[pve-devel] pveceph : disabling cephx auth + debug when we init ceph.conf ?

[Alexandre DERUMIER]

Hi,

to have good performance with ceph, they are 2 boosts possible:
Maybe we could add them as command option in ceph init ?


1)disabling cephx auth.

[global]

auth_cluster_required = none
auth_service_required = none
auth_client_required = none



- I always disabling them on my cluster, it's give me around 20% extra boost on 4k iops.

and don't require to put the key in /etc/pve/priv/ceph/.

I running all my cluster like this since years.

Of course, for security, user need to have their ceph cluster on a private network.



2) disable debug log,

give me another 15-20% extra boost
