[DRBD-user] DRDB volume with multiple source disks

[Djerk Geurts]

Hi all,

What’s the best way to expand a DRBD volume by adding disks to the nodes? I know a second volume can be created, but this is inefficient and I’ll need a volume larger than the disks and would like to use multiple disks for better throughput and IOPS.

Can one add extra disks directly to a volume or should one use LVM to add a new PV to a VG, to resize the LV resource of a DRBD volume? What would the process be, if at all possible, to do so live without risking the data?

I’m familiar with the LVM process of resizing disks, but how would DRBD be informed of the resized volume?

Thanks,
