Thanks for catching that - my statement was definitely too strong in implying data invulnerability.

I was hinting that you still get a bit of extra protection with ZFS over other filesystems, both on Non-ECC RAM. There is a chance with a stuck/corrupt bit that checksum will fail and you will get a read error. I interpreted OP as saying ECC is a must for ZFS, but I don't think you are more prone to corruption that any other FS?

I'm basing my understanding on this: http://jrs-s.net/2015/02/03/will-zfs-and-non-ecc-ram-kill-yo...
