[Filip Brychta (JIRA)]

    [ https://issues.jboss.org/browse/SWSQE-116?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13558339#comment-13558339 ] 

Filip Brychta commented on SWSQE-116:
-------------------------------------

Re-run installer with openshift_master_default_subdomain=prod.os.jonqe.lab.eng.bos.redhat.com and configured DNS on foreman host.
Configured persistent volumes.
Created documentation draft - https://mojo.redhat.com/docs/DOC-1167630

The selinux is enabled now (it's necessary for OS installer), we could add another node with selinux disabled and proper label just for istion pods. Selinux should be definitely enabled again when istio/kiali issue with selinux is fixed.

Next steps:
configure LDAP auth
create user for jenkins
any other suggestion?

> Currently there are following problems with our OS cluster:
> * docker on nodes is using loopback devices which is strongly discouraged for production use
> * small partition for imagefs and nodefs which is causing issues "The node was low on resource: imagefs"
> * different root passwords
> We need to:
> # investigate recommended partitioning for production OS clusters (also think about RAID versions available on each blade)
> # reinstall RHELs with recommended partitions
> # Configuring Docker Storage as described in https://docs.openshift.com/container-platform/3.9/install_config/install/host_preparation.html
> # install OS 3.9
> # create mojo documentation
