How to restore a snapshot in cassandra 1.1

2014-10-15 Thread Ben Chobot
I was going over http://www.datastax.com/docs/1.1/backup_restore, which seems pretty clear about how to restore a snapshot. Basically, it seems the procedure is to stop your node, wipe the commit logs, move the snapshotted sstables into place, and restart. That makes sense…. so long as you only

We've also had issues with ephemeral drives in a single AZ in us-east-1, so much so that we no longer use that AZ. Though our issues tended to be obvious from instance boot - they wouldn't suddenly degrade. On Apr 28, 2013, at 2:27 PM, Alex Major wrote: > Hi Mike, > > We had issues with the ep

lots of extra bytes on disk

2013-03-28 Thread Ben Chobot
Some of my cassandra nodes in my 1.1.5 cluster show a large discrepancy between what cassandra says the SSTables should sum up to, and what df and du claim exist. During repairs, this is almost always pretty bad, but post-repair compactions tend to bring those numbers to within a few percent of

I've got a 1.1.5 cluster, and a few weeks ago I removed some nodes from it. (I was trying to upgrade nodes from AWS' large to xlarge, and for some reason that made sense at the time, it seemed better to double my nodes and then decommission the smaller ones, rather than to simply rebuild the exi

We use cassandra on ephemeral drives. Yes, that means we need more nodes to hold more data, but doesn't that play into cassandra's strengths? It sounds like you're trying to vertically scale your cassandra cluster. On Jan 16, 2013, at 12:42 PM, Marcelo Elias Del Valle wrote: > Hello, > >I
