Description | This article describes how to clean up the /boot directory in CentOS, RHEL or Rocky Linux 8 and up |
Scope | FortiSOAR with CentOS, RHEL, Rocky Linux 8+. |
Solution |
To free space in /boot while upgrading the FortiSOAR™ system running on Rocky Linux 8 or up, follow these steps:
1) Check the current kernel being used:
sudo uname -sr
2) List all kernels installed on the system:
sudo rpm -q kernel
3) Delete old kernels and only leave <X> number of kernels:
sudo dnf remove --oldinstallonly --setopt installonly_limit=<X> kernel
Note: <X> can be set to 1, 2, 3 or other numeric values. Carefully check the running kernel in step 2 and any other kernels used before running this command. Alternatively, use the following command to delete kernels one by one:
rpm -e <kernel_name>
Kernel names can be obtained through step 2. |
