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 of problem:
The sample file "/usr/share/doc/device-mapper-multipath-0.4.9/multipath.conf"
contains a deprecated tag in the defaults section...
        #defaults {                                                     
        #       udev_dir                /dev                            
        #       polling_interval        10                              
====>   #       selector                "round-robin 0"  <=======       

In RHEL6 I beleve it should be "path_selector" instead. The following error results when using this configuration.

"[root@rhev-h4 ~]# multipath
May 31 14:35:17 | multipath.conf line 29, invalid keyword: selector"

Changing this to path_selector as per the man page solves this.
I had a customer run into this problem when using the sample file
as a basis for a new configuration.

Version-Release number of selected component (if applicable):
device-mapper-multipath-0.4.9-46.el6_2.2.x86_64



How reproducible:
Always


Steps to Reproduce:
1.copy /usr/share/doc/device-mapper-multipath-0.4.9/multipath.conf to /etc
2.Uncomment defaults section 
3.run "multipath command"
  
Actual results:


Expected results:
