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.
