@NoSuck, the problem with ECC is that you would want it everywhere your data happens to be at some point of time or another: including all buses that it traverses. I have yet to see such implementations even on servers (not saying they don't exist, just that I've never encountered such in my practice), and it's certainly not something that you could find on any desktop. In other words, ECC memory saves you from yet one more place where your data can go corrupt -- and a very important and vulnerable place, indeed -- but that's it. To say that without ECC memory ZFS is pointless, and vice versa, that with ECC memory and ZFS a system is bulletproof against bit-flips and other data corruption is, mildly speaking, unprofessional.

@NoSuck, I do -- and have used it for more than 5 years now on my desktop (first two years on FreeBSD, two years on Ubuntu, and the last year on Arch). It's certainly better to use ECC memory, but it's not a strict requirement either.

@senorsmile Thanks. A lot of the documentation seems to stress the importance of ECC to the point of making ZFS seem pointless without it--though I suppose now that such documentation is aimed at large-scale server admins. (Original post, deleted because demizer mentioned using non-ECC RAM in a previous comment.) @demizer Do you (or anyone else) use ZFS with non-ECC RAM? I'd love to use ECC RAM, but my current mobo doesn't support it.

Not a requirement, but recommended. I use zfs without ecc ram.

I have over a dozen machines running zfs withOUT ecc ram. For desktops/laptops, it's pretty much the norm. ECC ram helps you, especially with scrubs, but it's certainly not a requirement. Your data is still safer with zfs and nonecc ram than without zfs and nonecc ram.

@butler360 Did not know that existed! Thanks for the tip!

You don't use mcelog demizer?

@Fardbdose, AFAIK the ZFS packages work best on x86_64 with lots of ECC ram. ZFS is ram intensive, especially when performing scrubs. Last year I had a scrub go bad when one of my ram modules died and I didn't recognize the symptoms (chromium tabs crashing for no reason). The bad memory caused the scrub to produce incorrect checksums which in turn caused the scrubbing process to attempt to recover the file, which failed. At the same time, one of my drives failed leaving me with a very degraded system. Amazingly, I was able to get back to a fully operational pool after replacing the drive and memory. After doing a second scrub process, only one file was unrecoverable, of which I restored from backups.

@Farbdose the banana pi does not ship with 3.18.1-1 but an 3.4.90 kernel, this should not be a problem. But I would not recommend to try this on a banana pi because of the lack of RAM.
