[Filip Brychta (JIRA)]

    [ https://issues.jboss.org/browse/SWSQE-116?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13556607#comment-13556607 ] 

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

On a call we agreed to install the new prod cluster from scratch on b20 and another blade which can be removed form old prod cluster. Old prod cluster can be still up with 2 nodes until we have new one.

> 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
