I have 32gb non-ecc ram. I also use raidz-2 with six 3tb disks on http://amzn.com/B002RL8I7M with weekly scrubs. Smartd also sends me email if errors are detected on my disks. So far I have had three drives fail since 2012. ZFS has been a joy.
This weekend I am going to setup http://www.mcelog.org/ for additional protection.

Check out episode 31 of BSDNow for a discussion - they had an interview with one of the OpenZFS devs in another episode. Also, read this blog: http://blog.brianmoses.net/2014/03/why-i-chose-non-ecc-ram-for-my-freenas.html . My current pool (a 2 disk mirrored VDEV with weekly scrubs) has been on Ubuntu, Arch, FreeBSD, and back to Arch, through 3 HDD replacements, all with the only issue being NFS syntax differences between Linux and FreeBSD. If you are worried about bad RAM, ZFS is the only FS I would trust.

For what it's worth, it's my understanding that ZFS is no more or less susceptible to damage from RAM bitflips than any other filesystem.

@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.
NoSuck commented on 2015-01-12 21:00 (UTC)
@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.
graysky commented on 2015-01-12 20:56 (UTC)
Not a requirement, but recommended. I use zfs without ecc ram.
senorsmile commented on 2015-01-12 20:56 (UTC)
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!

This package will be kept in sync with the openzfs latest stable release and the kernels officially supported by it.
For the supported kernel versions, refer to the respective openzfs release notes (LINK).
E.g. openzfs 2.3.2 supports kernel versions 4.18 - 6.14. When kernel 6.15 is released for Arch, zfs-linux will not be updated until the openzfs project announces that it's compatible. This will most likely happen with the next openzfs release.
The kernel compatibility of the upcoming openzfs release can be seen in their META file (LINK).
For those wishing to use openzfs with unsupported kernels, do note that this could lead to serious issues, including data loss, even though such a zfs-linux package might build and install cleanly. Have reliable backups and use such a package at your peril.
Please do not mark this package as out of date without checking the kernel compatibility first. Thank you!
