You should not bootstrap with mixed cluster. First you should upgrade and
then bootstrap a new node. If you are not able to upgrade due to disk space
constraints while running upgradesstable, then
1. Reduce the number of threads for upgradesstable (--jobs parameter). By
default it is 2. You can do
Hi,
We are facing some issue in bootstrapping new node in 3.11.0 and
bootstrapping is failing.
We have two tasks here :
1. Expand the cluster (Due to disk concern and dropped mutation)
2. Upgrade the cluster from 3.11.0 to 3.11.5 because of various bugs we are
hitting in 3.11.0 .
So my question h
Hello Kevin, here are a few thoughts and things you could try:

So first thought is that this is a lot of data per node. I think the sweet
spot is around 1-2 TB / node.
I have a Cassandra(v3.7) cluster with 31 nodes, each node’s hard configuration
is 4cpu, 64GB memory, 8TB hard disk, and each node has stored about 4TB of data
now. When I joined a new node, I found that the process has not been completed
for more than a week, while the CPU load of new node and s

I can't think of any reason you'd want to do that unless you needed to grow
your cluster really quickly, and were ok with corrupting your old data.

Hi there,
I am using C* 2.0.10 and I was trying to add a new node to a
cluster(actually replace a dead node). But after added the new node some
other nodes in the cluster had a very high work-load and affected the whole
performance of the cluster.
So I am wondering is there a way to add a new

Hi,
You don't need to restart for that either. Check this out:

Hi,
As it is said in cassandra.yaml, you need to define it as # Ex: *"*
,,*"* whole list as one String.

Dear all,
I am trying to add a new node to my existing one node Cassandra. So I edited
the seeds value in the cassandra.yaml and added the ip addresses of both the
nodes. But its giving me the following error:

Check your tokens are correct using the algorithm discussed on this page

If all ok run a node tool cleanup to remove any data the nodes are no longer
responsible for. (see section on bootstrapping in the link above)
Finally, the load *may* include tom
I tried adding a new node and rebalanced the ring via nodetool move but
ending up in a weird state. Blew away all data from 2 nodes (out of 3)
and manually set tokens but its completely unbalanced.
