Re: layer3 network

[Luis Periquito <luis.periquito@xxxxxxxxx>]

If, like me, you have several different networks, or they overlap for whatever reason, I just have the options:

mon addr = IP:port

osd addr = IP

in the relevant sections. However I use puppet to deploy ceph, and all files are "manually" created.

So it becomes something like this:

[mon.mon1]
  host = mon1
  mon addr = x.y.z.a:6789
  mon data = "">[osd.0]
  host = dskh1
  osd addr = x.y.z.a
  osd data = "">  osd journal = /var/lib/ceph/osd/journal/osd-0
  keyring = /var/lib/ceph/osd/osd-0/keyring
  osd max backfills = 1
  osd recovery max active = 1
  osd recovery op priority = 1
  osd client op priority = 63
  osd disk thread ioprio class = idle
  osd disk thread ioprio priority = 7

[osd.1]
....

necessarily the host and addr parts are correct in our environment.

Do your public/cluster networks overlap the physical connection IP's? From what I understand Ceph binds to the interface whose IP
lies within the range specified in the conf file.

So for example if public addr = 192.168.1.0/24

Then your loopback should be in that range, but you must make sure the physical nics lie outside this range.

I'm following this with interest as I am about to deploy something very similar.
