Influx db - data lost after reboot!?

[rossko57]

Have a look part way through this thread, to check (so far this is all only speculation)

OH 3.1.0 InfluxDB stopped working after update to 1.8.7-1

As far as I understand you will see devices like /dev/zram* in case zram is enabled and used. Besides that you will have entries in /etc/ztab which describe how different directories are managed/bound. Also the output of mount | grep zram whill show entries in case zram is in use.
