I currently have a 1TB NFS server with an IDE boot drive (/dev/hda) and a 3ware-based RAID10 (/dev/sda) containing existing customer data. For redundancy, we have purchased a second 1TB server with a single 3ware-based RAID10 (no IDE boot drive). Data is currently replicated using rsync nightly. I'm interested in using drbd, but cannot modify the active fileserver with customer data outside of perhaps replacing the kernel. No major (or potentially destructive) modifications can be made to the primary, active server. Can I implement drdb without adversely affecting the primary fileserver? What changes would I need to make to the existing filesystems (if any) to either the primary or secondary in order to implement drbd? Thank you for your input.
