[DRBD-user] BUG ? Proxmox 5.4, DRBD 9 Linstor 1.4

[Sébastien CHATEAU-DUTIER]

Dear All,

Since two day on Proxmox 5.4, DRBD 9 and Linstor 1.4 up to date I have 
an error for creating DRBD volume : Linstor can't see the correct 
version for all nodes : DRBD version has to be >= 9. Current DRBD 
version: 0.0.0

When adding node I have this message and after it's impossible to create 
resource :

LINSTOR ==> node create dps86810 192.168.253.4 --node-type Combined
