YuckFou node is down hard
Posted about 1 year ago by YuckFou
NodeID = 0212fff1e1565713ba134324dcbc4eec59659c167569db6c2ef9797ee1a6e54c63
I was suddenly unable to ssh into it.
Rebooted. Twice. Still unable to ssh in.
Connected external display.
This is what I am seeing:
I have my SCB and seed words. Am going to use this opportunity to switch from Citadel to Raspiblitz.
Flashing SDHC card now.
Restoring from SCB should force close all of my existing channels.
I will reopen all channels listed on this spreadsheet ASAP: https://docs.google.com/spreadsheets/d/1XQZR3OX_b0AC1vlyR3WAsKOzzZO3_bi30ZztzO1DlQs

Suspecting pi4 now.
Have replacement pi4 in hand, different/new powersupply.
Flashing raspiblitz to different sdhc card now.
If the flash goes well, I should be booting it in the next 2 hours.

New everything; new pi4, new cables, new SDHC, and new raspiblitz software to eliminate all possibilities.
Planning on using SCB, so all existing channels will be force closed momentarily.
I will reopen all channels that I had before, and pay all rebalancing fees.

Copying of the blockchain data to the new node has begun. It will be several hours before it's done copying.

I thought it would have a new pubkey, but it looks like it will still be the original pubkey 0212fff1e1565713ba134324dcbc4eec59659c167569db6c2ef9797ee1a6e54c63. Still working on getting this new node permanently set up; static LAN IP address, mounted in a permanent location on my rack in an active-cooled Pi enclosure (whereas the last one was just dangling behind my monitor with no case, no cooling).

from the screenshots it seems that the cause might be the SD card. Have you checked it?
good luck with the transition!

The node started acting wacky days before it failed.
When it did, I quickly made an up-to-date backup of the SCB.
However, I left the node running and am positive that at least 5 very small LN transactions occurred since I did the last SCB backup. That pretty much invalidated the SCB. I did not want to take a chance of some peer running a watchtower see that I was 5000 sats short on my restore, then penalize me dearly for it.
Also the node that failed was a Citadel (https://github.com/runcitadel/citadel) and finding their node software to download is near impossible. They're going thru some major changes and rebranding, so finding the package to flash another SDHC with was taking more time than it was worth, so I gave up on that whole idea and switched over to Raspiblitz instead.
@Middle Way ₿⚡ : that idea of sending backups to a watchtower sounds like it should work... but I know little/nothing of watchtowers yet other than the theory of them. I have yet to run one myself. Also to answer your question about temp warnings; I never saw any warnings. Maybe there was one very early on when I first set it up. I moved it away from hanging over the USB strip (which gives off the tiniest amount of heat), the problem went away, so I left it as it was for it's whole lifetime (about 13-14 months before it died).

I suspect it was the power supply that was the cause.
Replaced power supply with a new one.
Now the raspiblitz node is stuck in a loop since I made a mistake of deleting one of the files it was complaining about that failed a checksum.
Opened issue on raspiblitz: https://github.com/raspiblitz/raspiblitz/issues/4230

CanaKit 3.5A Raspberry Pi 4 Power Supply (USB-C), ASIN B07TYQRXTK, ordered from Amazon.
I have heard other horror stories about using knock-off Raspberry Pi 4 power supplies, but I thought those were just unlucky people somehow. Now I'm a believer; use only genuine Raspberry Pi power supplies. The cost savings when buying a competing product from a different manufacturer is only a few dollars. This corrupted node failure, whether it was caused by the CanaKit power supply or not, has ended up costing me hundreds of dollars in open/closing channel fees, 30+ hours hours spent troubleshooting, and the end of this node's life. Lesson learned.
If you ever need to purchase another Raspberry Pi 4 power supply, do yourself a favor; spend the couple extra bucks to get a genuine Raspberry Pi product.

I'm not sure what it's doing now.
The Raspiblitz status screens still shows "Node is Syncing".
Not seeing any more new messages in /mnt/hdd/bitcoin/debug.log
I'm just going to leave it alone for a while as to not mess up anything it might be doing behind the scenes.

Bad news: Prior to the node failure I had 65,299,064 sats on the node according to the last screenshot that I had of the node's dashboard before it failed. Now it shows that I only have 60,446,879 sats. So somehow I lost 4,852,185 sats, or 0.04852185 BTC, about $1,795.64 at the current BTC price of $37007.
I see that RTL is showing 5 channels in the Pending tab;
Pending Force Closing (1)
Waiting Close (4)
None of those Pending channels make sense;
The 1 in Pending Force Closing has an on-chain closing TxID, 77b92d64026251c9404cda48e4d34654bc7266310b7a8b8d3ea626bfea601abd, and that Tx id Confirmed on-chain with 2,398 confirmations.
RTL still shows it as Pending.
Not sure what to make of that, or what I should try to do to fix it.
The other 4 Waiting Close channels are wrong also.
So something is still screwy somewhere.
I'm too tired to figure it out now. Need sleep. Will have to resume hacking away at this tomorrow.

1. Check your lnd.conf to have:
max-commit-fee-rate-anchors=100
lncli closechannel funding_txid --force

I will give that a shot momentarily.
I'm on Telegram as @YuckFouBTC.

RTL does not load.
This doesn't look good...

They don't work anymore.
Maybe something changed with the raspiblitz software so those are no longer the correct commands to use.
Giving up on it again soon.
Looks like the node has not been rebooted in 16 days;
admin@192.168.1.247:~ ₿ uptime
23:35:40 up 16 days, 12:54, 5 users, load average: 7.09, 6.49, 5.33
admin@192.168.1.247:~ ₿
But I'm not going to just go and reboot it yet.
Hmm... It should come up with a menu when ssh'ing in, not just get stuck at that "Node is Syncing" message...

I'm too tired to do anything more with this tonight. I will try to pick this up again tomorrow.
Still seeing 4 ("zombie"?) channels showing in LNDg:

I ended up enlisting the help of another (semi-famous) bitcoiner; Semisol.
Semisol has helped me in the past when I had node problems.
This time he helped me again.
As promised, I split the recovered sats with him 50/50.
I can attest that Semisol is a genuinely helpful and honest person. He is trustworthy enough to deal with delicate node recovery situations where you may need to share ssh access into the node, or share your seed phrase. Normally I would advise to never share your seed phrase with anyone, under any circumstances, but here was different; my node was down for 2+ months and I tried everything I could think of and I was only able to recover 1 of the zombie channels myself.
I ended up setting up ssh access over a Tor .onion address, and sharing all passwords (A, B, and C) and seed phrase with Semisol after I had swept all on-chain funds off of the node myself.
Semisol was able to rescue a lot of the sats that I had already considered to be lost. I believe he used chantools to do his magic. He sent them to one of his own wallets and then sent me 50% of the sats to a lightning invoice that I produced for him.
If anyone ever needs node recovery services, I would recommend that you contact Semisol directly on Nostr at npub12262qa4uhw7u8gdwlgmntqtv7aye8vdcmvszkqwgs0zchel6mz7s6cgrkj

Apologies to all of my liquidity swap partners that I had channels to before my node failed.
At first I thought I would build another node and reopen channels to all that were listed on https://docs.google.com/spreadsheets/d/1XQZR3OX_b0AC1vlyR3WAsKOzzZO3_bi30ZztzO1DlQs/edit?usp=sharing, but now things have changed. I need a break. I will not be rebuilding another node or reopening any channels anytime soon.
If/when I do set up another node, I will still attempt to reopen channels that I abandoned early here.

Middle Way ₿⚡🌊 helped me get some of the stuck sats back when I interacted with him on Telegram. He was very helpful and if you ever want to build a channel to one of the good guys, he earned my recommendation.
