Description Andrew Beekhof 2015-12-14 01:07:39 UTC

Description of problem:

Pacemaker gets into a loop where it tries to start the remote node connection over and over:

Good: being able to find the remote node again when it comes back
Not good: blocking other recovery in a tight loop

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

Pacemaker 1.1.13-10.el7

How reproducible:

Unclear

Comment 5 Ken Gaillot 2016-06-06 17:49:20 UTC

This will not be addressed in the 7.3 timeframe, marking for 7.4.

Comment 6 Ken Gaillot 2017-01-10 21:47:41 UTC

This will not be addressed in the 7.4 timeframe

Comment 7 Ken Gaillot 2017-10-09 17:16:24 UTC

Due to time constraints, this will not make 7.5

Comment 8 Ken Gaillot 2019-02-19 18:02:58 UTC

Dev-nack'ing until 7.8 planning can be finalized

Comment 9 RHEL Program Management 2019-02-19 18:03:08 UTC

Development Management has reviewed and declined this request. You may appeal this decision by reopening this request.

Comment 10 Ken Gaillot 2019-02-19 18:07:53 UTC

Intended dev? not dev-

Comment 11 Ken Gaillot 2020-05-06 00:30:41 UTC

Will consider for RHEL 8 only

Comment 14 Ken Gaillot 2020-10-02 21:15:21 UTC

Due to developer time constraints, this issue has been opened as an upstream bug report, and this bug will be closed. If developer time becomes available, it will be reopened.
