ReadyNAS Ultra 6 - ERR: Could not properly extract
I am attempting to resolve a problem with a friends Ultra 6 that has me at my wit's end. In short, an attempt had been made to upgrade this legacy unit to OS6 and during the process, the update fail...
The NAS was not caught in an OS update.
After numerous efforts way too involved to mention here (I barely understood what I was doing since I'm not a Linux guy), it turned out that the problem was one of the simplest possible. Turned out that the 1GB factory memory stick was defective. When I attempted to run a Memory Test from the Boot Menu, the test progressed for 8 seconds and then stalled.
Swapped memory between the problem machine and a good Ultra 6 and the memory test on the bad machine ran to 100% while the good machine stalled at 8 seconds. With the unit now running with good memory, all previous failed efforts (manual OS upload and factory reset) progressed through completion without encountering the "could not properly extract" error.
I have to say I'm very surprised the system would boot and run with faulty memory, which is why I didn't consider a memory test early on in this process. Needless to say, a memory test will be the first thing in my arsenal if any problems are encountered on a machine from this point forward.
Thanks to those who contributed to the thread and via PM. I definitely learned a lot while debugging this system.
Is the NAS in the middle of trying to do an OS update? Maybe it's the update it can't extract from. I don't know how to stop it from continuing to try the update if that's it, though. I'm at the limit of my knowledge of the ReadyNAS boot process, so I hope whoever PMed you can point you in the right driection.
