ReadyNAS NV+ stall during File System check at 19%
My ReadyNAS NV+ is stalling during the File System check at 19%. It is visible in RAIDar, and all four disks register as healthy, until the 19% point is reached, at which point RAIDar cannot find t...
Hi Stephen,
I've left a backup disk plugged in to hopefully run a scheduled backup overnight. I'm not too optimistic, because for some reason, after being connected for a time the NAS seems to become unreachable.
I've installed FireFox version 94.0.2 ready to try with Frontview tomorrow or at the weekend. I've no experience of SSH, but I have a brother who works in IT support, so I'm hoping he can help (unfortunately he is on holiday until the week after next).
Cheers,

Hi,
I have not been able to spend time on this in the last few weeks, but I'm able to pick it up again now. The latest position is that it now does not get past the disk 2 sync on bootup. I was unable to run a backup, so unless there is something else worth trying, I am thinking that the only option left is to try replacing disc 2 and see if it rebuilds. If that is the best way to proceed, should I do the swap with the NAS powered off?
I was briefly able to access Frontview, and I can't remember the exact wording, but it indicated that disk 3 was beginning to exhibit errors so should be replaced soon. So I am assuming that the best case scenario is that I have to replace two disks, but there is also a risk that disk 3 has now failed, and all I can do then is a clean build.
Cheers

It is best to do the drive swap with power on. If a second drive is bad, or goes bad during the re-sync, then you will have to do a complete re-build. And an already failing drive is very much at risk of total failure during the heavy load of a re-sync.
So, make sure that backup really is up to date. You may also want to just bite the bullet and replace both drives and re-build, which will require only one sync, not two and is going to have a lower possibility of drive failure.
Thank you for the advice. Unfortunately, my backup isn't up to date, due to human error. However, with some effort, I can rebuild it. All the document type files are also saved in the cloud, as are any new photographs. The main inconvenience will be a fairly large quantity of music CDs which will need to be ripped again.
Given that the worst case scenario is a full rebuild, I think I will take the risk of a disk failing, and start off with replacing disk 2, which at the moment is failing to sync. If by a stroke of luck that works, then I will try replacing disk 3 next, as there was a report of that being in bad shape. If I have to resort to a full rebuild, both of those will need replaced anyway. Looking on the bright side, it will be an opportunity to start upgrading the disks from 1GB to 2 GB.
I will report back on progress.

I suggest starting by
- power down the NAS, and removing disk 2
- reboot the NAS using the boot menu option to skip the volume check.
If the system boots correctly, then update your backup.
