Modprobe drbd

[root@ha-node1 ~] # modprobe drbd

Modprobe: FATAL: Module drbd not found.

Solution:

Generally speaking, the default kernel of the system does not support this module, so update the kernel

Check the kernel version:

[root@ha-node1 ~] # uname-r

3.10.0-862.14.4.el7.x86_64

It can be updated in yum install kernel* mode.

If you want time, you can update only a few packages:

Kernel-devel

Kernel

Kernel-headers

After the update, remember to restart the operating system!

# depmod

Description: after compiling and preparing a Linux kernel load module, the command depmod must be executed before modprobe, which will generate a new modules.dep.

Execute the loading module again without reporting an error

[root@ha-node1 ~] # modprobe drbd

[root@ha-node1 ~] #

Check that it has been loaded successfully

[root@ha-node1 ~] # lsmod | grep drbd

Drbd 397041 0
