Description Charlie Inglese 2015-12-30 22:43:33 UTC

vdsm/tool/configurators/multipath.py

Add "find_multipaths yes" to the default multipath.conf
+++ This bug was initially created as a clone of Bug #1173290 +++

Description of problem:
find_multipaths default is set to no in ../vdsm/tool/configurators/multipath.py. This creates a condition where all devices are attempted to be multipathed and creates error conditions and error messages to the console, as referenced in Bug #1182048.

Please also refer to Bug #1173290

Test version:
vdsm-python-4.17.10.1-0.el7.centos.noarch

Test steps:
1. Installed vdsm
2. Reference /etc/multipath.conf file

Actual result:
/etc/multipath.conf does not have "find_multipaths yes" in the defaults section.

Expected result:
/etc/multipath.conf has "find_multipaths yes" in the defaults section.
Comment 1 Charlie Inglese 2015-12-30 22:46:18 UTC 
Suggest adding "find_multipaths yes" above Line 43 in the ../vdsm/tool/configurators/multipath.py
Comment 2 Fabian Deutsch 2016-01-04 11:20:57 UTC 
"find_multipaths yes" is functionaliyt wise not needed anymore in RHEV-H's multipath.conf, because vdsm changes the multipath configuration to multipath any device, regardless of the number of paths.

Getting rid of the error message is another issue which is currently under investigation in bug 1182048.

Thus I'm closing this bug, please reopen if you think this is necessary.
