Doc Text:	Previously, Pacemaker supported semicolon characters (";") as delimiters when parsing the pcmk_host_map string, but not when parsing the pcmk_host_list string. To ensure consistent user experience, semicolons are now supported as delimiters for parsing pcmk_host_list, as well.	Story Points:	---

Description John Ruemker 2015-03-26 15:32:13 UTC

Description of problem: Several users (including myself, a number of times) have experienced problems with pcmk_host_list due to its lack of support for semi-colon as a delimiter.  I think the confusion mostly comes from the fact that pcmk_host_map does allow it, so users that are familiar with that parameter may be inclined to use a semi-colon in both out of habit.  That's certainly what my problem was until I discovered it doesn't work, and we've had a few customers do the same thing.

We should add support for semi-colon when parsing pcmk_host_list to avoid unexpected failures to fence.  


Version-Release number of selected component (if applicable): pacemaker-1.1.12-22.el7


How reproducible: Always


Steps to Reproduce:
1. Create a stonith device with a semi-colon delimiter in pcmk_host_list="node1;node2"

2. Create a reason for a node to be fenced


Actual results:  Nodes don't see that device as being eligible to fence this node:

  Mar 26 09:50:26 rhel7-node1 stonith-ng[3392]: notice: can_fence_host_with_device: kdump can not fence (reboot) rhel7-node2.example.com: static-list


Expected results: Node is fenced
