Hello. Im looking for proper way for the nic bonding for ceph. I was using the bonding driver with default settings ad_select=stable(default) and hash algorithm layer2. With this settings osds are using only one port and lacp only usefull for different nodes because layer2 hash algorithm using Mac. I've changed ad_select to bandwitdh and both nic is in use now but layer2 hash prevents dual nic usage for between two nodes (because layer2 using only Mac ). People advice using layer2+3 for best performance but it has no effect on osds because mac and ip is the same. I've tried layer3+4 to split by ports instead mac and it works. But i dont know what will the effect and also my switch is layer2. With "iperf -Parallel 2" now i can reach 19gbit on 2x 10gbit nics. I think there is no way to use both nic without parallel Usage with different ports. If I use same port and too many process I can only use one port at a time. What settings are you using? What is the best for ceph? _______________________________________________ ceph-users mailing list -- ceph-users@xxxxxxx To unsubscribe send an email to ceph-users-leave@xxxxxxx
