Description
Hi. I have earlier followed the Raspibolt guide to set up bitcoind. I have recently migrated my entire home folder, inclugin ./bitcoin/ from one disk to another (external) drive. I have then created a softlink from that new home folder on the external drive to /home/bitcoin. I have made sure that the folder on the external drive is owned by the user bitcoin and that the user has +rwx permissions on all files and directories inside using chmod -R.
sudo chown -R bitcoin /mnt/ext/bitcoin/
with /mnt/ext/bitcoin/ being my new home directory.
When I start bitcoind using systemctl, I can't get it to run and I'm getting the following error constantly. When I login as the user bitcoin and start bitcoind in the command line, everything works fine.
The problem
When I read the logs using sudo journalctl -f -u bitcoind I get the following:
