nodetool repair fails after expansion

2013-10-04 Thread Dave Cowen
We're testing expanding a 4-node cluster into an 8-node cluster, and we keep running into issues with the repair process near the end. We're bringing up nodes 1-by-1 into the cluster, retokening nodes for an 8-node configuration, running nodetool cleanup on the nodes after each retokening, and the

Re: Increased read timeouts during rolling upgrade to C* 1.2

2013-10-04 Thread Paulo Motta
One more piece of information to help troubleshooting the issue: During the "nodetool drain" operation just before the upgrade, instead of just stopping accepting new writes, the node actually shuts itself down. This bug was also reported in this other thread: http://mail-archives.apache.org/mod_m

Increased read timeouts during rolling upgrade to C* 1.2

2013-10-04 Thread Paulo Motta
Hello, I have isolated one of our data centers to simulate a rolling restart upgrade from C* 1.1.10 to 1.2.10. We replayed our production traffic to the C* nodes during the upgrade and observed an increased number of read timeouts during the upgrade process. I executed nodetool drain before upgra

That spreadsheet doesn't take compression into account, which is very important in my case. Uncompressed, my data is going to require a petabyte of storage according to the spreadsheet. I am pretty sure I won't get that much storage to play with. The spreadsheet also shows that Cassandra waste
