Hi Everyone, We’ve noticed a few times in the last few weeks that when we’re doing backups, tar has complained with messages like this:
tar: /var/lib/cassandra/data/mars/test_instances_by_test_id-6a9440a04cc111e8878675f1041d7e1c/snapshots/backup_20180523_024502/mb-63-big-Data.db: file changed as we read it Any idea what might be causing this? We’re running Cassandra 3.0.8 on RHEL 7. Here’s rough pseudocode of our backup process: <cronjob set to fire same script at same time on all nodes> SNAPSHOT_NAME=backup_YYYMMDD_HHMMSS nodetool snapshot -t $SNAPSHOT_NAME for each keyspace - dump schema to “schema.cql" - tar -czf /file_server/backup_$HOSTNAME_$KEYSPACE_YYYYMMDD_HHMMSS.tgz schema.cql /var/lib/cassandra/data/$KEYSPACE/*/snapshots/$SNAPSHOT_NAME nodetool clearsnapshot -t $SNAPSHOT_NAME Thanks. - Max --------------------------------------------------------------------- To unsubscribe, e-mail: user-unsubscr...@cassandra.apache.org For additional commands, e-mail: user-h...@cassandra.apache.org
