Help, my ZFS is corrupt?

[Vanel]

Hi There,

I am running a filesystem with the following specs:

Hostname: freenas.local
Build: FreeNAS-8.3.0-RELEASE-x64 (r12701M)
Platform: Intel(R) Pentium(R) D CPU 3.00GHz
Memory: 999MB

I have two HD's in a software raid via ZFS. Currently the system crashes when I want to start the CIFS-service. A ZFS Scrup did not reveal any relevant information. It ended with 'No known data errors'.

In the log file I can find the following. What happent and what can I do to recover the data? Al help is appreciated!

Looks like you have a failing flash drive. Load up a new flash drive. Then go and boot it, and you can use the automatic import to bring your ZFS pool into the new FreeNAS's configuration.

More memory might help, too, but it can be an expensive deal with that processor. While 999 Mb is a bit low for ZFS, I just learned that the Pentium D does not support ECC memory. And I suppose it is using DDR2 RAM, so adding RAM would be expensive. Intel says the L2 cache is only 2 Mb and Physical Address Extensions on the processor are 32 bit but I'm not clear on what that means. It does give me the impression that the processor is probably old enough to be getting around on crutches. It might be a better performance option overall to replace the motherboard and the processor and feed ZFS a lot of memory.
