Thank you very much for your input! Unfortunately menu option 14 didn’t help and there is no file /opt/zram/influxdb.bind exists. Maybe my influx instance is not running on zram, how can I find this out? In /opt/zram/persistence.bind there is no influxdb-related folders, but there are db4o, mapdb and rrd4j.
My /etc/ztab:
# swap alg mem_limit disk_size swap_priority page-cluster swappiness
swap lzo-rle 200M 450M 75 0 80
# dir alg mem_limit disk_size target_dir bind_dir
dir zstd 150M 350M /var/lib/openhab/persistence /persistence.bind
# log alg mem_limit disk_size target_dir bind_dir oldlog_dir
log zstd 200M 450M /var/log /log.bind
Sorry if I didn’t mention something. In my first post I wrote Platform information, I run openHAB v.3.1.0, currently it is latest stable version. I strictly followed this and this tutorials on openHAB when installing Influx. No “special” modifications to the system, I’ve started with openHAB just week ago, trying to build simple logging system, currently I have just one temperature/humidity sensor based on esp8266 (tasmota), I use UI to add bindings, channels and things. So, I mean my installation is quite simple without any “tricks”.
Any other ideas?
