Hello
Bonding and iscsi are not a best practice architecture. Multipath is,
however I can attest to problems with the multipathd and debian.
In any case, what you should try to do and check is:
1) Use two vlans, one for each ethernet port, with different ip
address space. Your initiators on the

It is worth asking - why do you want to have two interfaces?
If you have 1Gbps interfaces and this is a bandwidth requirement then
10Gbps cards and switches are very cheap these days.

Hi ,
I have created a ceph cluster on centos 7 Servers and it is working fine
with tcp and able to run all benchmarks.
Now want to check the same with rdma and I followed the below link to

yes it is cache, moreover what are these whiteouts? and when does this
mismatch occur.

Hi Greg,
Firstly, many thanks for your advice.
I'm perplexed as to why the crush map is upset; the host names look the
same, each node has a fixed IP on a single bond0 interface.
Perhaps the problems were an artefact of having "nodown" set?
As you suggested, I've unset "osd nodown" and am letti
Well, ok, I moved second address into different subnet
(192.168.201.231/24) and also reflected that in 'hosts' file
But that did not help much :

Are your firewall ports open for rbd-target-api? Is the process
running on the other host? If you run "gwcli -d" and try to add the
second gateway, what messages do you see?

Ok, I looked into Python sources of ceph-iscsi-{cli,config} and
found that per-host configuration sections use short host name
(returned by this_host() function) as their primary key.
So I can't trick gwcli with alternative host name like p10s2

You can't have a server with both SSDs and HDDs in this setup because you
can't write a crush rule that is able to pick n distinct servers when also
specifying different device classes.
A crush rule for this looks like this:
step take default class=ssd
step choose firstn 1 type host
emit
step take
