Recovery after power supply failure
Hello forum --- I had a ReadyNAS RND4000 which experienced "the power supply problem". It had two 2TB drives, so 2TB of dual-redundant storage total. Netgear tech support promptly got me a new chas...
Thanks for the reply!
The hardware versions are both v3, though that was a great thing to recommend checking.
"powering down the NAS, inserting the original drive 1 in slot 1 (by itself, no other drives!). Then start up the NAS - and when it boots, then hot-add the new drive to slot 2." --- this is what I tried to do, per the second paragraph in my post; it does not boot with the data drive; it says "ERR: Bad firmwar". At no point did I hot-remove or hot-insert any drives. There was always a power-down between drive changes --- apologies if that was unclear.
Thank you for your good advice regarding backups, but my issue right now is that I have two drives which each independently have all my data. I have, if you will, two backups already in my hands. The issue is that the ReadyNAS will not read them. The "clumsy and time-consuming approach" I referred to above would be to buy a SATA adapter for my Linux laptop, mount one of the data-full drives, set up a network link to the NAS with a fresh drive, and transfer all the files. This seems like defeating the purpose of having a NAS system with swappable drives; since the instructions for getting new hardware per Netgear are "just plug it in" (http://www.readynas.com/kb/faq/boot/how_do_i_migrate_disks_over_from_an_existing_readynas_to_another), which is what I would have expected, I felt that I must be missing something.
So I suppose my question can be rephrased as: why, when I follow the instructions in the above how_do_i_migrate link, do I get a "firmware error"? I'm migrating one of the drives, not both; but a failed boot seems like a harsh error for a system that is designed to elegantly deal with having one of its drives disappear.
Thank you again for your thoughts on this, I truly appreciate your time and expertise.
