Unfortunately, I no longer have the exact message, but I'm quite confident that the IBD had completed successfully. Because the messages it showed before I rebooting are stating that the bitcoind had synchronized with the latest block once in a few minutes.

Did you perhaps import some private keys or a wallet after finishing the synchronization? Since you are running a pruned node, a rescan would require you to resync. Alternatively, did you have either the `-reindex` or `-rescan` option in config or startup opitions?

How to avoiding restart of Initial Block Download after rebooting bitcoind

# How to avoiding restart of Initial Block Download after rebooting bitcoind

(Asked by: username_0 on 2023-12-16)

I successfully completed the Initial Block Download (IBD) with bitcoind, which took about two weeks. However, after shutting down and restarting bitcoind, it seems to have initiated the IBD process again.

But my disk usage remains the same as after the initial download was completed, I guess that the synced blockchain data is still present.

So is there a way to restart bitcoind without running IBD again?

Here is the message when I start bitcoind now.

Thank you for any insights or guidance on this issue.

> **username_1**: What indication do you have that the IBD process was initiated again?

> **username_1**: And what indication do you have that IBD previously completely finished?  
> **username_0**: Unfortunately, I no longer have the exact message, but I'm quite confident that the IBD had completed successfully. Because the messages it showed before I rebooting are stating that the bitcoind had synchronized with the latest block once in a few minutes.  
> **username_2**: Did you perhaps import some private keys or a wallet after finishing the synchronization? Since you are running a pruned node, a rescan would require you to resync. Alternatively, did you have either the `-reindex` or `-rescan` option in config or startup opitions?
