empty share after autodefrag
I'm operating several RN312 und one RN204 with 4x2TB in Raid 5. On this one free space was abt 900 GB. One share share with abt 100 recorded TV-mp4-videos showed a figure of 16777216.0 TB to be used. Then I activated auto-defrag on this share, got no message and nothing in the protocols . When I checked, free space is 1.8 TB and counter on the share is still the same 16777216.0 TB. The share contains no more files exempt file thumbs.db with 37 kB. No snapshots on this share and no backup. Can files be recovered?
