Note: This bug is displayed in read-only format because the product is no longer active in Red Hat Bugzilla.
RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

Description Chris Feist 2014-07-21 20:19:09 UTC 
Need ability to configure cluster with options similiar to RHEL 7

Need these options to work in RHEL6
--token/--join/--consensus/--miss_count_const/--fail_recv_const

Need ability to configure RRP (or warning message if not available)

Need quorum options configuration
--wait_for_all/--auto_tie_breaker/--last_man_standing/--last_man_standing_window
Comment 1 Christine Caulfield 2014-07-22 08:00:40 UTC 
There's no point in adding the new quorum options to RHEL6 as they don't exist in cman - which RHEL6 clustering still uses.
Comment 2 Tomas Jelinek 2014-12-10 14:16:17 UTC 
Created attachment 966830 [details]
proposed fix

Options not supported by cman:
--wait_for_all --auto_tie_breaker --last_man_standing --last_man_standing_window --ipv6 --token_coefficient
