DRBD is running slow on a pair of new Dell PE2950 servers, 2xQuad Core 3GHz, 16GB RAM, 6x300GB 15K SAS drives, RAID5, Centos 5.2 (2.6.18-92.1.10.el5).

It's not the GigE link between the servers: [root at ha03 ~]# netperf -t TCP_STREAM -H 2.1.1.2 TCP STREAM TEST from 0.0.0.0 (0.0.0.0) port 0 AF_INET to 2.1.1.2 (2.1.1.2) port 0 AF_INET Recv Send Send Socket Socket Message Elapsed Size Size Size Time Throughput bytes bytes bytes secs. 10^6bits/sec 87380 16384 16384 10.03 938.77 The funny thing is that when I sync'd drbd0 (which is on the same RAID array), it went much faster. The 400GB volume was done in maybe a few hours. Any ideas, please? -------------- next part -------------- An HTML attachment was scrubbed...
