Thank you so much for your response! I was able to run the script and this is what I got:
I currently have no files on those disks. Is that the reason it failed? I am moving some files now from another location and should be able to test the script again afterwards. EDIT: I added the files and had the same result. Does the sync need to be run manually once before the script takes over?
Is it normal to not receive an email if the script fails? Also, is the email in the config script supposed to include the "" (e.g., "email@example.com") or entered without them?
Do you know if there is a guide out there somewhere about what to do with SnapRAID from the OMV5 GUI in case of a disk failure? I was thinking that since I am migrating data from another OMV installation running SnapRAID, that I could use that hardware to simulate a drive failure and see how the process would flow. This would help me be ready in case it ever happens in real life.
