Hi all,
I'm in the process of testing out ceph on a small cluster. The cluster is virtually
empty with no clients, just a few OSDs. I noticed extensive disk write I/O on some nodes
and tracked them down to the ceph-mon daemon. A cursory log over 1 hour shows that each
monitor generates about 22GB worth of disk write I/O or more than 1/2TB a day. The log was
generated using iotop. It seems the 3 monitors in the cluster are doing the same thing.
Is this normal or something I should be taking a closer look at?
Cheers,
--Tri Hoang
