Disclaimer: Having some linux permissions issues, but it is related to setting up a Bitcoin Node, and an Electrum Server; if there’s a better place to post this, please lmk!.
I’ve been following the RaspiBolt guide in order to setup a Bitcoin Node, an Electrum Server (electrs). I’m doing this in Ubuntu Server 24.04.1 LTS.
In the guide, the OS is booted from an external hard drive; I’m booting from the Pi 5’s micro SSD card; I have the entire Bitcoin blockchain AND the electrs indexes stored in a mounted SSD
In the Bitcoin client section, the guide has you create a user and gives it access to run the bitcoin daemon. Later, it has you setup a service so that the bitcoin daemon automatically starts when the machine starts. By adding an entry in /etc/fstab, I’ve managed to get the external drive to be mounted when the machine starts, and I’m mounting it with the bitcoin user both as user and group owner; the service works just as expected.
However, I’m not having the same luck with the electr service the guide also has you setup. When I try starting electrs as the electrs user, the server crashes because it doesn’t have read/write permissions to the folder in the external drive where the electrs db is stored.
What might be a good solution for this? Is there a way to mount the drive with access to multiple users? The electrs user IS in the bitcoin group, so I thought that should have sufficed to access the mounted drive?
