Check for kernel module(s) required to dump at the configured mount point

[kamalesh-babulal]

Servicereport kdump plugin should check initrd-kdump.img for the required kernel module to capture the crash dump at the configured mount point. For example, if /etc/kdump.conf is configured to dump at a local path, that's mounted on multipath disk but the dm_* module are missing from the initrd-kdump.img. Such configurations fail to capture the dump, when the initrd-kdump.img is not build with required kernel modules.

One way to teach Servicereport, to identify the missing module and fix the module dependency issue:

• Check /etc/kdump.conf for mount point
• Based on the mount point, check dracut --list-module /boot/initrd-kdump.img for the required kernel module and
• Add it using dracut --add-drivers "<module names>" /boot/initrd-kdump.img or
• Add dracut_args --add-drivers "<module name>" in /etc/kdump.conf

@kamalesh-babulal Isn't it already done by scripts that generates kdump/fadump initrd.
