unrecognized column family in logs

Hello,

We run Cassandra 2.1.13 and since last few days we're seeing below in logs occasionally. The node then becomes unresponsive to cqlsh.

ERROR [SharedPool-Worker-2] 2017-11-08 17:02:32,362 CommitLogSegment.java:441 - Attempted to write commit log entry for unrecognized column family: 2854d160-3a2f-11e6-925c-b143135bdc80

https://github.com/mariusae/cassandra/blob/master/src/java/org/apache/cassandra/db/commitlog/CommitLogSegment.java#L95

The column family has heavy writes, but it hasn't changed schema / load wise recently. How can this be troubleshooted / fixed ?

Thanks !

nodetool describecluster will show (a) if there are multiple schema
versions, and/or (b) unreachable nodes. Cheers!

 Does "nodetool describecluster" shows an actual schema disagreement?You can try "nodetool resetlocalschema" to fix the issue on the node experiencing disagreement.

 It looks like you have a schema disagreement in your cluster which you need to look into.
And you're right since that column family ID is equivalent to Friday, June 24, 2016 10:14:49 AM PDT.
Have a look at the table IDs in system.schema_columnfamilies for clues. Cheers!

It looks like you have a schema disagreement in your cluster which you need
to look into.

And you're right since that column family ID is equivalent to Friday, June
24, 2016 10:14:49 AM PDT.

Have a look at the table IDs in system.schema_columnfamilies for clues.
Cheers!
