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
