Re: [ceph-users] Change servers of the Cluster

[Oliver Dzombic]

Hi,

if you want to be nice/free of interruption, you should consider adding
the new mon/osd to your existing cluster, let it sync, and then remove
the old mon/osd.

So this is an add/remove task, not a 1:1 replace. You will need to copy
the data from your existing harddisks anyway.

Greetings
Oliver

Hi Oliver,

Thank you for answer.

My cluster stay in VM servers. I will change to physical servers. The data
stay in storage with iscsi communications. I will map the iscsi again in
the new server.

Thank's.

[ceph-users] Change servers of the Cluster

[Daniel Takatori Ohara]

Hello,

Anyone can help me, please?

I need change the servers (OSD's and MDS) of my cluster.

I have a mini cluster with 3 OSD's, 1 MON and 1 MDS in the Ceph 0.94.1

How can i change the servers? I install the SO and ceph packages and i copy
the ceph.conf? Just it?

Thank's,
