Hello Unraid Community,
I'm facing a concerning issue on Unraid server and am desperately in need of assistance. I was managing data, intending to clear some files and transfer data between disks using Krusader (docker). Accidentally, I pressed the delete button on a vital folder containing approximately 1.5 TB of data. I realized the mistake almost instantly and pressed cancel within 3-4 seconds. Nonetheless, the folder vanished, and the data now appears as missing on my main disk.

Given the brief time span between deletion and cancellation, I suspect it might be a case of file or folder link corruption rather than a complete data deletion. The disappearance of this data is quite distressing, and I am at a loss on how to proceed. I greatly value any insight or suggestions from this knowledgeable community on how to identify and rectify this issue. Your help in this challenging situation would mean a lot to me.
 

Thank you very much in advance for your time, consideration, and support.

Make sure nothing else is written to the array, if you are using xfs you can try this, another option (or for different filesystems) would be to use a file recovery util like UFS explorer.
