I have two: Intel Q6600 boxes with 4GB of RAM 8 x 750Gb (4,5TB RAID5EE, Adaptec 2820SA) 2 x 1Gbit Ethernet eth0: LAN eth1: DRBD SYNC (crosscable between machines) /dev/sda2 ~4,5TB for DRBD The problem is that, when I connect to an ftp/samba server on LAN (eth0) and I start uploading a file. Transfer rate is about 20-40MB/s about 10-15 seconds, then it starts lagging, about 4-10MB/s. Transfer-rate sleeps 0MB/s 5 seconds for example and all ftp transfers gets timeout. I have monitored eth1 with iptraf, and it doesn't sync more that 6-10MB/s while drbd state is (cs:Connected st:Primary/Secondary ds:UpToDate/UpToDate C r---). When drbd does sync while other end has been offline for a while... sync rate is about 20-25MB/s.
