Issue in page Blockchain Migration Step 5

[sturms]

I would like to report an issue in page https://docs.start9.com/0.3.5.x/service-guides/bitcoin/blockchain-copy

Problem

If the connection to the example-bbb.local machine is interrupted when running commands in step 5, they might not work anymore after trying to run them again. After entering a correct password it outputs permission denied error:

start9@example-bbb.local's password:
Permission denied, please try again.

Suggest a fix

Adding sudo command to the first part of the script as well:
--> sudo rsync -e "ssh -i ~/.ssh/example-bbb.key" -povgr --append-verify --rsync-path="sudo mkdir -p /embassy-data/package-data/volumes/bitcoind/data/main ; sudo rsync" ./{blocks,chainstate} start9@example-bbb.local:/embassy-data/package-data/volumes/bitcoind/data/main/

After modifying the script the blockchain migration resumed successfully.

Problem:

No production build of StartOS will accept an SSH password (by default anyway), because StartOS disables SSH password auth as a security measure, which is the point of doing steps 3 and 4 in the guide.

Suggest a fix

Step 3 has the user performing the sudo -i command, so in theory the user should still be root and able to copy the files from the /embassy-data/package-data/volumes/bitcoind/data/main/ path, so your suggested fix shouldn't actually be necessary.

All in all, I think you must have missed, or incorrectly performed the commands from step 3? Perhaps executing them one by one in the shell would help.

Hi,

Thanks for the reply. Interesting!
I tried to execute the step 3 line by line but the same happened. Hmm, maybe I just was just very unlucky but I spent the whole day trying to fix this. Also, I haven't used the rsync much in the past so I'm a newbie. Might be useful to add one paragraph in the docs to know what to do in network interruption scenarios.
