Upgrade influx 1.8.10 to 2.6 -Empty retention policy, no shards found-

Hello :slight_smile:

My OS is rasp. Bullseye 64 bit
I tried to upgrade influxdb 1.8.10 to 2.6 without success My v1 database has not been tranfered to 2.6.

Here is a log excerpt {"level":"info","ts":1672221160.0119205,"caller":"upgrade/database.go:223","msg":"Computed disk space","free":"241 GB","required":"412 MB"} {"level":"info","ts":1672221163.3943026,"caller":"upgrade/database.go:51","msg":"Upgrading databases"} {"level":"info","ts":1672221163.4196975,"caller":"upgrade/database.go:101","msg":"Creating mapping","database":"iobroker","retention policy":"autogen","orgID":"eade2635eee38ce5","bucketID":"535f3b59ef564778"} {"level":"warn","ts":1672221163.4262733,"caller":"upgrade/database.go:158","msg":"Empty retention policy, no shards found","source":"/var/lib/influxdb/data/iobroker/autogen"} {"level":"info","ts":1672221163.4425917,"caller":"upgrade/database.go:101","msg":"Creating mapping","database":"iobroker","retention policy":"global","orgID":"eade2635eee38ce5","bucketID":"6f63b2de2760211b"} {"level":"info","ts":1672221180.7800333,"caller":"upgrade/database.go:195","msg":"Database upgrade complete","upgraded_count":1} {"level":"info","ts":1672221180.7802277,"caller":"upgrade/security.go:45","msg":"Upgrading 1.x users"} {"level":"info","ts":1672221180.7944946,"caller":"upgrade/security.go:115","msg":"User upgrade complete","upgraded_count":1} {"level":"warn","ts":1672221180.7946594,"caller":"upgrade/upgrade.go:483","msg":"1.x users were upgraded, but 1.x auth was not enabled.

The problem seems to be ‘Empty retention policy, no shards found’.

What went wrong here? Maybe someone can help.
