Endy

I am not going to disable everything for a week or possibly even longer. Things like Emby server get used everyday. I've uninstalled all the plugins and dockers I can do without for awhile and that will have to do. This leaves Emby server and Delugevpn. Interesting thing to note. When uninstalling plugins, I noticed that my disks reappeared again, just like when I uninstalled system stats a few weeks back. I'm not sure which one did it because I had uninstalled a few before I noticed. Useful Link, Unassigned Devices, Speedtest, Preclear Disks, Powerdown Package.

This is what I am seeing.

I really have no idea what I am supposed to be doing now.

Dynamix Stats was ruled out the last time this happened because I had uninstalled it the time before. Do what command when what issue happens? It's in the middle of happening right now. I have not restarted the server. The only difference between this time and the other times is that my shares are still accessible at the moment despite my array saying offline. (Previously if they've been accessible, it's been for only a short time.)

I should note that I am still able to access my shares this time.

Ok, it just did it again. Looks like it happens about every 5-6 days. So what's the next step with that command still running?

It's running. If it follows the pattern, it should happen again within a week.

Well it happened again. For the following, when you say locally, do you mean I have to hook up a monitor and keyboard, or can this be done with SSH? Also, I am not sure if it's relevant, but when using powerdown -r in SSH there was this message.

Thanks Squid. I don't need to run that plugin so I'll just leave it uninstalled. In the meantime, I guess it's just a waiting game to see what happens.

I didn't know another way of getting the diagnostics file off of the flash drive at the moment so I had to shutdown the server so I could put the flash drive in another computer. So these are the results with everything back up and running normally.

Here's the syslog. syslog.zip

Ahh... thanks. Got it. Here it is. tower-diagnostics-20151225-0925.zip

post the full diagnostics I can't. It gives me a 404 error.

I uninstalled the system stats plugin and my drives showed back up again briefly. I still couldn't connect to my shares with the message "A device attached to the system is not functioning". All drives disappeared again and in the syslog and I am now seeing a slightly different message. Dec 25 09:02:01 Turtle crond[1427]: exit status 127 from user root /usr/local/emhttp/plugins/dynamix.system.stats/scripts/sa1 1 1 &> /dev/null

It happened again. I tried to get the diagnostics, but it gives a 404 error. I'm attaching the syslog entries from overnight. Looking in System Devices under SCSI devices, it does still show all drives. I also noticed that my share are still available. (I know they weren't the first time this happened. I don't think they were the second time, but my memory is not clear enough to be 100% sure.) Edit: I may have spoke too soon. I am now having problems accessing the shares. CPU Utilization is not showing a percentage. (The percent sign only, but no number, not even 0.) Memory usage looks normal. It's Christmas day so i realize I may not get a response for awhile, but I will try to leave it like it is in case I need to check anything else while it's in this state. Syslog.zip

New power supply is in. Because it's an intermittent problem and I can't purposefully recreate it, I'll only know if it's fixed after giving it some time. If there are no more problems, I'll report back in a month. (If there are, I guess it will be sooner.) That also hits the monthly parity check since that's what the server was doing the last time the problem happened.

Define "dangerous".. It's not like he was told to take apart an old tube Tv (which could very likely kill him if he didn't discharge it prior to). HV with minimal amperage, he may just get a prick or two. More serious, and still likely the PSU, but any possibility his flash drive is becoming corrupt? Since configuration is stored on the flash, unless this is only read at boot, and then store in RAM (uncertain). I only opened the power supply to blow it out. (It was very dusty even though I blow out my pc's every few months.) While I am not an expert with electronics, I am comfortable enough to do that. (I have fixed an LCD TV of mine by replacing popped caps... and without killing myself in the process! lol) What Squid told me to do I didn't even have to have the wires connected to the power supply to do. (Because it's modular.) As to the flash drive. I do not know if that could be the problem or not. I will say that it is a brand new flash drive that I bought specifically for Unraid. I have put it in a Windows pc and ran a quick check and it comes up as fine. What I am wondering about is with the popped caps, how that would affect the power supply. I am getting the proper volts and everything turns on. My guess is that maybe I am not getting the amps that I should be? If so, would this then cause the power supply to use more electricity? I've only recently added a UPS, but I notice that the load on the UPS is around 153w when the Unraid server is doing nothing. The only other 2 things hooked up are an 8 port gigabit switch and an HDHR4 tuner.

Well, I ordered this. http://www.amazon.com/gp/product/B00918MEZG I'm considering cancelling and ordering the 450w instead. I'm not sure I need more than 37a. In the near future I don't see myself having more than about 8 drives. I will be switching to a 6th gen i5 and a new motherboard probably within the next year and I will probably be using a few pcie cards.

Yeah, I found that too. I'm not using the GPU power, so it wouldn't be a problem to take from there, but I'm not sure I want to take from the CPU.

I'm still thinking about trying it, but I do have a question. You said the video card power is on a separate rail. So with 2 rails, what is rail 1 powering and what is rail 2 powering? With the modular power supply, it would be easy to take 1 of the 12v yellow wires from the a video card line and splice into the 12v of a molex/sata line. (That is, if I am understanding what you mean correctly.) However, I may just need to bite the bullet and get a new power supply. (Anyone want to buy a Ceton Infinitv4 and a Ceton Echo from me? lol) I took this one apart to blow the dust out and it looks like there's at least 3 popped caps and a couple of others that might be. I also still need to check the other power supply I was using because I don't think it was a double rail (but I don't know that for sure). So that wouldn't explain why it had a problem. At the moment it's powering my HTPC and running fine.

Soldering I can do. Identifying wires could be a problem, though. Once the parity check is done, I can take out the power supply and have a look.

It looks like my power supply is actually an earlier version of the one you linked to. The power distribution seems to be just a little different. 384W(32A) for the 12v rails instead of 456W(38A). I probably bought it before 2009. The 650 is a little newer, but you are right, it is probably the same way. I will look through the power supply thread later. (My morning has been eaten up by this problem.) But what I would like to know is why doesn't the problem show more often? Like right now while it's running a parity check which is what I am assuming triggered it during the night. Another question would be is if this is the problem, then what can I do about it for the time being since I can't get another power supply for awhile?

If it's this one, not single rail so it's really only giving half to the drives. That looks like the one. I do not understand single rail.

For the second time my array has gone offline and all disks were missing. (Including cache and the Unraid flash drive.) Also missing were the reboot and power down options. The first time this happened, I couldn't get it to boot backup at all. It would get about halfway through Post and then just sit there. I was actually getting ready to upgrade the hardware so I went ahead and did that assuming the the likely culprit was the motherboard. (It's an old old motherboard and the audio chipset was already fried.) The upgrade consisted of parts that had been in my main pc. An AMD Phenom II x4 925 processor, a Gigabyte GA-MA770T-UDP3, 16GB of ram (I forget brand, but decent), and I switched out the power supply with a 500w Enermax Liberty power supply that I had in another computer. (The old power supply was a basic Antec 500w power supply.) Basically all different parts except for the hard drives. The hard drives are 2 new HGST 6TB NAS, 2 WD 500GB greens, 1 WD 500GB black, and 1 Intel 180GB ssd for the cache. I should also mention that the WD drives are connected to the sata on the motherboard while the ssd and the 2 HGST drives are connected to an sata card in a pcie slot. It's been running for about a week with no issues. Woke up this morning to find the array offline and all drives missing. Had to do a hard reboot and it did boot up just fine. All drives are back and the array started. A parity check is in progress from an unclean shutdown. When it happened the first time I was in the middle of transferring a lot of files to the Unraid server. This time I think it happened during a scheduled parity check. This tends to make me think that the problem happens under load, but the problem with that is that it doesn't happen every time. I have done a lot of file transfers and also a parity check within the last week and there were no problems. I am new to Unraid and I haven't come across a similar problem in my searching. I really don't know what it could be. Is a 500w power supply not enough? The Enermax is modular, do I need to add more power supply cables to split up the drives more? I could also swap it out with a 650w Enermax Liberty that I have in my main pc if I had to. Any other ideas? I tried to get a diagnostics report before rebooting, but it came up as a 404 error. I'll attach the one after it came back up. turtle-diagnostics-20151215-1036.zip
