ok .... I will opt for the replacement. thank you
I doubt this message will go away by formatting. It tells something about the usage conditions of the drive in the past.
You eigther believe the disk is ok and live with the message or you replace it. What you do is a matter of backup concept and faith.
I still have a question. In your opinion, the second disk, the one "of the values wrong in the past" I could try to "remove" it from the RAID, format it and try to rebuild it, or is it much better to replace it? Thanks to those who will have the desire and time to answer me.
thanks for the instructions. everything was fine I replaced and the HD was recreated in about three hours. thanks for all your help.
Apologies, yes you're correct, Remove not Delete, I stopped using Raid some time ago
Don't worry, no problem. Thank you very much
I have read the procedure but maybe instead of delete I have to use remove? The delete key cannot be activated. I attach screenshot
If you read what I posted above when you click delete a dialog will display with the drives in the array
Okay thanks. I'll try
Alles anzeigenIf you're going to replace them, all this can be done in the GUI, once you've identified the two drives;
Raid Management -> select the array, on the menu click delete, from the dialog select one of the drives you want to replace, click OK, the drive will be failed and removed from the array.
Shutdown the server, remove the drive you have just failed and install new drive
Restart the server
Storage -> Disks, select the newly installed drive and click wipe on the menu, select short and wait until completed.
Raid Management -> select the array, on the menu click Recover a dialog should display with the newly installed drive, select it and click OK, the drive will be added to the array and it will commence a rebuild
WAIT until rebuild is complete to replace second drive, DO NOT REBOOT
ah here, maybe it is for this reason that I tried to enter recovery and it did not give me the possibility to replace any disk. Do I have to delete it first? So I go into RAID management and do I have to delete? I was afraid to erase the whole RAID ... 
As the arry still thinks the drives are ok, you have to mark them failed before you can remove them.
Do the repalcement one disk at a time and give the array enough time to rebuild. I wolud start with the one which has errors, not with the one which has been used outside its working conditions, as I presume the faulty one is earlier to fail, but that is just a guess.
I had tried with RAID recovery management but I was not able because it did not give me the possibility to replace any of them. He will try. Thank you
I tried to replace them, but maybe I got the procedure wrong. Can you advise me how to do it?
In the evening I will try a smart test again and post the result. Thank you
Hi everyone. I built my system using 6 drives 1 TB mounted in RAID 5. Scanning the drives I find two red dots. Going to see the detail gives me the following information. On one it says to me "Device has a few bad sectors" and on the other "Device was used outside of design parameters in the past". I ask you, what should I do? Do I have to worry? I tried to do the Recovery procedure on the RAID but it doesn't give me the opportunity to do anything.
I've already tried searching the net, but haven't been too good or smart in finding a solution to my problem. If I can I attach some images.
Currently my OMV version is 5.5.16-1 (Usul)
I am attaching the details of my RAID:

Queste cose non accadono da sole: hai spostato i dischi o i collegamenti? Non è assolutamente normale un comportamento del genere, soprattutto se perdi le configurazioni.
E ovviamente questo non viene causato dallo spostamento del server in rete.
Hai smanettato con il file system?
Purtroppo non credo di aver smanettato con i dischi ma succedono cose strane. Per esempio gli indirizzi fisici dei dischi, quelli che finisco per /dev/sda /dev/sdb /dev/sdc ... è normale che cambino a seconda dell'accensione? In questo caso, quello che nella foto indica come sdf è l'SSD dov'è installato il sistema operativo... ho riavviato tutto e l'ordine è cambiato. Cosa devo fare secondo te? Reinstallare tutto può servire? Non ho ancora finito di trasferire i dati...

Hello everyone, I'm new to the forum. I apologize in advance if anyone has already had the same problem as me. I have been using OMV5 for a very short time and I am very happy with it, I used an old Dell Optiplex740 pc with 6 hd 1 Tb in RAID5 and s.o. installed on 128gb SSD. I assembled it and made several tests without any problem.
Then I decided to start using it "seriously" I moved it to the network where I have to use it, manually changing the static IP address and gateway.
The nas still works, I see it on the net both from windows pc and mac. However, when I try to enter the folders, after a while the message "the drive is no longer available" appears ... I checked all the parameters and I realized that in the shared folders there are the access permissions have changed device connections.
There is no more RAID, but the address /dev/disk/by-id/md-name-SERVER.local:Raid6HD appears
If I go to modify it manually (as seen in the photo) I can normally access the folder and I can save, delete and / or modify all the files, until the next start. Yes, because when I turn off the machine and restart it I find these settings with these links. Has this ever happened to any of you and how can I fix it? Thank you
Buongiorno a tutti, anche io italiano.
Utilizzo da pochissimo OMV5 e mi trovo molto bene, ho utilizzato un vecchio pc Dell Optiplex740 con 6 hd da 1 Tb in RAID5 e s.o. installato su SSD da 128gb. L'ho assemblato ed ho fatto diverse prove senza nessun problema.
Poi ho deciso di iniziare ad utilizzarlo "seriamente" l'ho spostato nella rete dove devo utlizzarlo, modificando manualmente l'indirizzo IP statico ed il gateway.
Il nas funziona ancora, lo vedo in rete sia da pc windows che mac. Quando però provo ad entrare nelle cartelle, dopo un po' compare il messaggio "l'unità non è più disponibile" ... Ho controllato tutti i parametri e mi sono accorto che nelle cartelle condivise sono ci sono i permessi d'accesso sono cambiati i collegamenti dei dispositivi.
Non c'è più RAID, ma compare l'indirizzo /dev/disk/by-id/md-name-SERVER.local:Raid6HD
Se vado a modificarlo manualmente (come si vede in foto) riesco ad accedere normalmente alla cartella e posso salvare, cancellare e/o modificare tutti i file, fino al successivo avvio. Già perchè quando spengo la macchina e la riavvio ritrovo queste impostazioni con questi collegamenti. E' mai successo a qualcuno di voi e come posso risolverlo? Grazie
