I am planning on upgrading several clusters from 184.108.40.206 to 220.127.116.11. I am taking a look at this document https://www.aerospike.com/docs/operations/upgrade/aerospike/special_upgrades/4.5.1/ and have a couple of quick questions.
- According to the doc:
This could result in an imbalance of master/replica objects in such clusters.
It is not clear to me what impact this has on a cluster if there is an imbalance. I do not intend to have a mixed cluster for long periods of time (let’s say 2 days max). What gets affected due to this imbalance?
Does the imbalance self heal over time? If not, then how does one rectify this non-ideal state.
Is there a way to pause expirations/evictions while doing the maintenance? I see there is
set-disable-eviction, but not one for expirations.
