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 Jan Friesse 2015-06-01 09:28:31 UTC
Description of problem:

Alain Moullé email:

So you told me that it would be modified in all documentations:
I've checked man pcs , and effectively a note has been added:

    --rrpmode allows you to set the RRP mode of the system. Currently
    only 'passive' is supported or tested  (using  'active'  is 
    not       recommended)

But it has not been modified in man corosync.conf :

       rrp_mode
              This  specifies the mode of redundant ring, which may be
none, active, or passive.  Active replication offers
              slightly lower latency from transmit to delivery in faulty
network environments but  with  less  performance.
              Passive  replication  may  nearly  double  the speed of
the totem protocol if the protocol doesn't become cpu
              bound.  The final option is none, in which case only one
network interface will be used to operate the  totem
              protocol.

              If only one interface directive is specified, none is
automatically chosen.  If multiple interface directives
              are specified, only active or passive may be chosen.

              The maximum number of interface directives that is allowed
for either modes (active or passive) is 2.

Version-Release number of selected component (if applicable):


Actual results:
RRP Active is not marked as unsupported.

Expected results:
RRP Active mode is marked as unsupported

Comment 3 Jan Friesse 2015-07-03 13:47:00 UTC
Unit test:
Man page (corosync.conf) contains note about RRP active not being supported.

Comment 4 Jaroslav Kortus 2015-09-10 08:30:15 UTC
man page quote: "Currently only 'passive' is supported or tested (using active' is  not  recommended)."

Verified in corosync-2.3.4-7.el7.x86_64
