[DRBD-user] linstor-proxmox v7.0.0-rc.1

[Dori Seliškar]

Hi Roland,

You can disregard this report. After playing a bit more with PVE GUI I 
noticed that the graph on one of the nodes doesn't correspond to the 
values in the status. After restarting pvestatd on all nodes everything 
is working just fine. Sorry for false alarm. Keep on the good work.

Best regards,
ds
