Patch to fix
The patch is simple enough.
I don't think this can be a regression. By my examination of the code cman_tool nodes -a has always had this bug. See git commit 9098e9cc1ba4a11bd94876697728f6f44ab380ff where the feature was introduced. This is broken for at least 5.1 and 5.2. So please build against: RHEL 5.2 32 & 64 bit What ever version shipped with 5.2, I think cman-2.0.84-2.el5 Internal Status set to 'Waiting on SEG' This event sent from IssueTracker by jwilleford issue 191211 The fix hasn't been committed to git yet. I'm still waiting for ACKs This request was evaluated by Red Hat Product Management for inclusion in a Red Hat Enterprise Linux maintenance release. Product Management has requested further review of this request by Red Hat Engineering, for potential inclusion in a Red Hat Enterprise Linux Update release for currently deployed products. This request is not yet committed for inclusion in an Update release. The fix is now in the RHEL5 branch of git:

Description of problem: The command # cman_tool nodes -a Loops indefinitely showing the same node over and over again. It must be killed with ^C. Version-Release number of selected component (if applicable): 5.0 upwards. (not in stable2 or git master) How reproducible: Every time Steps to Reproduce: 1. Start up a cluster of more than one node 2. Type 'cman_tool nodes -a' Actual results: Node Sts Inc Joined Name 1 M 160824 2008-07-08 04:06:49 node-01 Addresses: 10.16.32.101 4 M 160836 2008-07-08 04:07:22 node-04 Addresses: 10.16.32.104 4 M 160836 2008-07-08 04:07:22 node-04 Addresses: 10.16.32.104 4 M 160836 2008-07-08 04:07:22 node-04 Addresses: 10.16.32.104 4 M 160836 2008-07-08 04:07:22 node-04 Addresses: 10.16.32.104 4 M 160836 2008-07-08 04:07:22 node-04 Addresses: 10.16.32.104 4 M 160836 2008-07-08 04:07:22 node-04 Addresses: 10.16.32.104 ... ad infinitum Expected results: Show me all the nodes (with addresses) and then stop. Additional info: This is a stupid variable reuse bug. "i" is used to loop round the nodes list AND the node's address list. I blame FORTRAN.
