[DRBD-user] qcow2 as drbd-device ?

[fatcharly at gmx.de]

Hi,

I'm using a drbd 9.13 on CentOS 8 with pacemaker for a mysql-cluster. This cluster is running on a kvm/qemu cluster.
The virtual harddisks for the virtual mysql-nodes are qcow2 devices.
Is this really a good idea to use qcow2 as base for drbd ?
I can see that the qcow2-devices have grown larger as the drives of the virtual machines really are right now. Is this normal ?

Best regards and take care
