ReadyNasUltra 4 dead #26795494
One of the disk was showing increasing Smart errors, so I ordered a replacement disk (ST3000VN000) -to replace the failing disk. No big deal I thought.
I had assumed that the failing disk was d...
Netgear support managed to rebuild the array remotely, using mdadm and then mount the array.
Powered off, removed the bad disk 1 and rebooted with only disk 2,3 and 4 and then could access with fontview.
Put the new disk in disk1 slot, and the raid array has re-synched and we're now back online, all data intact (AFAIK).
Now looking at implementing crashplan on the Ultra4 - though not sure how long it would take to upload data!
I looked at the status log to see the warnings that were given and looked at mdstat.log to see a quick overview of the current state of the array.

Of course it depends on your uplink and the congestion on the path to their servers. My backup speeds vary quite a bit - usually between 16-75 mbits. Du-duplication helps by reducing the data transfer - especially on my image backups.
If I were doing it over today, I'd install crashplan on a PC and mount the NAS as a network drive letter.
One reason is that over the past year they have upgraded their platform requirements a few times, and I am guessing that will continue. There were some bumps in the road over the summer (where new Java and a new glibc were needed on the NAS).
Another reason is that crashplan deduplication can use a lot of memory. If crashplan doesn't have enough memory, it basically stops working. I believe an ultra-4 has only one memory slot, and is limited to 2 GB ram max. My pro-6 can (and does) use 8 GB, but the java vm is limited to about 3.7 GB.
FWIW, there is a way to turn off de-duplication if you hand-edit the config file. But Crashplan really doesn't want you to do that (one reason is that it increases their cloud storage costs), so my guess is that they will close that option off.
