Help with expansion

Sorry, I keep making the same typo, Installed 4 pcs 2tb drives.

Finally pulled the plug last night, then waited.

Now every time I re-start I get expanding, file check, 4 hours later error Re-size 2fs

You must have an older unit that originally shipped with RAIDiator 3.x which had 4K block size while 4.1.x uses a 16K block to be able to address a larger array with larger disks. The only thing you can do is a factory default which will wipe all the data which is why I asked about the status of your backup. Never, ever trust all your data to a single device, be it a single drive or a single box.

However, if you will open an online case with technical support they may be able to telenet in and get you access to the unit. At that point, you should definitely create and maintain a backup. When you open your case, please edit your first post and add the case number to the end of the subject line.

OK, first of all I have two other NAS NV+ units. SO most of my data is ok.
This one did originally have ver 3 firmware. But currently is has 4.110 or so(updated a week ago). The last message I received after 6 hours was
Disk expansion error. resize 2fs

So when I restart, it will take 6 hours to FS check, then attempts expansion.

The drives are the NEW WD RED drives Model ED20EFRXSP

This should have worked?
I also updated the memory module last year.

This NV+ has the LCD in front.

You will need to factory default unless you have done so since raidiator 4.x.x.
Read this, there is some info on it.

OK, thanks I have performed the factory reset. I see the correct file size now.

But the nas has been doing a drive 4 sync for hours, like 6-8 hours with hardly any data on the drive.

When it finishes, I'll restart and pray....

You have a backup of all the data? Factory default wiped it all.

RAID like this needs to resync every block, even if its all zeros, it doesn't know about the filesystem layer.

OK, complete reset worked, but then did a 7 hours re-sync to the #4 drive.

Seems OK, should this -reset have taken so long?

It had to read every sector on the original three drives, compute the output sector and then write that to the fourth drive. The RAID is independent of the file system, so it is the same process even if the file system is empty. It is somewhat puzzling that it treated drive 4 differently from the rest.

You should check the SMART stats in frontview though, and make sure there are no reallocated sectors or other bad stuff before you load data back onto the NAS.
