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 the NAS.
From other posts it sounds like one possible cause is overflowing log files. Is there any way to clear these, or verify if this is the issue? I can't get into 'setup' as the file check doesn't reach completion.
Due to human error, my backup is several months out of date. The missing information is music from CDs, so I could recreate it, but it would be very time consuming. Ideally I would like to resolve the NAS issues and get it back up and running.
Re: ReadyNAS NV+ stall during File System check at 19%
Hi Stephen,
Thanks for the quick response. It is an NV+. I hadn't tried skipping the check with the boot menu. In fact I didn't know you could do that. That was a definite step forward. RAIDar now runs fully, and my PC sees the NAS and I can access the files. I can see that the firmware version is 4.1.16. I am not sure what I should do next to restore the NAS to its previous condition. My instinct is to connect one of the backup disks to see if the scheduled backup runs. The NAS has four 1TB disks. However, presumably one or more of the NAS disks has some kind of issue which needs to be resolved. I don't know if it is relevant, but during the boot process a message came up on the screen saying that 'Disk 2 was syncing'. None of the other disks were mentioned.
A secondary issue I have is that when I click on the Setup button I get a security message from the browser that it does not support TLS 1.2 protocol. I have tried with several browsers, but none allow Setup to load, so I am not sure how to get round that.

Great. BTW, 4.1.16 is the most recent (and final) firmware for your NAS.

It is relevant - resyncing means the disk contents were reconstructed (using RAID parity) from the other disks. This will happen when you replace a disk, but there are also situations where the array gets out of sync. In this case, some writes to disk 2 probably never completed - perhaps due to a system crash or power loss. Whatever the cause, the system detected it, and automatically rebuilt it.
There could still be some file system issues (caused by whatever triggered the resync), so there could still be some lost or corrupted files. If the resync has completed, you could try restarting the NAS normally and see if that completes. But I do suggest getting an up-to-date backup first.

To clarify, the issue is that the NAS doesn't support TLS 1.2 - most browsers deprecated TLS 1.0 a few months back.
Another option (useful for either Macs or Windows PCs) is to download an older version of FireFox (version 94.0.2 will work). Make sure you don't let the browser update during the install, and right after the install completes, disable auto-update. If you are comfortable with ssh, there is a configuration file in the NAS that you can change to let you reach frontview with ordinary (unencrypted) HTTP. Or you can make sure you keep the older browser around, and only use it to access the NAS.

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).
Re: ReadyNAS NV+ stall during File System check at 19%
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.
Re: ReadyNAS NV+ stall during File System check at 19%
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.
Re: ReadyNAS NV+ stall during File System check at 19%
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.
Re: ReadyNAS NV+ stall during File System check at 19%
If you already have a replacement disk for #2, I would try again and this time put in the new disk. It should pass all the bootup tests, but if not, reboot and skip them. Then once booted, you should see #2 resyncing again. Now, another option because the readynas series is just using linux is to turn off the unit and move all the drives to a standard pc and then boot up a linux live cd. If everything auto configures, you should be able to see the entire volume and update your back up manually. Then you can put the drives back in the readynas, boot back up and continue trying to get it to work or just redo it.

On the intel ss4200-e, a lot of linux flavors would just recognize the volume when someone moved the drives to a computer. Not sure exactly what netgear's setup is like though as I've seen some of the threads on trying to do this and it's a bit more complicated for sure. Someone just needs to make a 'readynas recovery build' version of linux that will have all the tools to do it out of the box. Wouldn't even have to be recent as most of us having to do recovery are working with the older os4.
For sparc-based 4.1.x systems, the process I've seen posted is
Simple step by step guide to mounting Sparc-based ReadyNAS Drives in x86-based Linux: Tested on brand new install of Ubuntu 10.10 (32bit x86), no other dependencies- 23rd Jan 2011
Not something I've needed to try myself. It is quite likely that this will not work with a degraded array (as this one clearly is), as the normal RAID mode used by the 4.1.x systems uses hardware acceleration (and the data volume area on the parity disk is not partitioned).
Re: ReadyNAS NV+ stall during File System check at 19%
What brand and model drive did you use? If it's an SMR drive (most smaller desktop and WD Red drives). it will take a long time, though 2 days still seems a lot.
Re: ReadyNAS NV+ stall during File System check at 19%
It really depends on what your goal is at this point. If you have a backup of the data and simply want to restore the nas, I would 'nuke it from orbit' and start again, just reset it it with one wiped drive and rebuild from there.
Re: ReadyNAS NV+ stall during File System check at 19%
The message has moved on to 'resyncing disk 2', but has been stuck at that for several days. I've decided to move on and replace the disks. My brother might have a go at the Linux recovery route, but at the moment, I'm going to start afresh with new disks to create a blank system, and install the out of date backup, and then re-build. My question now is, is there a procedure for adding the new blank disks that will preserve the existing NAS settings?
