I'm running influxdb from a remote file system (CIFS) on a raspberry.
After start it works pretty good for few hours and then when I try to list the series (using show series;) I get following error:
ERR: SHOW SERIES [panic:runtime error: index out of range]
After restarting application everything works fine again for few hours. I tried adding more logging but there are no errors there or useful info entries.
I'm quite puzzled why this happens, googling returns mostly error for golang.
EDIT: Actually I found some logs for this:
lvl=error msg="SHOW SERIES [panic:runtime error: index out of range] goroutine 10617 [running]:\nruntime/debug.Stack(0x31e91d0, 0x30ecf00, 0x

but they don't help much :(
CIFS is a problem. Probably InfluxDB files are corrupted - see https://github.com/influxdata/influxdb/issues/10309
InfluxDB isn't supported on network file systems (e.g. NFS, GlusterFS).
