Nostr Web Client

My Umbrel is getting more or more often offline, LND and BTCPay are crashing or freezing randomly, sometimes it comes back, sometimes I have to manually restart them and LND takes a long time, 30min to more than 1h to be back online.

Anyone having similar issues? I run it on Raspi4 8GB for about 2 years. Should I do some cleanup in LND or electrum db?

I already uninstall everything not really needed, including Mempool 😥, what else can I do?

First you need to try to get the root cause of the issues.

- Check disk

- Check ram

- Check CPU use

- Check logs

LND take "a lot" of time to restart when cleanup the db.

I did try to check the logs but don't know what to look for. Disk is almost full, it's 1TB so even with minimal apps I'm 50-60GB to be full. However issues happened for some times now, before I was above 900GB, even if it stopped a couple of months before starting over again more or less regularly.

CPU and RAM are never at 100% when I check.

When the crash or freeze occur, try to look into the logs, maybe there is some clues about any issue.

Disk is a whole world, so I was talking to check not only the space, S.M.A.R.T, which stands for Self-Monitoring, Analysis, and Reporting Technology, is a system used to monitor the health of hard drives.

But... if you have a couple of dollars and don't have time, maybe it's time to migrate to a better hardware, some NUC with better performance for the next 2 or 3 years.

Downsize to the minimum that you need to cover your usual user case and focus on analyze that, less process is better to search root causes.

Go with the mini PC and Ibuntu. Follow the tutorial of 402 payment required. Apart from thenl rest server, everything is still valid.

Upside: You learn a lot about Linux and security.

Downside: you need much time.

nostr:npub126ntw5mnermmj0znhjhgdk8lh2af72sm8qfzq48umdlnhaj9kuns3le9ll DIY on an old ThinkPad have been rock solid for me.

I almost did use Start9 on a new node but their apps in the app store are way too old for me, I like to test the latest stuff, like BTCPay 2.0.3 with boltcards and the latest extensions on LNbits.

SelfBankt 1y ago

They have a Community & Beta repositories. I've become an LTS guy.

Eluc 1y ago

Ok good to know. I will see if I give it a try but now I'm well advanced in my CLI deployed node.

Remco Ros 1y ago

The services on the official registry are manually tested and verified by Start9 engineers. There's a delay between software releases and when they appear on the marketplace, but you know it has been tested very well by Start9 staff. If you like to live on the edge, you can always fork and build the service yourself. (I do this, to help out start9 testing new releases or when I really want a new feature before it's officially released).

This is no different then the "apt" repositories on linux. A lot of software have newer releases, but the official repositories are always a bit behind, because... testing, stability and security.

Same for me

Did you use their diy in the documentation? I was just looking at the two options for live-usb, I guess the x86 non free one?

Eluc 1y ago

I'm still running my node build from scratch, so far I could fix almost everything but BTCPay and LNbits as still not connect to it.

SelfBankt 1y ago

Yes, x86 non-free iso. https://github.com/Start9Labs/start-os/releases/tag/v0.3.5.1

ShiftyMcTwizz 1y ago

Thank you! I got the bootable made, and tried it out on an old laptop. It made it to the Firefox browser for install but I wasn't prepared to wipe that particular machine, so I guess I'm waiting till Monday to push the project further.

I would give up the RasPi4 and go for a miniPC (x86).

You will notice how smooth Umbrel server works.

Eluc 1y ago

Yes I did start a new node on a miniPC but didn't use Umbrel because of all these issues and didn't use Start9 because their app store is lagging a lot of versions behind (check BTCPay or LNbits apps).

I did it the hard way in CLI with some help but it's really time consuming and until I'm ready with the new one I need to keep the Umbrel running.

A new SD card, or look into booting from SSD over USB

Eluc 1y ago

I changed the SD already for a long life model. Hopefully this must not be changed every year.

Boot from SSD might help but it seams super complicated last I checked.
