Hello Paul,
Thanks for your reply.
Now my clients will be from 140.109 (LAN, the real ip network 1Gb/s) and from 10.32 (SAN, a closed 10Gb network). Could I make this public_network to be 0.0.0.0? so mon daemon listens on both 1Gb and 10Gb network?
Or could I have
public_network = 140.109.169.0/24, 10.32.67.0/24
cluster_network = 10.32.67.0/24
does ceph allow 2 (multiple) public_network?
And I don't want to limit the client read/write speed to be 1Gb/s nics unless they don't have 10Gb nic installed. To guarantee clients read/write to osd (when they know the details of the location) they should be using the fastest nic (10Gb) when available. But other clients with only 1Gb nic will go through 140.109.0.0 (1Gb LAN) to ask mon or to read/write to osds. This is why my osds also have 1Gb and 10Gb nics with 140.109.0.0 and 10.32.0.0 networking respectively.
Cheers
Joshua

The cluster/private network is only used by the OSDs. Nothing else in ceph or its clients communicate using it. Everything other than osd to osd communication uses the public network. That includes the MONs, MDSs, clients, and anything other than an osd talking to an osd. Nothing else other than osd to osd traffic can communicate on the private/cluster network.On Sat, Sep 29, 2018, 6:43 AM Paul Emmerich <paul.emmerich@xxxxxxxx> wrote:All Ceph clients will always first connect to the mons.

further information on the cluster such as the IPs of MDS and OSDs.
This means you need to provide the mon IPs to the mount command, not
the MDS IPs. Your first command works by coincidence since
you seem to run the mons and MDS' on the same server.
