So my Ssd died and i had to migrate to my Beelink from the raspberrry pi 4
my question is can i restore my lighning channels once i sync the Blockchain and download Lightning Node usingn my 24 words? even though i don’t have my ssd anymore? please help.
No, Lightning Network uses state channels implemented as 2-of-2 multisignature wallets. Your channel state lived on your old SSD. Since you don’t have that, all you can do is spin up a new node, restore your old seed phrase, and then “recover” your channels from a static channel backup (SCB) file. Hopefully you saved a static channel backup file after your last channel was established, but if you were using a recent version of Umbrel, you may also have a cloud backup that your node will automatically detect during the recovery flow (this for-sure works with the latest LND on Umbrel v1.7.3).
Recovering from SCB is a best-effort, partner-assisted activity. When you instruct your node to recover from SCB, it will load a list of your former channel partners from your SCB file. Your node will reach out to each of them with a message indicating that your mutual channel should be force-closed from their end. If a channel partner is offline, that channel closure may take a while since their node will need to be brought back up to receive the message from your new node. Note that if a channel partner’s node also dies, then your mutual channel’s funds are lost, so don’t delay if you have no way to restore your old data.
I know it hurts to lose all your channels and all of your inbound, but if you move swiftly and carefully, you will be able to recover all of your sats with just your seed phrase and your SCB file (and some patience). I wish you good luck and a RAID-1 future.
hey, you should hopefully be ok here. Umbrel’s Lightning Node app automatically backs up the SCB, so you dont necessarily need the old SSD or a backup file you saved yourself.
Once the new Umbrel is set up, install and sync Bitcoin Node, then install Lightning Node and choose the restore option instead of creating a new wallet. Enter the same 24 words and the UI should offer the most recent SCB backup it has. Just select that and continue.
The old channels won’t reopen. The recovery process asks your channel peers to close them, then the funds return to the on-chain wallet inside Lightning Node after the closes confirm and any waiting periods pass. Keep the node online, since it can take a while depending on when the peers reconnect.
So basically the 24 words recover the on-chain wallet, and Umbrel’s automatic SCB backup should help recover the channel funds. Def worth trying before assuming the sats are gone.
