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

The osd binds to the first available port in the range 6800-7100. You
can adjust the range with the config options ms_bind_port_min and
ms_bind_port_max.
