Subject Does node add/remove requires all cluster nodes be present?
Date Tue, 01 May 2018 03:57:34 GMT
Hi All,

When a new node added, due to the even distribution of the new tokens,
the current nodes of the ring should migrate data to this new node.

So, does it requires all nodes be present? If not, then if some nodes
are down, then it will miss the data migration of those parts, how and
when to fix it? When those nodes come back?

Similarly, the node removal would migrate its data to other nodes, so
it seems that all other nodes must be present, otherwise it would lost
