I have one more question with regard to mentioned kernel update to
2.6.18-308.4.1.el5 :
in extras repo there is a package available
kmod-drbd83
8.3.12
This package provides the drbd83 kernel modules built for the Linux
: kernel 2.6.18-274.17.1.el5 for the i686 family of processors.
We currently have installed kmod-drbd83:
8.3.8
This package provides the drbd83 kernel modules built for the Linux
: kernel 2.6.18-194.el5 for the i686 family of processors.
Should kmod-drbd83 version match current kernel version (from package
description) or should kmod-drbd83 in version 8.3.8 be installed if we are
using drbd83-8.3.8-1.el5.centos ?
Best regards,
Rafal.
