Hi, I'm only recently started playing with glusterfs. My set up consists of two servers (noriko and kumiko), each with twelve 1Tb disk, raided together in raid10. The systems have CentOS-5.5 installed, and I have installed?glusterfs-3.0.4-1 (client, common and server). I have generated the server and client files with: glusterfs-volgen --name store1 --transport tcp noriko:/mnt/raid10/ kumiko:/mnt/raid10 I then mounted the filesystem with: glusterfs --volfile=/etc/glusterfs/store1-tcp.vol /mnt/glusterfs In a naive test of the performance I tried: dd if=largeFile of=copyOfLargeFile bs=1024k oflag=sync (largeFile is about 450 M) I did this first from one client, and then from two clients simultaneously. I expected the time to be about the same for the two cases, but in contrast it took about twice the time when doing the operation simultaneously. I'm probably missing something obvious here, and would appreciate any help. Regards, /jon
