Not Notified SMART Error. What I have to do?

Hi everyone!

Today I have updated my OMV server and do some controls in the OMV WebGUI and I notice that one disk of my RAID1 array is marked as RED in the SMART Panel.

I leave some screenshots and the output of smartctl-x for that drive.

My Storage work like this:

RAID1 -- Mirror Array real-time synced using Syncthing with my devices

BACKUP -- Backup Drive to do versioned-incremental backup of the RAID1 array via an rsync script.

The system didn't send me an e-mail with the SMART error so I don't know when this error happen. Could this be an issue? Are my DATA safe?

What I have to do? I have bought a new drive to replace the red one. This is enough?

I have already order a new drive. I plan to replace it on Tuesday. In the meantime do I have to worry or doing something else like removing the failed drive?

I have replaced the drive yesterday rebuilding the RAID1 array. The fact that the old drive had reallocated sectors could potentially have dameged data also in the other drive of the RAID1 array?

Thank's for the advice on HDSentinel for Linux! I will set it up soon for sure.

So I suppose it's everything ok because the "Relocated Sectors Count" S.M.A.R.T. attribute implicitly means "Successfully Relocated Sectors Count" or I'm wrong?Sorry for the question but I'm not an expert, I try to browse with google but I don't understand very well.
