Re: Change the IP of a live node
It also looks like you changed your topology by altering rack from r1 to RAC1. Shouldn't effect this issue but something to get consistent.

Re: Change the IP of a live node
This was a network problem at our side after all which we fixed. Cassandra was blocking connections between 192.168.xxx <-> 10.179.xxx on port 7000 On Wed, Mar 15, 2017 at 2:47 PM, Ryan Svihla <r...@foundev.pro> wrote: > I've actually changed the ip address quite a bit (gossip complains on > startup and happily picks up the new address), I think this maybe easier > such as..can those ip addresses route to one another ? > > As in can the first node with 192.168.xx.xx hit the node with > 10.179.xx.xx on that interface? > > On Wed, Mar 15, 2017 at 9:37 AM, kurt greaves <k...@instaclustr.com> > wrote: > >> Cassandra uses the IP address for more or less everything.

Re: Change the IP of a live node
I've actually changed the ip address quite a bit (gossip complains on startup and happily picks up the new address), I think this maybe easier such as..can those ip addresses route to one another ? As in can the first node with 192.168.xx.xx hit the node with 10.179.xx.xx on that interface?

Re: Change the IP of a live node
Cassandra uses the IP address for more or less everything. It's possible to change it through some hackery however probably not a great idea. The nodes system tables will still reference the old IP which is likely your problem here.

Re: Change the IP of a live node
To give a complete picture, my node has actually two network interfaces: eth0 for 192.168.xx.xx and eth1 for 10.179.xx.xx On Tue, Mar 14, 2017 at 7:46 PM, George Sigletos <sigle...@textkernel.nl> wrote: > Hello, > > I am trying to change the IP of a live node (I am not replacing a dead > one). > > So I stop the service on my node (not a seed node), I change the IP from > 192.168.xx.xx to 10.179.xx.xx, and modify "listen_address" and > "rpc_address" in the cassandra.yaml, while I also set auto_bootstrap: > false.

Change the IP of a live node
Hello, I am trying to change the IP of a live node (I am not replacing a dead one). So I stop the service on my node (not a seed node), I change the IP from 192.168.xx.xx to 10.179.xx.xx, and modify "listen_address" and "rpc_address" in the cassandra.yaml, while I also set auto_bootstrap: false. Then I restart but it fails to see the rest of the cluster: Datacenter: DC1 === Status=Up/Down |/ State=Normal/Leaving/Joining/Moving -- AddressLoad Tokens OwnsHost ID Rack DN 192.168.xx.xx ? 256 ? 241f3002-8f89-4433-a521-4fa4b070b704 r1 UN 10.179.xx.xx 3.45 TB256 ? 3b07df3b-683b-4e2d-b307-3c48190c8f1c RAC1 DN 192.168.xx.xx ? 256 ? 19636f1e-9417-4354-8364-6617b8d3d20b r1 DN 192.168.xx.xx? 256 ? 9c65c71c-f5dd-4267-af9e-a20881cf3d48 r1 DN 192.168.xx.xx ? 256 ? ee75219f-0f2c-4be0-bd6d-038315212728 r1 Am I doing anything wrong? Thanks in advance Kind regards, George
