Greetings- I have unraid 7.1.4, Cache drive is Samsung_SSD_850_EVO_250GB. It is continually showing with ~119GB used, but largest actual file is a 28GB movie. Here are steps I took to find/troubleshoot (gleamed from scanning these forums and using GPT): Checked largest files with du — found only ~28GB visible (the movie) Verified no snapshots with btrfs subvolume list — returned nothing Checked for deleted-but-open files with lsof +L1 — found none after Docker restart Ran btrfs balance to defragment — minimal effect on used space Confirmed no hidden mounts inside /mnt/cache Noted deleted docker.img file was once open but no longer exists or held open Ran filesystem scrub — no errors found Performed deeper du scans inside cache — no large hidden files discovered Concluded space usage discrepancy likely due to BTRFS metadata/internal usage or hidden data not visible with standard tools Any suggestions or troubleshooting steps or videos you would suggest? Thanks community!
