nodetool ring question
Hi,
I have a 4 nodes cluster 1.0.3 version
This is what I get when I run nodetool ring
Address DC Rack Status State Load Owns

I have finished running repair on all 4 nodes.
I have less then 10 GB on the /var/lib/cassandra/data/ folders
My question is Why nodetool reports almost 50 GB on each node?
Thanks
Michael

Subject: Re: nodetool ring question
You can cross check the load with the SSTable Live metric for each CF in
nodetool cfstats.
Can you also double check what you are seeing on disk ? (sorry got to ask :)
)
Finally compare du -h and df -h to make sure they match. (Sure they will,
just a simple way to check disk usage makes sense).
Cheers

I have finished running repair on all 4 nodes.
I have less then 10 GB on the /var/lib/cassandra/data/ folders
My question is Why nodetool reports almost 50 GB on each node?
Thanks
Michael
Re: nodetool ring question
Posted by aaron morton <aa...@thelastpickle.com>.
You can cross check the load with the SSTable Live metric for each CF in nodetool cfstats.
Can you also double check what you are seeing on disk ? (sorry got to ask :) )
Finally compare du -h and df -h to make sure they match. (Sure they will, just a simple way to check disk usage makes sense).
Cheers

Problems Starting Cassandra Server -
Posted by Asha Subramanian <As...@hcl.com>.
I am a new user of Cassandra and want to understand the basics of Cassandra before moving to cluster installations etc..
I picked up the latest version of Cassandra from the home page 1.0.7 released on 2012/01/16. I am installing on Windows 7
I have followed all the instx for changing the Cassandra.yaml and also the environment variables.. However when I start the server, I get the following error -
What could be the problem ???

Subject: Re: nodetool ring question
There were some nodetool ring load reporting issues with early version of 1.0.X don't remember when they were fixed, but that could be your issue. Are you using compressed column families, a lot of the issues were with those.
Might update to 1.0.7.

I have finished running repair on all 4 nodes.
I have less then 10 GB on the /var/lib/cassandra/data/ folders
My question is Why nodetool reports almost 50 GB on each node?
Thanks

Re: nodetool ring question

Michael, Robin
Let us know if the reported live load is increasing and diverging from the on disk size.
If it is can you check nodetool cfstats and find an example of a particular CF where Space Used Live has diverged from the on disk size. The provide the schema for the CF and any other info that may be handy.

Good idea Jeremiah, are you using compression Michael ?
Scanning through the CF stats this jumps out.
Column Family: Attractions
SSTable count: 3
Space used (live): 27542876685
Space used (total): 1213220387
Thats 25Gb of live data but only 1.3GB total.
Otherwise want to see if a restart fixes it :) Would be interesting to know
if it's wrong from the start or drifts during streaming or compaction.

Re: nodetool ring question
Posted by aaron morton <aa...@thelastpickle.com>.
Good idea Jeremiah, are you using compression Michael ?
Scanning through the CF stats this jumps out…
Column Family: Attractions
SSTable count: 3
Space used (live): 27542876685
Space used (total): 1213220387
Thats 25Gb of live data but only 1.3GB total.
Otherwise want to see if a restart fixes it :) Would be interesting to know if it's wrong from the start or drifts during streaming or compaction.
Cheers

There were some nodetool ring load reporting issues with early version
of 1.0.X don't remember when they were fixed, but that could be your
issue. Are you using compressed column families, a lot of the issues
were with those.
Might update to 1.0.7.
