Issue while setting up DRBD

Hi Folks,

I am setting up DRBD on PMX 2.2 and getting below errors. Any clue how to update DRBD tools

root@pmx01:/opt/drbd/drbd-8.3# drbdadm -- --overwrite-data-of-peer primary r0
DRBD module version: 8.3.10
userland version: 8.3.7
you should upgrade your drbd tools!

Note: checking out 'drbd-8.3.10'.


You are in 'detached HEAD' state. You can look around, make experimental
changes and commit them, and you can discard any commits you make in this
state without impacting any branches by performing another checkout.


If you want to create a new branch to retain commits you create, you may
do so (now or later) by using -b with the checkout command again. Example:


git checkout -b new_branch_name


HEAD is now at 5c0b046... Preparing 8.3.10
