86Gb (that's gigabits, which is 10.75GB, gigabytes) took an entire day
seems obviously too long. I would check the network bandwidth, disk IO
and CPU usage and find out what is the bottleneck.

Hi all,
Cluster of 2 DC and 24 nodes

DC2 (RF3) = 12 nodes, 16 tokens each
Adding 12 more nodes to DC1: I installed Cassandra (version is the same across
all nodes) but, after the first node added, I couldn't seem to add any further
nodes.
I check nodetool status and the newly added node is UJ. It remains this way all
day and only 86Gb of data is added to the node over the entire day (probably
not yet complete). This seems a little slow and, more than a little
inconvenient to only be able to add one node at a time - or at least one node
every 2 minutes. When the cluster was created, I timed each node from service
start to status UJ (having a UUID) and it was around 120 seconds. Of course
there was no data.
Is it possible I have some setting not correctly tuned?
Thanks
Marc
