ReadyNAS LCD error - frozen on boot - fans spinning
Hi all,
Came home today to find my ReadyNAS wasn't connected to the network. Went to the unit and the fans are spinning incredibly loudly, the sides of the unit are hot, and the LCD displays the following text:
"__switch_to+34"
Does not respond to the power button.
I powercycled with the cable, the device boots, starts doing a sync, and then freezes again on the same error message and fans start spinning again.
I did get emails from the device saying it was rebooting, and that it was syncing volume data.
Any ideas?

This doesn't sound good.
Is the NAS still under warranty (3 years for the original purchaser)?
I'd start by powering down the NAS, and testing the disks in a Windows PC with vendor tools (seatools or lifeguard). You can connect the them using SATA or with a USB adapter/dock. Label the disks by slot as you remove them.
If you can't do this easily, you might also check if one of the disks is really hot when you remove it.
Thanks StephenB.
I unforunately don't have access to any windows or linux devices. One of the disks was warmer on removal initially but would need to recheck which...
I did (after posting the message) remove all disks in sequence and reinsert and received a new error which looked like BTRF corruption. I managed to flash the original OS from the boot menu and reboot the device and slowly inserted the disks again - assuming one of them is the potential culprit
It's now been sitting on resynching data for the past 29 hours and counting. Up to 99.7x%... whether the RAID is recoverable not sure.
Wasn't aware the unit had a 3 year warranty but will keep in mind. I bought it a bit over 2 years ago.
Still unclear as to what the error is... or what will happen next.

Not sure exactly what steps you took here, but you might have lost your data.
Are you removing each disk with the the NAS powered down? Then power down after the boot test, restore that disk, and move on to the next?
