Applies to:

Big Data Appliance Integrated Software - Version 4.5.0 and later
Linux x86-64

Symptoms

Throughout the note, <version>. is the kernel version which is required for cluster nodes.

One node of a BDA OL6 cluster can only boot into rescue mode. Booting into the OS panics.

1. In rescue mode it is observed that the file: /system_boot/initramfs-<version>.el6uek.x86_64.img is much smaller than the file on healthy nodes of the cluster which successfully boot into the OS.

For example:

a) On a healthy node:

2. The other kernel images are found to have the same size as on the rest of the cluster.

For example these have the same size as the rest of the cluster. It is not necessary for initrd-<version>.el6uek.x86_64kdump.img to be present. It is created on boot, and if no boot has happened it will not be there.

  • /boot/config-<version>.el6uek.x86_64
  • /boot/symvers-<version>.el6uek.x86_64.gz
  • /boot/System.map-<version>.el6uek.x86_64
  • /boot/vmlinuz-<version>.el6uek.x86_64
  • /boot/initrd-<version>.el6uek.x86_64kdump.img
