Hi My problem is just start influxdb, all the resource will be occupied by influxdb, even ssh will be hard to respond. The high resource usage continues util I stop the influxdb service. What I see is when starting influxdb, it reads a lot of files, then IO and CPU is fully used, and 80% memory is…

Hi @MarcV Thanks a lot. I changed the index version to index-version = “tsi1” and restart the db, the problem still there

Hi birbird , have you converted the indexes as well with influx_inspect buildtsi ? ( must be done with the user that runs influxd )

Yes, I have done that by sudo -u influxdb bash -c 'influx_inspect buildtsi -datadir data -waldir wal'

Hi , can you do the same but with the complete path to data and wal ? probably something like this : sudo -u influxdb bash -c 'influx_inspect buildtsi -datadir /var/lib/influxdb/data -waldir /var/lib/influxdb/wal' can you check in the logfiles if you still find “op_name=tsdb_open index_version=i…

I ran buildtsi several times, the result are all “tsi1 index already exists, skipping” sudo -u influxdb bash -c 'influx_inspect buildtsi -datadir /data/influxdb/data -waldir /data/influxdb/wal' 2019-05-08T07:33:27.292985Z info Rebuilding shard {"log_id": "0FHaceUW000", "db_instance"…

Do you still have the same problem or is it better witht the tsi indexes ?

Yes, the problem is still there. Whenever start the influxdb, the whole server freeze, the only way is restarting the server

Hi @birbird,

You are using inmem indexes,
Please have a look here for example to convert to tsi indexes…
