Re: Node forgets about most of its column families
But the following nodetool repair crashes. It has to be stopped and then re-started. How did it crash ?

Re: Node forgets about most of its column families
Thanks Peter. This is 1.1.X ? Any thoughts on how recent the last schema change was ? Had the schema started in a pre 1.1X cluster? If so had their been a migration change after 1.1 upgrade?

Re: Node forgets about most of its column families
Hi Aaron, Thanks for the reply. I've recorded what we know at https://issues.apache.org/jira/browse/CASSANDRA-4583. This includes log snippets from two of the nodes from around the time. I don't know what is relevant so they've got everything that was in the system log at the time of the failure and recovery. Nodetool crashed but not returning, having nothing appear in the logs and nodetool compactionstats and nodetool netstats indicating that nothing was happening. Thanks for your time looking at this.

Node forgets about most of its column families
Hi all, I was wondering if anybody had seen the following behaviour before and how we might detect it and keep the application running. We have a 6 node cluster. It seems that one of these nodes forgot about all but one of the application column families - possibly after a restart. Then, when our application connects using Hector, it can't find any data so gives back an exception. I'm currently running nodetool repair on one of the *other* nodes which is taking a very long time to complete. (35mins and counting a load of 9MB) The logs from the failing node say: INFO [MemoryMeter:1] 2012-08-23 14:59:14,807 Memtable.java (line 213) CFS(Keyspace='system', ColumnFamily='HintsColumnFamily') liveRatio is 1.1219167666485013 (just-counted was 1.0). calculation took 28ms for 1252 columns INFO [main] 2012-08-23 14:59:14,949 CommitLogReplayer.java (line 272) Finished reading /var/lib/cassandra/commitlog/CommitLog-22654969122258 24.log INFO [main] 2012-08-23 14:59:14,950 CommitLogReplayer.java (line 103) Skipped 8216 mutations from unknown (probably removed) CF with id 1016 INFO [main] 2012-08-23 14:59:14,950 CommitLogReplayer.java (line 103) Skipped 3013 mutations from unknown (probably removed) CF with id 1017 ... and so on.
