Umbrel is unavailable after few hours

Support and Troubleshooting
1

Hi,
my Umbrel is working only few hours. Then it is unavailable. I tried all possible solutions from the discussions but without result:

  • setted static IP on router
  • setted static IP on Umbrel in dhcpcd.conf
  • re-flashed Umbrel on microSD card

All this steps I tried but it didn’t work. After few hours I lose connection to my Umbrel. Ping using umbrel.local works but SSH connection is refused and access using web browser to umbrel.local also doesn’t work. When I look at the router for data traffic, the Umbrel is connected but the traffic is 0 KB/s. Umbrel stops communicating and I don’t know why.
The only option is to unplug the cable. After the reboot, my Umbrel is fine again for a while.
Can you please advise me somewhere where the problem might be?

Please follow the instruction to generate the debug log from the troubleshooting guide and then read the 2nd tab DMESG about your hardware. See if there is some hardware failure there.
Seems to be a problem of not enough power. Maybe your power adapter is failing.

How long does it usually take to run a debug log? Mine has been running for over 12 hours and still not complete? Thank you

I have some errors about USB:

[   14.101367] usb 1-1: new high-speed USB device number 2 using xhci_hcd

next errors is

I have 5V cooling fan. I tried switch it to 3V for power saving. Can it help?

5

Could help yes, but that means your power adapter sucks. Remove anything that is nor necessary and is connected to your Pi (aka keyb, mouse, video).
And buy a good original power adapter.

6

Unfortunately, I already have original power adapter (this one)

There aren’t any unnecessary peripherals connected to my node. It is only RPi 4 (8GB), 5V cooling fan, 1TB SSD NVMe.

I’ll wait if the fan connected to 3V instead of 5V helps. Thanks for your time!

7

What other errors you see in the log? Also on the main log.
Could be also the SSD case/cable that can fail. Try to replace it, if you have another one.

These next errors I found.

Oh so you are still in IBD.
You should wait.

10

Before 5 hours IBD was finished. Now the same issue. Umbrel is unavailable through SSH, but ping to umbrel.local is ok.

If I try connect to Umbrel using SSH it doesn’t work:
kex_exchange_identification: read: Connection reset by peer

I will try to replace the USB cable and start it again.

EDIT: After starting I am not synchronized but I have to synchronize blocks again in the last 5 days.

EDIT 2: Is ok, that blockchain has 417 GB and the system has approx 150 GB? I have a feeling that my Umbrel is broken overall.

yes

I try different things with my knot all day. I tried replace USB cable but without result. I don’t know how to fix my node. Disk usage has increased by another 30GB to total about 600GB before crash. I don’t know the reason. After unplug and plug power cable was SSD usage decreased to aprox 570GB like on screen above.

My Umbrel crashed 5 times today. Ping always works properly but SSH connection is refused and access using browser through umbrel.local also doesn’t works. Data traffic of the Umbrel on router is 0 KB/s. If node became unavailable then LED on the SSD case lights up continuously for a while (a few minutes) and then will turn off.

Here is my last log after crash and reboot. But I don’t see anything special. Maybe because I don’t know exactly what to look for.

Shoul I try format SSD and mSD card and start from the beginning? Can it helps?

13

I had more or less the same problem, although i did not try to ping the inactive device. I flashed the sd with a new image, and kept the ssd. Umbrel started regularly and was running for a week and a half until it crashed again two days ago.
I just now restarted and i’m going through the logs. I hope it’s a one off.

14

Formatting is the last resort. So don’t jump straight to that until you do not know what really is going on.
You could re-format all but what if is doing the same shit, because of some kind of faulty part? You will just lose time.
First you need a good diagnose, then take drastic measures.

Looking to your logs, doesn’t seem to have software problems or data corruption.
Yes, the blockchain data was recently synced 100% but after that you still need to wait until electrs will finish the index and also compacting the database. That could take some time.
I would be patient for some hours now.
I was looking also in the hardware tab (DMESG) and couldn’t see serious problems.

Maybe @mayank can take a look at this log?

15

@gilbycoyote I already tried reflash two times but no result.

@DarthCoin I’ll wait, but I’m worried that the data may be corrupted by constantly disconnecting and reconnecting the power cable. Sometimes after plug cable I see small rollback in blockchain. I will see tomorrow.

16

if the data would be corrupted, it will be reflected into that log. But I couldn’t see any sign of that.

17

I tried to investigate yet. I tried searching the logs /var/log/syslog
There is a delay at night between the fall and the restart. Just before the fall, some errors are visible. And then subsequent start of Umbrel.
Fall: 00:49:41

I tried to watch syslog in realtime. Umbrel break down after this line
usb 2-2: Enable of device-initiated U1 failed

I spent a lot of time searching the forums and found that this problem is most likely associated with a lack of power for the SSD (as @DarthCoin wrote above). My SSD (Samsung SSD 970 EVO PLUS) has probably too much energy consumption in one moment and Umbrel fails.

I ordered new SSD with smaller consumption. I’ll see if it helps. Unfortunately, I must pass through IBD again :smiley:

19

if the data is intact and not corrupted, you can just copy the bitcoin folder from one drive to another
See the troubleshooting manual where is explained how to do it.

20

So, after few days my node works correct. I replaced my SSD and I already haven’t any issue. Node is running already 3 day at a time.
