Hello guys, first of all, thank you for Ceph. Such an amazon technology. Great pleasure to work with. Then to my question. I review Ceph in scope of security and need to understand how the single osd is create network port (for iptables). But i just saw some interesting thing: Some of my osds running on more then one port. for example: Ports: tcp 0 0 172.20.21.2:6902 0.0.0.0:* LISTEN 1635/ceph-osd tcp 0 0 172.20.21.2:6903 0.0.0.0:* LISTEN 1635/ceph-osd tcp 0 0 172.20.21.2:6904 0.0.0.0:* LISTEN 1635/ceph-osd ps aux|grep 1635 root 1635 1.9 0.2 1239708 172556 ? Ssl Feb23 301:34 /usr/bin/ceph-osd --cluster=ceph -i 1 -f But some doesn't have this much ports. Why do this happen ? More important to know, up to how many port will be used? In overall it looks only 3. so far 4k3nd0 -- To unsubscribe from this list: send the line "unsubscribe ceph-devel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
