I have two pairs of servers over the same 10 Gbit link: 1) Pair A is replicating a 1TB Sata Disk using drbd8 (Debian Jessie 8.6). 2) Pair B is replicating a 0.8TB Volume with an unterlying hardware Raid 10 consisting out of 6 SAS Disks, Stripe 16k utilizing drbd9 (Kernel 4.4 Proxmox) The server pair B should beat server pair A by at least by a factor of 3. Can't speak about drbd9 side but have you done a base benchmark of the disk throughput to actually prove that and eliminate any hardware issues or misconfiguration on the pair B? In case of a sync: * Pair A delivers a sync rate of 20 Mb/sec. * Pair B delivers a sync rate of 1 MB/sec Any ideas?
