drbd on proxmox cluster - log - kernel-provided name 'drbd1'

I have set up some proxmox servers in cluster with drbd for replication. All work well except when I reboot servers in log I see:
This message is repeated for each drbd resource that don't have the "standard" name drbd1, drbd2 .... when I reboot the servers (never after that).

Is OK to ignore these messages because everyting work well or I should rename the drbd_pve_r1 ... to "standard" name drbd1 .... ?
Any thoughts about this?

Thanks.
