Right now I am using raidframe RAIDs for some of my filesystems (/usr & /home). With the upgrade & subsequent good experience w/ ZFS on 2 other systems, I will probably switch to ZFS for this box as well. That brings up a question. There are many online URLs with dire warnings about using ZFS & non-ECC RAM causing data corruption (this box is a commodity desktop w/ non-ECC RAM), see for example: http://louwrentius.com/please-use-zfs-with-ecc-memory.html http://serverfault.com/questions/673163/why-is-the-use-of-zfs-without-ecc-ram-not-recommended & others, search for 'ZFS ECC' & you will be inundated. I am in fact using ZFS & non-ECC RAM on the other 2 boxen mentioned above, BTW. 2 questions: 1. Are these concerns valid, i.e. founded in fact ? 2. If so, should this be mentioned in the wiki or website somewhere ? TIA & have a good one. -- William A.
