Oracle Autonomous Linux Patching Job is Failing Due to /boot Being Full

Applies to: 

Oracle Cloud Infrastructure

Autonomous Linux 8

Symptoms 

Using Autonomous Linux 8, where the OS Management Service has been enabled. 

According to the scheduled work requests, many patch job are failing due to /boot filesystem is nearly full. 

Cause 

The user installed multiple kernel updates that lead to the boot partition being full. 

Solution  

1) Verify the size of /boot partition:

# df -h /boot 
Filesystem      Size  Used  Avail  Use% Mounted on 
/dev/sda2      1014M  1004M  10M  99%  /boot 

2) Run the following command to check installed kernels, we can see multiple kernels are installed.  

# rpm -qa | grep -E 'kernel-uek-core|kernel-core|kernel-uek|kernel' | sort
