1. Extend the chosen LVM on both server nodes
lvextend -L[final-size]G /dev/vg/lvm

2. Move to you primary node and check it’s status with
drbdadm state [resource] (must return “primary”)

3. Resize your primary DRBD resource and watch it’s progress via cat /proc/drbd
drbdadm resize [resource] (notes on online/offline resizing)

4. Resize your filesystem
resize2fs /dev/drbd
