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...
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.
Thank you - I will try that now.
Unfortunately rebooting with drive 2 removed, and skipping the volume check hasn't worked. It never gets past:
Booting . . .
Resyncing volume.
The LED for disk 2 is flashing, and the blue power light is flashing.
I'm not sure what I should try next. Should I try putting a replacement disk into slot 2?

It looks like it is still trying to access disk 2.
Maybe power down, and remove the mains power for a few minutes. Then try booting up again (still skipping the volume check).
No change I'm afraid - the behaviour is just the same.
- 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.

Thanks to you both - I need to go out just now, but I will try that later today.
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
In a terminal window:
(1) sudo su
(2) apt-get install fuseext2
(3) apt-get install lvm2
(4) modprobe fuse
(5) vgscan
(6) vgchange -ay c
(7) fuseext2 -o ro -o sync_read /dev/c/c /mntNot 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).
I've tried with the new disk replacing disk 2, and using the boot menu to skip the volume check. I'm afraid it still doesn't get past
Booting . . .
Resyncing volume.
Have I now exhausted all possibilities, or is there anything else worth trying?

Well, it does need to resync the volume. How long are you waiting for that to complete?
Have you tried accessing Frontview (or seeing if the shares are accessible)?
I left it resyncing for about 2 days.
Sadly I can't access it through Frontview, or view the shares.

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.
