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 !
Regards,
Hemant Surale.

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 root@atom0:~# Wido > > Regards, > Hemant Surale. > -- > To unsubscribe from this list: send the line "unsubscribe ceph-devel" in > the body of a message to majordomo@vger.kernel.org > More majordomo info at http://vger.kernel.org/majordomo-info.html > ^ permalink raw reply [flat|nested] 5+ messages in thread

That means, every object stored in the cluster will be stored twice. It is NOT object + 2, no it's object * 2.
