Since noone answered my Github issue so far recovered from panic opening boltdb file: invalid freelist page: 0, page type is unknown<00>\nerror creating index client · Issue #7694 · grafana/loki · GitHub. I’ve decided to ask for help here and apparenty I’m not the only one having this issue. Loki stops working after a few hours with the following errors
