Command for Reindex Blockchain

My Umbrel has been out for over a week now. First the update deleted the SSD, now everything is new and now it stops when the blockchain backup is imported.

What is the command to get to the container and recover BTC individually with “-reindex”?

To reindex block umbrel, you can follow these steps:

  • Stop the Umbrel service to prevent any further writes to the database.
  • Copy only the blocks and chainstate files from your full node to the Umbrel node. Do not copy the indexes, as this can cause conflicts.
  • Run the command bitcoind --reindex to start the reindexing process. This will rebuild the block index and recreate the chainstate.

Alternatively, if you suspect corruption of the chainstate only, you can use the command bitcoind --reindex-chainstate instead. This will recreate the chainstate without rebuilding the block index.

Note that running bitcoind --reindex on a pruned node will delete all blockchain data and start from scratch, so use this option with caution.
