Thank you very much for your answer.
Another question is about Proxmox 5 and drbd9 module.
I load drbd9 module with drbd-dkms package. But seems that it doesnt work.
Someone have answered to me that drbd module for proxmox 5 is in to-do list,
so i am looking for an alternative solution to work with drbd9 with proxmox 5.

Have someone try it? If yes which drbd-module version?

Hello,

Ι have a question about drbd cluster intialization.
How i could check if the cluster is initialized?
If "drbdmanage nodes" shows your initial node than it is ready.

I read that during the
initialization drbd creates control volumes drbd0 and drbd1.
Yes. And every node that is not created with "--satellite" also has
drbd0/drbd1 and a redundant copy of the control volume.

The node which initialize the cluster always is the  Primary node?
No. On startup (if the control volume is not set manually to Primary)
one is randomly selected as leader. If the leader fails, another is
selected as leader. The leader is the one that holds the control volume
open for writing (== Primary).
