Linux – CentOS: After Kernel Update system does not boot (/dev/md2 does not exist)

centosdracutlinuxlinux-kernel

after doing a kernel-update (only via yum update) my centOS 7 (64bit) does no longer boot.

I now booted into rescue-mode and tried to mount /dev/md2 – this worked fine:

Any ideas what I could do here?

Do as it suggests and make a copy of the rdsosreport.txt to /boot.

You could try booting the previous kernel - Reset the system, you should get an opportunity to select which kernel to boot, select an earlier one and see what happens.
