Description

Based on further customer input RHEL PM has decided to modify the proposed initial split-site (stretched) cluster configuration for QE to be a 2X2 cluster where the cluster will be stretched between two sites each having a maximum of two nodes. This configuration shall hold irrespective of the latency between the sites. The membership list should be configured so that the Totem token does not bounce back and forth the high latency link, but crosses it minimally. (i.e. nodes 1-2 on SiteA and 3-4 on SiteB, meaning token only crosses high latency link between nodes 2 and 3 and between nodes 4 and 1) This request was evaluated by Red Hat Product Management for inclusion in the current release of Red Hat Enterprise Linux. Because the affected component is not scheduled to be updated in the current release, Red Hat is unfortunately unable to address this request at this time. Red Hat invites you to ask your support representative to propose this request, if appropriate and relevant, in the next release of Red Hat Enterprise Linux. This request was erroneously denied for the current release of Red Hat Enterprise Linux. The error has been fixed and this request has been re-proposed for the current release. This enhancement request was evaluated by Red Hat Product Management for inclusion a Red Hat Enterprise Linux maintenance release. Red Hat does not currently plan to provide this enhanced functionality in a Red Hat Enterprise Linux update for currently deployed products. With the goal of minimizing risk of change for deployed systems, and in response to customer and partner requirements, Red Hat takes a conservative approach when evaluating enhancements for inclusion in maintenance updates for currently deployed products. The primary objectives of update releases are to enable new hardware platform support and to resolve critical defects. For more information on Red Hat Enterprise Linux maintenance policies, please consult: https://access.redhat.com/support/policy/updates/errata/ Red Hat values your feedback and will take this enhancement request into consideration for future major releases of Red Hat Enterprise Linux. |
