This package provides an updated DRBD driver, version 8.4.1, and is kABI compatible with all kernels from 6.0 (kernel-2.6.32-71.el6) upwards.
It is built to depend upon the specific ABI provided by a range of releases of the same variant of the Linux kernel and not on any one specific build.

You may update your system by:

Once the package has been updated, remember to unload the older driver version from the kernel by restarting your DRBD resources and reloading the DRBD driver.
