Hi all,
I have a 2-node cluster running cassandra 2.1.18.
One of the nodes has run out of disk space and died - almost all of it
shows up as occupied by size_estimates CF.
Out of 296GiB, 288GiB shows up as consumed by size_estimates in 'du -sh'
output.
This is while the other node is chugging alo
napshots? What files exist there that are taking

Thanks a lot, Chris.
Will try it today/tomorrow and update here.
Thanks,

It worked as advertised. :)
Thanks a lot, Chris.

Hi all,
We currently have a cluster in GCE for one of the customers.
They want it to be migrated to AWS.
I have setup one node in AWS to join into the cluster by following:
https://docs.datastax.com/en/cassandra/2.1/cassandra/operations/ops_add_dc_to_cluster_t.html
Will add more nodes once the f
nt regions - GCE setup is in us-east while AWS setup
is in Asia-south (Mumbai)
Thanks,
Kunal

In the AWS instance, I had added 'auto_bootstrap: false' - the doc says we
need to do "nodetool rebuild" and hence no automatic bootstrapping.
But, haven't gotten to that step yet.

No, this is a different cluster.

Kunal,
Is this the GCE cluster you are speaking of in the “Adding new DC?” thread?

Hi all,
We have a 3-node cassandra cluster with incremental backup set to true.
Each node has 1TB data volume that stores cassandra data.
The load in the output of 'nodetool status' comes up at around 260GB each
node.
All our keyspaces use replication factor = 3.
However, the df output shows the
backups?
This is my first production deployment - so, still trying to learn.
Thanks,
Kunal

Hi all,
We have a CF that's grown too large - it's not getting actively used in the
app right now.
The on-disk size of the . directory is ~407GB and I have only ~40GB
free left on the disk.
I understand that if I trigger a TRUNCATE on this CF, cassandra will try to
take snapshot.
My question:

Hi,
I have a 2 node setup on Azure (east us region) running Ubuntu server
14.04LTS.
Both nodes have 8GB RAM.
One of the nodes (seed node) died with OOM - so, I am trying to add a
replacement node with same configuration.
The problem is this new node also keeps dying with OOM - I've restarted the
Forgot to mention: the data size is not that big - it's barely 10GB in all.
