Dear Ceph users,
We are currently working on CEPH (RBD mode only). The technology is
currently in "preview" state in our lab. We are currently diving into
Ceph design... We know it requires at least 3 nodes (OSDs+Monitors
inside) to work properly. But we would like to know if it makes sense
to use 4 nodes ? I've heard this is not a good idea because all of the
capacity of the 4 servers won't be available ?
Someone can confirm ?
There's no problem to use 4 servers for OSD; just don't put a monitor in
one of the nodes. Always keep an odd number of monitors (3 or 5).
Monitors don't need to be in a OSD node, and in fact for medium and
large clusters it is recommended to have a dedicated node for them.
Cheers
Eneko
