Run Your Node

Stage 5 of 7

Maintain a healthy node

Routine checks are short. Safe shutdowns, storage headroom and deliberate updates prevent most avoidable failures.

Status indicators

Healthy

Synced tip is recent, peers are connected, free storage is comfortable, logs show no persistent warnings and the system is stable.

Needs attention

Sync is falling behind, storage is trending low, peer count stays at zero, updates are overdue or repeated warnings appear.

Urgent

Disk is nearly full, storage disconnects, repeated unclean shutdowns occur, database errors persist or the device overheats.

Weekly checklist

  • Confirm the latest block time is recent
  • Confirm peer connections
  • Review free disk space
  • Check the device is not overheating
  • Scan recent logs for repeated warnings

Monthly checklist

  • Review supported Bitcoin Core or umbrelOS updates
  • Confirm automatic startup still works
  • Test that the node is reachable from the intended local wallet
  • Inspect SSD health where tooling is available
  • Review firewall and remote-access settings

Update-time checklist

  1. 1

    Read official release notes

    Check compatibility, known issues and whether your current release is still supported.

  2. 2

    Back up irreplaceable data

    Back up wallet descriptors, seeds or wallet files where used, plus deliberate configuration and labels. Protect backups as secrets.

    Warning: Blockchain block files and chainstate can be downloaded and rebuilt; private keys cannot.

  3. 3

    Shut down normally

    Use Exit, stop the service normally, and wait until the process has completely ended.

  4. 4

    Install from the official source

    Download and verify the current release. Do not downgrade or delete data unless official recovery guidance specifically requires it.

  5. 5

    Verify after restart

    Check sync, peers, warnings, wallets and any connected applications.

Recovery planning

Back up

Private keys or seed material, wallet descriptors/exports, important labels, configuration you intentionally changed and any service credentials.

Re-download

Blockchain blocks, chainstate and application binaries can normally be reconstructed from the network and verified again.

Dedicated uptime

Use Ethernet, reliable cooling and power, automatic service start, enough disk reserve and controlled update windows. A UPS can reduce unclean shutdowns.
