Solution:
That error is expected thankfully , and should be an easy fix. We use parallel write for s3 multipart uploads to the cluster which is a big performance improvement. This requires a base ec level to be set for the cluster, sort of a min value that we can increase later.
First download and extract this tarball onto the csn. https://support.cloud.caringo.com/tools/caringo-support-tools.tgz
in the directory dist that it creates you’ll find a script called snmp-castor-tool.sh
You can set an ec encoding level for the cluster using the commands below. Setting the ec encoding
./snmp-castor-tool.sh -C policyECEncoding -V "2:1 anchored"
Checking the ec encoding.
./snmp-castor-tool.sh -o policyECEncoding
