Did you restart the node? As I can tell compactions start a few minutes after restarting. Did you see a file called $CFName.json ($CFName is your cf name) in your data directory?

Duh me. I forgot to mention I ran "nodetool compact <k> <cf>" and it was done in 45 seconds and I still had a 36G file(darn, I am usually better about putting the detail in my emailsŠI thought I added that). I also went into JMX and then did it there. I ran it again and it took 15 seconds. My script is as follows so that I know the timesŠit's too bad nodetool doesn't log times for all tools they have. If I have time, I should just do a pull request on that. #!/bin/bash date > compacttimes.txt nodetool compact databus5 nreldata >> compacttimes.txt date >> compacttimes.txt Thanks, Dean On 3/14/13 9:26 AM, "Michael Theroux" <mthero...@yahoo.com> wrote: >Hi Dean, > >I saw the same behavior when we switched from STCS to LCS on a couple of >our tables.
