

e.g.:

append initrd=/bzroot nvme_core.default_ps_max_latency_us=0 pcie_aspm=off pcie_port_pm=off

Reboot (or power cycle the server if just a reboot doesn't bring the device back) and then see if it makes a difference.

thank you for the reply. I am a little lost TBH, this is what I found. I think I am on the right track but quite find the specifics you mention? I have attached screenshots of what I did find for you to refer to. Thanks.

Your screenshot is showing where the information you need to edit is stored. But you can edit it in the webUI as explained.

In the webUI - MAIN - Boot Device - flash - Syslinux Configuration

Make sure the slider at the top is Menu View (instead of Raw View).

Several sections are shown, edit the append line in your currently selected section.

Awesome thank you. I have made the change and has been running for around 24 hours. If its going to fail, it should be within the next day or 2. Thanks again.

It seems the issue has been fixed! Thanks for your help, appreciate it!
