New Seagate NAS Drives

Let us know how they work out!

So I previously had 2 1397GB ST31500341AS drives on my NVX (running RAIDiator 4.2.23).

I added this 1863GB ST2000VN000 drive and although it restriped fine with no issues (took only 10hours), my NVX did not appear to use up all the space on the new drive, even after a reboot. It only expanded it to the size of the smaller drives (1397GB).

I thought the benefit of XRaid-2 was that it would expand up to the size of the new drive you put it. Doesn't seem like it did that.

You need a second 2TB drive in the NAS before the full 2TB can be used. X-RAID2 volumes provide redundancy. If any one disk fails data remains intact. Adding one 2TB disk only 1.5TB of that disk (in your case) could be made redundant.

Aha, I had a feeling that was the case.

I was hoping I could just keep the additional drive as an extra for whenever of of my two original drives went 'kaput'. One of my drives SMART 'Reallocated Sector Count' has been slowly creeping up (now at 65) so I might have to be prepared to replace it when it dies.

Anyway, the good thing is that this new Segate NAS drive seems to be working well. Zero SMART disk errors on day one. I'll keep it in there for a while before deciding to add the second one in.

It probably is better to replace the failing disk than to leave it in till it dies.

I agree. You have the replacement on hand, I'd use it now. Otherwise you are risking a double failure, which could cost you your data.

BTW, if the failing drive is still under warranty, you might want to run seatools full-write test on it after replacement. Reallocated sectors only happen on failed writes - often the count will rise substantially if you attempt to write to every sector. If you purchased the drives near your forum join date, you will need to move quickly (assuming a 3-year warranty).
