Re: "Not enough replicas available for query" after reboot

Yes, all three nodes see all three nodes as UN. Also, connecting from a local Cassandra machine using cqlsh, I can run the same query just fine (with QUORUM consistency level). On 4 February 2016 at 21:02, Robert Coli <rc...@eventbrite.com> wrote: > On Thu, Feb 4, 2016 at 12:53 PM

"Not enough replicas available for query" after reboot

Hi, My cluster was running fine. I rebooted all three nodes (one by one), and now all nodes are back up and running. "nodetool status" shows UP for all three nodes on all three nodes: -- AddressLoad Tokens OwnsHost ID Rack UN xx.xx.xx.xx331.84 GB 1 ?

Re-bootstrap node after disk failure

Hi, What is the process to re-bootstrap a node after hard drive failure (Cassandra 2.1.3)? This is the same node as previously, but the data folder has been wiped, and I would like to re-bootstrap it from the data stored on the other nodes of the cluster (I have RF=3). I am not using vnodes.

Re: Out of Memory Error While Opening SSTables on Startup

I already experienced the same problem (hundreds of thousands of SSTables) with Cassandra 2.1.2. It seems to appear when running an incremental repair while there is a medium to high insert load on the cluster. The repair goes in a bad state and starts creating way more SSTables than it should

Re: How to deal with too many sstables

Did you run incremental repair? Incremental repair is broken in 2.1 and tends to create way too many SSTables. On 2 February 2015 at 18:05, 曹志富 cao.zh...@gmail.com wrote: Hi,all: I have 18 nodes C* cluster with cassandra2.1.2.Some nodes have aboud 40,000+ sstables. my compaction strategy is

Re: Does nodetool repair stop the node to answer requests ?

I don't think you can do nodetool repair on a single node cluster. Still, one day or another you'll have to reboot your server, at which point your cluster will be down. If you want high availability, you should use a 3 nodes cluster with RF = 3. On 22 January 2015 at 18:10, Robert Coli

How do replica become out of sync

Hi, When writing to Cassandra using CL = Quorum (or anything less than ALL), is it correct to say that Cassandra tries to write to all the replica, but only waits for Quorum? If so, what can cause some replica to become out of sync when they're all online? Thanks Flavien

Compaction failing to trigger

Hi, I am using Size Tier Compaction (Cassandra 2.1.2). Minor compaction is not triggering even though it should. See the SSTables on disk: http://pastebin.com/PSwZ5mrT You can see that we have 41 SSTable between 60MB and 85MB, which should trigger compaction unless I am missing something. Is
