[jboss-jira] [JBoss JIRA] (WFWIP-186) PVC access mode is hardcoded to ReadWriteOnce

[Jeff Mesnil (Jira)]

    [ https://issues.jboss.org/browse/WFWIP-186?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13782426#comment-13782426 ] 

Jeff Mesnil commented on WFWIP-186:
-----------------------------------

The persistent volume is mounted for the standalone/data dir that is never shared between instances.

https://kubernetes.io/docs/concepts/storage/persistent-volumes/#access-modes: "A volume can only be mounted using one access mode at a time, even if it supports many. For example, a GCEPersistentDisk can be mounted as ReadWriteOnce by a single node or ReadOnlyMany by many nodes, but not at the same time."

So we specify that the persistent volume mounted to store server data can only be accessed by a single pod (ReadWriteOnce) even though the pv could also be mounted as a shared volume (ReadWriteMany)
