Volume: The volume XXXX encountered an error and was made read-only. It is recommended to backup
Hello, I have just received this notification: Volume: The volume Volume1TB encountered an error and was made read-only. It is recommended to backup your data I just checked and the volume is mark...
Well, end of the story. For posterity:
when it happens, do not attempt anything except a backup copy.
Files should be ok (they were all fine in my case, no data loss), as someone else said in another similar thread office files won't open, but I think it's because office tries to lock them and it is not able to write on the share, but if you copy them somewhere else they will be ok.
But don't do anything else, after I tried to reboot the volume was completely gone, together with the data.
If this failure happens in the volume including the first disk, applications are lost too. Lesson learned here (it took a while): backup all configurations in a share, which is backed up again.
My two 6-months new WD HDD are now moved to external USB units for automatic backup and two new Seagate Ironwolf disks are in.
Rebuilding is in progress (my personal discovery, copy files from backup USB unit to volumes is a lot faster if done from SSH), let's hope it will last for a while...
Thanks again to StephenB for the support!

Two questions: the volume with the problems include the first and the second disk of the NAS. If I remove those, am I going to lose also the OS and do I have ot restart from scratch? Is the second volume also going to be affected?
The OS partition is present on all your disks, and is mirrored (so it should be up do date on all disks, and the NAS should boot w/o the first two).

All applications have disappeared now: is there any way to re-enable them so I can try to save the settings and avoid the complete reconfigurations of all services?
Apps on the other hand are actually installed on one of the data volumes (generally the first one). So are the home folders (if you use them). Unfortunately Netgear doesn't provide a way to back up the apps. But it is possible to copy them to a folder on the other volume.
Ok, understood.
Well I'm glad I didn't even try something so harmless like a reboot before making a second backup. Now the volume is completely gone and marked as inactive. All applications are lost (sigh, again reconfiguring everything...).
Well, I admit it's rather scary that something that is not even a hardware failure causes the loss of the entire RAID1 volume. One broken drive caused less harm than whatever happened here.
