How to remove an active node

[howhowva]

Current cluster setting is 4+0. If we need to change it to 3+1, how to re-config it without deleting current DB? I searched the online documents, but could not find any related topics.

Hi howhowva,

scaling down isn´t quite as "out-of-the-box" as scaling up - if I remember correctly, there is such a thing called "Examigration" ( roughly the process would be: create new DB instance in the same cluster, migrate data, dispose of old instance - I think the steps a rather automated , but I haven´t actually used it yet ) which you could get access to through EXA support.

Are we talking about an onPrem or a cloud-based cluster ?

Cheers,
Malte

Thanks Malte. I will reach out to EXA support. btw It's onPrem.
