DRBDmanage has been replaced by LINSTOR !
To find out more about LINSTOR, check out the following blog articles:

Thank you and have a good read!
In the last blog post about DRBDmanage we mentioned
Initial setup is a bit involved (see the README)
… with the new release, this is no longer true!
All that’s needed is now one command to initialize a new DRBDmanage control volume:
nodeA# drbdmanage init «local-ip-address» You are going to initalize a new drbdmanage cluster. CAUTION! Note that: * Any previous drbdmanage cluster information may be removed * Any remaining resources managed by a previous drbdmanage installation that still exist on this system will no longer be managed by drbdmanage Confirm: yes/no:
Acknowledging that question will (still) print a fair bit of data, ie. the output of the commands that are run in the background; if everything works, you’ll get a freshly initialized DRBDmanage control volume, with the current node already registered.
Well, a single node is boring … let’s add further nodes!
nodeA# drbdmanage new-node «nodeB» «its-ip-address» Join command for node nodeB: drbdmanage join some arguments ....
Now you copy and paste the one command line on the new node:
nodeB# drbdmanage join «arguments as above....» You are going to join an existing drbdmanage cluster. CAUTION! Note that: ...
yes and enter – and you’re done! Every further node is just one command on the existing cluster, which will give you the command line to use on the to-be-added node.
So, another major point is fixed … there are a few more things to be done, of course, but that was a big step (in the right direction) 😉
