Influx will not start

InfluxDB 2

I have potentially several largish databases on a RaspberryPi4. After any reboot or manual restart I simply get this output:

This thread helped - Influx stopped writing data - #9 by moebius - General - Node-RED Forum

Specifically this section:

I had ones the the same problem, writing data without error, but Infux Admin didn’t show the new entry’s.
Rebuilding the influx index files helped me.

# Shutdown InfluxDB
systemctl stop influxdb

# Remove all TSI index files
rm -r /var/lib/influxdb/data/*/*/*/index

# Rebuild TSI index files
su --command "influx_inspect buildtsi -datadir /var/lib/influxdb/data -waldir /var/lib/influxdb/wal" influxdb

# Start InfluxDB again
systemctl start influxdb
