I upgraded Influxdb from 1.3.6 to 1.4.2 and it seems to work fine for all databases except for one, where after the upgrade show tag keys does not return any values. I run all dbs with tsi1 index and I did the conversation as mentioned in the changelog.
There is no error in the logs, all tsm files are healthy and the system performs well.
I am a bit puzzled and not quite sure what to do as for this particular db, non of the measurements gets new tags, but data is written to it and new series are created, just no tags.
Is there a way to reload tags?
