I guarantee you they have not because this will have an impact on 100% of their units. So your assertion is that any disk replacement on any NV+ V2 will fail in this way? How many units have you tried this on??? Perhaps some other v2 owners who have tried replacing disks can comment. If the not-clearly-identified problem is really that ext4 doesn't work well when the disk volume gets full, I agree that is likely systemic. Though I don't think that would be a kernel issue, just a limitation of ext4. Anyway, I'd still delete the disk partitions on the new drive and re-insert it. I'd think you should also run vendor tools on it while it was in the PC. I would also invest in drives for backup - speaking from personal experience, a RAID array is not enough to protect against data loss.

It's not ext4 limitation, because can affect ext3 as well (when you touch journal with ext4 driver). if this is not a bug what it is?
This is problem with driver or journaling in it - not file format!

But if anyone have free time - he can try to disable journaling in ext4 (because I think that this can solve problems).
