My 1 TB SSD is now full and Bitcoin Core keeps crashing. Was thing of switching to Knots anyway. Can I just plug in a 2 TB SSD and start again? Nothing else on the server to worry about.

Mine too, but I have 50 GB of free space on a 1TB drive. How full is yours? I know I need to handle this, but I thought I had some time…

Yes I thought I had a bit more time too. Mine is about the same, 50GB free space approx. I checked logs and saw lots of errors about not enough free space

mine isn’t stable, same thing , Bitcoin core keeps crashing. 50Gb is a lot, but I don’t know what I can safely delete… keep me posted

I tried pruning my Bitcoin Node… most things didn’t like that. Electrum wouldn’t work, so that basically broke everything. I’m re-indexing the whole chain, I’ll try to remember to report back… in days.

I bought a 2tb ssd and just plugged it in. Umbrel booted like it was a fresh install, new password etc, no apps. So I am now re-synching blockchain but using knots this time though.

[image] btcnym: How full is yours? Bitcoin is eating 804Gb atm + Electrum ~54Gb atm + most of the 1Tb drives are about 960Gb actually. Eazy peazy!

I have just experienced the same issue this morning.. was 650GB into blockchain download using knots… have you worked out what happened?

I’m day 2 of a likely 5-7 full resync… Fingers crossed, but no new news to report. 1TB doesn’t cut it anymore.

i found this article which seems successfull , as i am about to begin my move to a bigger drive. i just didnt want to resynch it all again! [image] Umbrel Disk Swap / Data Migration / 1TB to 2TB SSD Support and Troubleshooting Recently had to upgrade my Umbrel…
