2011/9/1 Dan Luedtke <maildanrl at googlemail.com>: > Do you use dedicated NIC for syncing? No and I was wondering the way to achive that. I guest by the parameter "bindnetaddr" in /etc/corosync/corosync.conf right? Using the address of a nice that is not the one I bridge with qemu-kvm. I was also wondering if this scenario is possible: sda6 /mnt/sheep_data1 -> sync by eth0 sdb6 /mnt/sheep_data2 -> sync by eth1 This way one disk is served by one nic. Do you think it's possible? PS: I think it's not the best Idea to have more than one sheepdog directory per node, becaus if the node goes down, much more data goes down too! A good shenario for me is 3 nodes with 2 disks each that form raid 0 md device and 2 gigbit nics. This way the sync could use the full speed of a dedicated nic (1Gbit ~ 125MB/s) without full fill the disk I/O capacity. A "normal" sata disk has 60-80 MB/s write speed, a raid 0 is double, so close to or more than max theorical nic speed. node1 (sda/sdb) -> eth0 sync -> eth1 bridge for kvm guests |
