performance benchmarks looks not bad. would be interesting to see your results if you run your OSDs with bluestore.
(beginning next week, we publish 12.1 rc1 packages).

Wich steps must be done?

The plan to go into production in very short time frame

Hi,
If you disable the ceph auth you should use the firewall and block this ports on all interfaces and only allow the members ip.
disable auth will bring definitely more speed.

If you have 2 10GB nics free I would consider to separate public and private ceph network.
 
hmmm... set auth to none .... but know all vm's don't start anymore ! how to change startupcmds ?
 
You have to restart all services like osd, mon and mgr if enabled
 
i restarted the whole cluster ....

you have also edit your storage.cfg

remove the user line
 
i removed the username line, but gui still shows user:admin ...
 
can you please post the storage.cfg

I see this is only in the GUI it is already fixed update the system and is away
 
no updates avail ... if i start kvm manually

... id=admin:auth_supported=none ....
vm starts, but left tree has no update and summary state: error despite this instance is up and running :(

Sorry my fault.
We do not push it yet to the repo.
 
i will stay tuned ...

how to restart all 4 nodes with one command ? to keep ceph happy ?
 
The wiki will be updated when luminous is released.

Click to expand...
same cluster but now bluestore, Tom!
some 10% better performance!
I think with RDMA enabled we will gain another 10% to 20% speedup
but I still have no glue how to accomplish RDAM with ceph and underlying 56 Gbit Mellanox 3x cards ....
