What to do after drive loss?

[Fox01]

So I had all settings as default with drivepool and today one of my drives died. 

Now since all my data wasn't stored on that one drive...what would be my best course of action to determine what data I have lost? 

It was a 228TB and the drive was a 3TB drive.

 

Thanks.

As DrivePool relies on the file system as to which drives contain which files, if you didn't have duplication enabled then you'd have to compare with a recent backup or saved listing you've made if any to see what files are missing.
