Subject Re: 13k pending compaction tasks but ZERO running?
Date Thu, 14 Mar 2013 15:32:31 GMT
One more warning (which I'm sure you know, but in case others see this), nodetool compact does
a major compaction for STS, and is in general, not recommended for STS.  I only ran it on
the tables we've converted to LCS.

 Not sure why it doesn't proceed immediately (I pinged the list, but didn't get any feedback).
 However, running nodetool compact <keyspace> <table> got things moving for me.

iptables to take the ring out of the cluster for now and he is my only node still on STCS.
 In cassandra-cli, it shows LCS but on disk, I see a 36Gig file(ie. Must be STCS still). 
How can I get the 13k pending tasks to start running?
