Files randomly appearing in .Recycle.Bin / corrupting

[Talk2TheNight]

Hi all, 

I've been using UNraid for ~4 months now and have not had a single hiccup. Recently I noticed in a few of my shares I have random directories / files appearing as if they were manually deleted. They also are corrupt and missing a large chunk of the actual data (size vs size on disk discrepancy). I have the Recycle Bin plugin so I can see what has been moved in there. 

 

Can anyone help in recommending the next steps to figure out what is going on? Why are some random files being deleted? On of the files was a 30+gb archive that I now have to dig through backups to find a non damaged copy (fortunately I DO have backups for important data for this exact situation). 

 

Host:

Dell Poweredge R420

UNRaid running ontop of ESXi

Dell H310 mini - Flashed IT mode, hardware passed through to UNraid (I wonder if this crappy HBA is the problem)

4x 4tb HGST sata - all appear to be green / healthy according to SMART / Unraid

 

Notes:

Parity check 1st of every other month (roughly every 60 days). Last ran 51 days ago, running one shortly.

Primary use is SMB share and PLEX docker. No VM,

Disks spin down after 15 minutes of inactivity

 

 

Example of damaged files in recycle bin:

 

 

 

Thank you!

I notice others will put a log file, here is mine.

 

I was thinking that AV may be deleting the file but I see no logs of threat detection, suppose it is possible but I am not sure if that explains the size / size on disk discrepancy. 

 

Thank you!

Anything that winds up in the recycle bin is being deleted over the network via SMB, so the "source" of what's deleting the files is from another computer on your network.
