Re: PostgreSQL - HA Cluster / Etcd Issue

Hi there, 

Etcd database should be extended from 2 gb to 8gb. On the other hand, you can use defrag or again created the etcd db.

Have a nice day,

Hello,

In my database architecture, I use Etcd, Patroni, HAProxy, and Keepalived.

Although many things in this architecture work as expected, Etcd encounters the error "memberID:5960773920904691185 alarm:NOSPACE" once every 2 or 3 months. The root cause is that the database size reaches the specified limit and Etcd does not clean it up through rotation. I am aware of this, but despite reviewing the maintenance documentation, I could not find the most appropriate parameter values for this rotation. I am sharing an example of my own Etcd configuration below. I kindly ask you to share your experience on this matter. I am kinda stuck on this issue.

In particular, is it possible to schedule the parameter that performs this cleanup with a time setting? For example, can I tell it to run the compact operation at around 01:00 AM?

Best regards.
