Replace Ceph node

[cheissol]

Hi,
I've replaced a cluster node after an hardware failure. I've copied the node configuration of the cluster following this tutorial https://pve.proxmox.com/wiki/Proxmox_VE_4.x_Cluster
The cluster is ok. The cluster is a 3 node cluster and there's ceph storage installed inside every node.

Now the problem is I want to resume old ceph cofiguration from the node. Is there a way ? Or I must reinstall ceph from scratch on the replaced node?

Thanks. Cheis

Hi,

the best way is to add the mon and osd new again.

Because the data on the osd are outdated and so they will rebalaced anyway.
And the mon is faster to install new.
