Unable to enter boot menu on ReadyNAS 312
Hi,
After a power failure my ReadyNAS 312 system fails to boot, it simply hangs with fans being quite noisy. I tried to enter the boot menu by pressing the reset button at the back during power-on. I used this procedure a couple of times in 2013 when I purchased the unit, so I am familiar with it. Hooking up a monitor I can see the BIOS welcome message, and then Loading kernel, Loading initrd.gz ... ready, after which nothing else happens. The LEDs that should come up at the front don't. The only LED lit at this point is the one labelled 'Act'. I should note that the unit runs a modified kernel (I added iptable support in order to use it also as a firewall between my local network and the outside world) and it has saved me well for over a year with this modification.
Any advice? Any chance I can boot from a live linux system on a USB-stick in order to troubleshoot the system?

- Looks like disk sda has been marked as failed. Perhaps that disk has failed.
What kernel version are you running?
What version of btrfs-tools do you have?
The versions you have might not be new enough to be safe to use. - kernel version is 3.13.0-39
btrfs-tools version is 3.12-1 Looks like disk sda has been marked as failed. Perhaps that disk has failed.
Can I try to boot the system with disk 1 (sda) removed?- Yes, though you might want to power down the NAS before you remove it.
- I'd feel more comfortable using a newer kernel and a newer version of btrfs. We use btrfs-tools 3.17.x currently.
- I am right now running a low level diagnostic tool on the Toshiba disk that failed. If that will find unrecoverable problems, would I be able to replace the disk with another make (I have Seagate and Western Digital in stock) or is the ReadyNAS 312 picky about the brand of the disks?
- You can mix/match disk models and vendors. Based on many forum posts here, I'd be careful on the Seagate DM series and WDC green drives. I use NAS-purposed drives myself.
- Ok, I now have hot-plugged a new 2 Tb disk and the system is busy with RAID recovery, which I can follow via /proc/mdstat. By tomorrow morning I should have a fully restored system, without losing a single file. Thanks everybody!
