Description Brenton Leanhardt 2019-09-04 17:34:55 UTC 
Description of problem:

Many customers have been affected by Bug #1648965.  We should add a check for the appropriate kernel version as part of our upgrade preflight checks.  If it's simple enough to add to our install preflight checks we should consider that as well.

Looking at the erratas that shipped that bug fix is appears to be included in the following builds:

7.7:     kernel-3.10.0-1062.el7
7.6 EUS: kernel-3.10.0-957.27.4.el7
7.6:     kernel-3.10.0-957.27.2.el7
Comment 2 Russell Teague 2019-09-09 20:49:16 UTC 
Will be submitting an update based on feedback in https://github.com/openshift/openshift-ansible/issues/11883
Comment 3 Weihua Meng 2019-09-10 09:57:52 UTC 
need we follow doc or update doc for RHEL version?

Base OS: Red Hat Enterprise Linux (RHEL) 7.4 or later with the "Minimal" installation option and the latest packages from the Extras channel, or RHEL Atomic Host 7.4.5 or later.

Actually 3.10.0-1062.1.1.el7.x86_64 > 3.10.0-1062.el7, so it shouldn't fail here.

Fixed in openshift-ansible-3.11.145-1.git.0.61bc1df.el7

kernel 3.10.0-1062.1.1.el7.x86_64 can be installed without error.


for kernel requirement, can report correctly
