How can I switch from multiple disks to a single disk?

data from one disk to the other, remove the configuration for the second disk, and re-start cassandra? I assume files will not have the same name and thus not be overwritten, is this the case? Does it pick it up just like that? Thanks -- *Juan Manuel Formoso *Senior Geek http://twitter.com/juanfo

I don't understand shuffle progress

n supports disabling/re-enabling (or restarting the cluster) and resuming from the last position? Or does it start over? -- *Juan Manuel Formoso *Senior Geek http://twitter.com/juanformoso http://seniorgeek.com.ar LLAP

What are the steps to go from SimpleSnitch to GossipingPropertyFileSnitch in a live cluster?

Besides making sure the datacenter name is the same in the cassandra-rackdc.properties file and the one originally created (datacenter1), what else do I have to take into account? Can I do a rolling restart or should I kill the entire cluster and then startup one at a time? -- *Juan Manuel

Just FYI, I did it with a rolling restart and everything worked great. On Wed, Sep 18, 2013 at 5:01 PM, Juan Manuel Formoso wrote: > Besides making sure the datacenter name is the same in the > cassandra-rackdc.properties file and the one originally created ( > datacenter1), what else

Re: Decomissioning a datacenter

Not forever, while I decommission the nodes I assume. What I don't understand is the wording "no longer reference" On Thu, Sep 19, 2013 at 6:17 PM, Robert Coli wrote: > On Thu, Sep 19, 2013 at 1:52 PM, Juan Manuel Formoso > wrote: > >> >> http://www.data

Decomissioning a datacenter

setting my replication_strategy so that datacenter1:0,datacenter2:N ? (assuming I'm removing datacenter1) -- *Juan Manuel Formoso *Senior Geek http://twitter.com/juanformoso http://seniorgeek.com.ar LLAP

Re: Decomissioning a datacenter

Oh, so just "datacenter2:N" then. Sorry, not a native English speaker, and also tired :) On Thu, Sep 19, 2013 at 6:57 PM, Robert Coli wrote: > On Thu, Sep 19, 2013 at 2:43 PM, Juan Manuel Formoso > wrote: > >> Not forever, while I decommission the nodes I assume. What
