Thanks. I add pve-headers and drbd-dkms and I can initialize the new
drbdmanage cluster.
It will be nice to include this in
https://docs.linbit.com/docs/users-guide-9.0/#ch-proxmox chapter.
But, I got a lot of messages on my syslog about PVE storage  about every
ten seconds :

In proxmox interface I have no idea of free space on my drbdpool VG.
Initialize the cluster create /dev/drbdpool/.drbdctrl_0 and
/dev/drbdpool/.drbdctrl_1.
For the moment no cluster are created for drbd and for proxmox.

/etc/drbdmanaged.cfg contain :
 [LOCAL]
storage-plugin = drbdmanage.storage.lvm_thinlv.LvmThinLv
force=1

and /etc/pve/storage.cfg :
dir: local
        path /var/lib/vz
        content iso,vztmpl,backup

drbd: drbdstorage
        content images,rootdir
        redundancy 3

Any Ideas ?
Thanks in advance

Regards, JdT
