Hi Wido , Community ,
if we use number =2
in cmd as follows
"ceph osd pool set <poolname> size <#no>"
does it means for perticular Object we have 2 replica Or total 2
copies in cluster?
That will set replication to "2". That means, every object stored in the
cluster will be stored twice.
Sorry, I have to correct myself there.
Every object in that (RADOS) POOL is stored twice, not the cluster. This
is a pool specific setting, not cluster-wide.
Wido
It is NOT object + 2, no it's object * 2.

Hi Community ,
I want to trace the data transfer rates occurring between
osds while injecting data into ceph cluster. Can you please tell me
what ports should I monitor or keep track of?
Thanks !
OSDs start binding from port 6800 and counting up from there.
For example, a machine with 4 OSDs running:
root@atom0:~# netstat -nap|grep LISTEN|grep -E ^tcp|grep ceph-osd
tcp6 0 0 :::6800 :::* LISTEN
24329/ceph-osd
tcp6 0 0 :::6801 :::* LISTEN
24329/ceph-osd
tcp6 0 0 :::6802 :::* LISTEN
24329/ceph-osd
tcp6 0 0 :::6803 :::* LISTEN
24596/ceph-osd
tcp6 0 0 :::6804 :::* LISTEN
24596/ceph-osd
tcp6 0 0 :::6805 :::* LISTEN
24596/ceph-osd
tcp6 0 0 :::6806 :::* LISTEN
25316/ceph-osd
tcp6 0 0 :::6807 :::* LISTEN
25316/ceph-osd
tcp6 0 0 :::6808 :::* LISTEN
25316/ceph-osd
tcp6 0 0 :::6809 :::* LISTEN
25839/ceph-osd
tcp6 0 0 :::6810 :::* LISTEN
25839/ceph-osd
tcp6 0 0 :::6811 :::* LISTEN
25839/ceph-osd
