Refuting a suspect message (from: pizero) Pizero getting refuted but rejoins as per configurations

Consul
1

I have created 3 node consul servers and 1 node agent for on premise setup, and few more agent node to join.

to make the number 3 I used raspberry pi 0 , on which I had to used the consul version 1.5.3 as past this version the consul binaries are crashing with Illegal Instruct or segmentation fault error.

since this version of consul worked and all other nodes have the latest versions

Hey @vitachaos

I believe this error was fixed with our latest version of Consul. Could you elaborate more on the errors you were seeing trying to install the latest version? I’ll link the armv6 version here.

The errors could also be due to the size of the processor in a pizero, but i’m curious to hear your thoughts on that.

Its missleading, that version for pi zero would be armv6 but since pi zero is 32 bit the right one is armv5 instead.

Are there any further releases for this architecture after 1.10?
