ReadyNAS 104 kmem_cache_alloc+bc on boot error
Hello
I recently ran the firmware upgrade through the web portal on the NAS to 6.10.
Currently I am not sure what the exact previous firmware version was, but I update it fairly regularly when I see a new version so it couldn't have been much lower.
On first reboot after loading the new firmware, the device failed to fully boot up and showed error: kmem_cache_alloc+bc on the screen
I forced reset the machine again and got a new error of: kfree+168
Since that was a different error I for lack of any other knowledge on what to do, I rebooted it one more time.
However this time it went back to the original error of: kmem_cache_alloc+bc
At this point I do not know what I can do to try and get it booted up.
If anyone has any suggestions I would appreciate any help.
Thank you

I got it to finally boot when I removed the HDDs from the machine.
Once booted, I added the drives back into their same ports 1 at a time.
However, now I am not seeing any of my data or my shares.
Only thing that is still there are the user accounts.
Message I am getting is remove inactive volumes to use the disk.
How do I go about getting my data back. It should all be there as I have not created any new volumes or formatted them.
Thank you

That was a mistake, though I don't think it would do more damage.

The best way is to contact paid Netgear support (my.netgear.com).
Per-incident support might be enough to get the data volume mounted - I think the cost would be about $75 USD. JohnCM_S and Marc_V can help you sort out if per-incident support is the right avenue.
Of course if you have a backup, you can alternatively do a factory default and restore the files from the backup. After you recover your data (thinking positive!), I suggest that you put a backup plan in place for the NAS.
