I'm on my Mac, just started transferring some files to my NAS's SMB shares using Finder. I switch back to the other workspace that has my browser (Chrome), and it happens to be on the tab that is the Unraid WebUI. I never even did anything in the WebUI, but it just auto reloaded on it's own, and I haven't been able to access the webui since. My file transfers continued just fine, and I was still able to access all my shares, and plex still worked, just couldn't get to Unraid's own webui. Restarted my Mac, and now I can't access me shares, still can't get to the Unraid webui, but plex is still running just fine. I never setup ssh, didn't' know I needed to, and pressing the power button doesn't shutdown. I'm trying to avoid a hard shutdown with a long press of the power button, as I do know that works.

I made no changes to anything, not my mac, not my network, not my router settings, nothing on unraid. Nothing. I had literally just got up, did some organizing of my recent downloads and just started dumping them to the NAS. I do use a commercial VPN, Proton in this case, but it's caused no issues in the past, but even so, I still turned it off, but still can't access the Unraid webui.

edit: ended up doing a hard shutdown, and it's back up and runningnow. Trying to understand what happened and why though.

Do you have an attached monitor and keyboard?

Way ahead of you on that.

Here's (001) what I had when I first plugged in the kb and monitor, last line is just me hitting escape to see if kb is working.

I had to rearrange a couple of things, and when I turned back to my screen, it looked like it finished starting up. A little surprised, I checked Chrome, and still not webui. I login as root on the CLI, check chrome again, still not webui.

Still confused, but I manually initial a reboot using the cli, but it hangs on this (003)

and even I knew I was just going to have to do a hard power down at this point.

It's back up and running now, webui is working, shares are all accessible over the network, and parity check is running. I did record the boot up as best I could with my phone, and I can post it to YT and share if you really want, though I suspect some log snooping might be more useful, if you're willing to help me. I'm assuming I should get ssh running too, if you could point me to the proper guide, I'll get that done asap. Something similar has happened once before, but it was not too long after I built it, so I just chalked it up to being an Unraid noob.

Here is the diagnostic file.davids-server-diagnostics-20260428-1503.zip

Checked my docker containers as I know had a few set to autostart, but only one, binhex-jackett, is running. None of them have autostart turned on anymore, even binhex-jackett that did start.

What happens when you try to access the Web GUI?

It's working. Trying to figure out what happened though.

Setup Syslog Server

So, don't write to the boot drive if it's a flash drive, which mine is. I don't have a reliable enough remote location, or even a reliable enough network, to go remote. I'm left with local, and since the whole reason I'm at this point, is because I lost access to any shares, using cache/share isn't a good idea. Now I'm just back to USB, only external this time, and since a flash drive isn't recommended, I have to use an external SSD, which just sound like overkill. Maybe I'm missing something here, but is writing the logs to the drive really that bad that i'll kill a flash drive that fast, because otherwise, I don't see a good option for those of us on a shoestring budget.

Writing to a flash drive will normally be OK as long as you only do it for a limited amount of time. It is only not recommended as it puts load onto the flash drive that can increase the likelihood of it failing. I have done it myself a number of times but then I am using an oldish USB2 flash drive that is less prone to failures of this sort than modern USB3 ones seem to be. If it is not the Unraid boot flash drive then the worst that can happen is the flash drive fails.

Another possible option that you have not mentioned is a HDD or SSD/NVME connected via a USB adapter or dock.

I guess I don't get why they aren't always on and running continuously by default. You never know when or what is going to happen, and if you only run logs after something happened, how is that going to help you?

Like the rest of the OS files, logs are kept in RAM unless you setup a place for them to be stored. They can be accessed from the webUI but are lost on reboot since they are in RAM. Since there is no "default" storage for all configurations, the user has to specify where they should go.

Any idea of the quality of the nand used on the 64Gb emmc in Steam Decks? Is it the same lower quality nand used in most flash drives, or does it have similar wear tolerance to regular ssd's? I've been trying to find a good use for it since I replaced it with a 256Gb ssd.

The 64GB eMMC in the Steam Deck uses 3D TLC NAND with a proper wear-leveling controller, so it's significantly more durable than a typical flash drive for continuous writes -- definitely a reasonable repurpose for syslog or similar.

If you want even better NAND quality on the cheap though, there are Innodisk 3ME industrial USB drives on eBay right now for around $4 -- these use MLC NAND which is substantially more wear-tolerant than consumer grade TLC flash.

This specific ebay listing is worth a look: 326046070546.

Could be worth migrating your boot drive to one of those depending on what you're currently using.

If you want to learn more about the subject, check the Boot Device Guide in the Boot Devices section of this forum.

Awesome. That is most useful. I'll look into the Innodisk for sure.
