Kernel

IBM Storage Scale requires the Kernel packages.

Installation of Kernel packages
  1. On all the IBM Storage Scale nodes, confirm that the output of rpm -qa |grep kernel includes the following:
    • kernel-headers
    • kernel-devel
    • kernel
    If any of the kernel RPM is missing, install it. If the kernel packages do not exist, run the following yum install command:
    yum -y install kernel kernel-headers kernel-devel
  2. Check the installed kernel rpms. Unlike HDFS, IBM Storage Scale is a kernel-level file system that integrates with the operating system. This is a critical dependency. Ensure that the environment has the matching kernel, kernel-devel, and kernel-headers. The following example uses RHEL 7.4:
    [root@c902f05x01 ~]# uname -r
3.10.0-693.11.6.el7.x86_64 <== Find kernel-devel and kernel-headers to match this

[root@c902f05x01 ~]# rpm -qa | grep kernel
kernel-tools-3.10.0-693.el7.x86_64
kernel-headers-3.10.0-693.11.6.el7.x86_64 <== kernel-headers matches
kernel-tools-libs-3.10.0-693.el7.x86_64
kernel-debuginfo-3.10.0-693.11.6.el7.x86_64
kernel-devel-3.10.0-693.11.6.el7.x86_64 <== kernel-devel matches
kernel-3.10.0-693.el7.x86_64
kernel-debuginfo-common-x86_64-3.10.0-693.11.6.el7.x86_64
kernel-3.10.0-693.11.6.el7.x86_64
kernel-devel-3.10.0-693.el7.x86_64
[root@c902f05x01 ~]#
    Warning: Kernels are updated after the original operating system installation. Ensure that the active kernel version matches the installed version of both kernel-devel and kernel-headers.
