[jira] [Updated] (HDDS-4130) remove the 1st edition RatisServer of
SCM HA, which is copied from OM HA
[ https://issues.apache.org/jira/browse/HDDS-4130?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Glen Geng updated HDDS-4130:
----------------------------
Description: The 1st edition RatisServer of SCM HA is copied (was: The disk layout per volume is as follows:
{code:java}
../hdds/VERSION
../hdds/<<scmUuid>>/current/<<containerDir>>/<<containerID>>/metadata
../hdds/<<scmUuid>>/current/<<containerDir>>/<<containerID>>/<<dataDir>>{code}
However, after SCM-HA is enabled, a typical SCM group will consists of 3 SCMs, each of the SCMs has its own scmUuid, meanwhile share the same clusterID.
Since federation is not supported yet, only one cluster is supported now, this Jira will change scmID to clusterID for container and volume at Datanode side.
The disk layout after the change will be as follows:
{code:java}
../hdds/VERSION
../hdds/<<clusterID>>/current/<<containerDir>>/<<containerID>>/metadata
../hdds/<<clusterID>>/current/<<containerDir>>/<<containerID>>/<<dataDir>>{code})
