3. Insert the TF card into Raspberry Pi, connect the network cable to the notebook, and turn on the power. Then open the Windows command line tool and enter arp-;

blocks on the two Raspberry Pi do not necessarily need the same name or path name, but it is no harm to set them to the same value.
Configure the "Block" path, install the glusterfs-server software package, confirm that both Raspberry Pi are working properly, and then log on to the

Raspberry Pi backup and Raspberry Pi backup
We strongly recommend that you regularly back up important files. Backup is usually not limited to user files, but also configuration files, databases, installed software, settings, and even system snapshots.
Here we will guide you through some backup technologies to back up

after the first two steps our Raspberry Pi has worked normally, but before actually using it to develop some column configuration and software installation, so that the development will be handy, below we introduce the common software and services1. Configuration options:The first time a Raspberry Pi is used, a simple

immediately switches to another record. The switching efficiency is faster than that of the traditional heartbeat line-Robin Request Host.
So add two IP addresses of your Raspberry Pi cluster to the DNS server you are using, and then try the dig command, just as I used above, you should also be able to get two IP addresses.
When you set two A records for the same domain name, this cluster can provide Fault
