Data retention period is not as expected

[cao2358]

I reduced the data retention period. After restarting the service, I found that the old data was not removed. Regarding the disk usage problem, is there any way to solve it through horizontal expansion?

Hello @cao2358. I'd like to clarify if the old data is shown in the UI or you just see old files on the disk. May I ask you to post the configuration please? Also, if it is possible, could you please post here what the pyroscope_storage_retention_task_duration_seconds metric shows (it is available via /metrics HTTP endpoint)
