I have InfluxDB 1.8.1 installed on a Raspberry Pi writing TSM files to a NAS drive.
The Pi got a corrupted SD card last week and I have had to rebuild it on a new card (it was backed up but I cannot access the back up now - long unhappy story).
While everything is working again it seems that Influx has started writing to a new shard and does not know that the old data is still there. The WAL directory was on the Pi SD card so it has gone but the TSM files are on the NAS drive and are still there with 9 months of data.
Is there a way to rebuild the database from the TSM files?
TIA for any help or advice.
