Description wanghui 2016-02-02 08:28:52 UTC

Description of problem:
The multipath disk should be recognized as /dev/mapper/* mode instead of /dev/sdx.

Version-Release number of selected component (if applicable):
rhev-hypervisor7-7.2-20160128.1.el6ev
ovirt-node-3.2.3-31.el7.noarch

How reproducible:
100%

Steps to Reproduce:
1. Install RHEV-H in TUI mode
2. Focus on boot disk page
3. Drop to shell to run#multipath -ll

Actual results:
1. After step2, the multipath disk has been recognized as /dev/sdx.
2. After step3, no output after run #multipath -ll.

Expected results:
1. The multipath disk should be recognized as /dev/mapper/* mode.

Additional info:
This issue is a regression from rhevh-7.2-20151218.1.el6ev.

Comment 1 Fabian Deutsch 2016-02-02 09:00:08 UTC

In the build logs I see:

DEBUG util.py:257:  Error:  error: argument --module: invalid choice: multipath
DEBUG util.py:257:  (available: certificates, libvirt, sanlock, sebool)

This indicates that vdsm-tool was run during the build:

(ovirt-3.6) $ git grep -- --module
recipe/common-post.ks:vdsm-tool configure --module multipath --force

But vdsm-tool is only called in the 3.6 branch.

This indicates that the recipe was not clean when the iso was built.

Hi Douglas,

The rhev-hypervisor7-7.2-20160202.1 works good to me, all the multipath disk is now recognized as /dev/mapper/* mode.
