2 node cluster patching, after patch we are getting version difference

[rahulbhardwaj29_87]

Hi Team, I have patch CentOS VM Hosted on Azure Cloud PF. I have patched both servers in same day & with Same Repo's.

Got approx. 36 CentOS patches difference, here I want to ask why this is So happened as well are these packages make any difference for Servers.
Could you please confirm what could be possible reason behind it.

Major difference related to Kernel:
kernel-3.10.0-1127.10.1.el7.x86_64 kernel-3.10.0-1127.el7.x86_64 ??
Please confirm both are same kernel ?

Apparently one of your 2 systems is pointing at an out of date mirror. All those packages are out of date and need to be updated. Check if you have the 'updates' repo enabled on the out of date system as, for example, kernel-3.10.0-1127.el7.x86_64 is the original kernel from the 'base' repo and kernel-3.10.0-1127.10.1.el7.x86_64 is from the 'updates' repo (also that's now out of date as 3.10.0-1127.13.1.el7 was released yesterday).

You could run these on both servers:

Code: Select all

sudo yum --enablerepo=* clean all
sudo yum repolist

Do the lists of repositories differ?
