Not able to boot Gateway Server

Products

• CA API Gateway

Issue/Introduction

Server that have been running without problems , suddenly it has started to fail.

- Looks like the / file system went read only, went we tried to reboot the system didnt boot because couldn't find the kernel image.

- We generate the kernel again with : 

   dracut -f /boot/initramfs-3.10.0-1160.11.1.el7.x86_64.img 3.10.0-1160.11.1.el7.x86_64

- Now the system find the kernel but still not booting, same with the other 2 kernels available.

- The only way to boot the server is booting in "default mode"

 

 

Environment

Release : 10.0

Component : API GATEWAY

Cause

 - VMs had some underlying disk changes on the ESX side which caused the initial issue

- file system sector currupted

Resolution

Customer run fs check on the unmount file system. One of them had fixed some sectors, after that the system boot correctly.
