Readynad duo v2 root danneggiata e disk failure
Buon giorno a tutti , posseggo questo nas da parecchio tempo , circa 2 settimane fà ha smesso di funzionare , emetteva un suono ciclico costante metallico , tipico degli hard disk tralaltro , uno dei...
I mark this discussion as resolved because while waiting for the SATA/USB adapter I tried to install the new disks and the NAS does nothing, it is not possible to access the web interface, I tried to perform the reset, but nothing has changed, so the NAS is dead and I just have to recover the data as you described with Linux, so this discussion is to be considered closed, or resolved, I thank everyone for the time you have dedicated to me, I thank you and I wish you many beautiful things, not only in this world where however you are very good and competent, thanks again for everything, "Ciao", Marco from Padua, Italy.
First, you need to determine if you REALLY have a "V2". Netgear used the "v2" designation for some minor changes and later came out with a product also called a "V2" that's an entirely new NAS but looks similar. If the unit says "V2" on the front and RAIDar identifies it as a "V2". then it is one. Otherwise, it's the original, or V1. This is important because the V1 cannot accept drives larger than 2TB.
If you cannot successfully boot the unit with just the "good" drive, then replacing the other will not help at this point. "Corrupt root" may be because that drive also has a failure, or just may mean the OS was damaged when the other failed. An OS re-install will likely fix it if it's the latter. How you do that depends on whether it's a true V2 or a V1. But before trying that, it's best if you test the "good" drive using a PC and the drive vendor's tools to see that it does not also have a failure. If it does also have a hardware issue, there are methods that may recover your data, so come back for help with that. But for now, let's assume the drive is physically OK.
"Corrupt Root" on a new drive likely means it's already formatted. Doing a factory default with just that drive installed should allow it to go forward. That's a good step to insure the NAS hardware is OK. But be sure to use only the new drive, as a factory default erases all data. When you get to the point that the NAS boots with just the one older drive, then you can add the second with the power on. Then, you'll need to format the drive on the NAS to remove the data put on during the test with just it and the NAS will then add it to the RAID.
As for your replacement Red Plus drive, that's a good choice for your NAS if it's a "real" V2 and can accept a 4TB drive. It uses CMR recording. If yours is actually a V1, make sure you get another Red Plus or Pro or a Seagate Ironwolf 2TB. AFAIK, every desktop drive in that size range will be SMR, as is the WD Red (not RED Plus), so should be avoided.
