Hi,

If you have 2 network cards (one used ina VLAN with the ceph clients and the other one in a VLAN only for the ceph servers - as recommended in the documentation) then the recovery is don via the second vlan. the one with only the ceph servers are accessible.

In the /etc/ceph/ceph.conf/ you should have the private IP class and the public IP class ... that is only if you deployed the cluster with ceph-deploy as follows:

$ ceph-deploy new <<your-server-name>> --cluster-network 10.10.10.0/24 --public-network 20.20.0.0/18

...something like that!

Hi,

my ceph cluster is recovering / rebalancing PGs since some OSDs are
marked out.

Question:
Which network is used for this task be default?
Is there any configuration for the network to be used in
//etc/ceph/ceph.conf/?

THX
