Subject Re: New nodes won't bootstrap on .66
Date Wed, 27 Oct 2010 09:40:18 GMT
Hi Aaron,
Thanks for your reply.

We still haven't solved this unfortunately.

How did you start the bootstrap for the .18 node ?


Standard way: we set "AutoBootstrap" to true and added all the servers from
the working ring as seeds.


> Was it the .18 or the .17 node you tried to add


We first tried adding .17, it streamed for a while, took on a 50GB of load,
stopped streaming but then didn't enter into the ring.  We left it for a few
days to see if it would come in, but no luck.  After that we did
 decommission and  removeToken ( in that order) operations.
Since we couldn't get .17 in we tried again with .18.  Before doing so we
increased the RpcTimeoutInMillis from 1000, to 10000 having read that this
may cause the problem of nodes not entering into the ring.   It's been going
since friday and still, like .17, won't come into the ring.

Does it have a token in the config or did you use nodetool move to set it

No we didn't manually set the token in the config, rather we were relaying
on the token to be assigned durring bootstrap from the RandomPartitioner.

Again thanks for the help.

Dimitry.
