One of our client was facing issue with OVH kernel. After rebooting the server it’s not coming up with normal kernel. <\/p>\n\n\n\n

First bring the server online with any of the working kernel.<\/p>\n\n\n\n

Once the server is online then check how many kernel’s are present on the server. You can use below command to find out the kernel.<\/p>\n\n\n\n

awk -F\\’ ‘$1==”menuentry ” {print i++ ” = “$2}’ \/etc\/grub2.cfg<\/p>\n\n\n\n

It will show list of kernels present on the server. In my case client server is RAID1. You can find the software raid version using below command.<\/p>\n\n\n\n

cat \/proc\/mdstats<\/p>\n\n\n\n

Then try compiling the kernel with raid1 module.<\/p>\n\n\n\n

dracut –mdadmconf –fstab –add=”mdraid” –add-drivers=”raid1″ -f \/boot\/initramfs-3.10.0-957.5.1.el7.x86_64.img 3.10.0-957.5.1.el7.x86_64<\/p>\n\n\n\n
