[DRBD-user] linstor-proxmox v6.0.0-rc.1

[Dori Seliškar]

Hi Roland,

may I ask if this issue 
(https://github.com/LINBIT/linstor-proxmox/issues/39) is in focus again. 
Having multiple SPs in RG is a must when using one SP per disk. Or is 
there another way?

... and feedback for RC1: basic tests - disk create/migrate/delete all work.

Best regards
Dori
