Hi @yasharne
It looks like your configuration still refers to -boltdb.shipper, which was deprecated in favor of -compactor:

loki/docs/sources/release-notes/v2-9.md

Line 33 in 2de6e16

- The `-boltdb.shipper.compactor.*` CLI flags are deprecated in favor of `-compactor.*`.

The BoltDB store is deprecated in Loki 3.0. You should migrate from BoltDB to TSDB, and then perform the Loki upgrade. This is mentioned in the TIP in the Loki upgrade documentation
