Mimir store-gateway pvc cleanup

Hi All,

I recently received an alert indicating a reduction in available space on the PVC for the store-gateway. Upon further investigation, I noticed that there are old directories in the /data/tsdb-sync/anonymous directory dated back to August, September, and October.

I would like to seek your advice: Is it safe to delete these old directories to free up space?

Thanks in advance.
