We tested ceph/rdma on Mellanox ConnectX-4 Lx during one year and saw no visible
benefits. But it was strange connection outages bet
and other issues.
So I'm using mellanox cards instead, but broadcom should also work.
hope it helps!

Hello there,
could you perhaps provide some more information on how (or where) this
got fixed? It doesn't seem to be fixed yet on the latest Ceph Quincy
and Reef versions, but maybe I'm mistaken. I've provided some more
context regarding this below, in case that helps.

As an option, it can be Jumbo Frames related bug. I had completely disabled JF

Hello!
IFAIK, you have to access replivated pool with default data pool pointing to ec
pool like that:
[client.user]
rbd_default_data_pool = pool.ec
Now you can access pool.rbd, but actual data will be placed on pool.ec.
Maybe it is another way to specify default data pool for using EC+Replicat

do this... what is the
best way? For the record: our cluster is now (after the upgrade) ~40% full
(400TB/1Pb) with 173 OSDs.
Cheers,
Max
some more details:
[root@ceph-node-a ~]# ceph osd lspools
1 ec42
2 cephfs_metadata
[root@ceph-node-a ~]# ceph osd pool get ec42 erasure_code_profile
era
This is good news! Thanks for the fast reply.
We will now wait for Ceph to place all objects correctly and then check if we
are happy with the setup.
Cheers
