AFAIUI, yes. If a single bit in the root's checksum is flipped just before being written to disk you'll probably lose the whole file system.

- empthought 11y agoYou understand incorrectly. http://arstechnica.com/civis/viewtopic.php?f=2&t=1235679&p=26303271#p26303271 http://arstechnica.com/civis/viewtopic.php?f=2&t=1235679&p=2... http://jrs-s.net/2015/02/03/will-zfs-and-non-ecc-ram-kill-your-data/ http://jrs-s.net/2015/02/03/will-zfs-and-non-ecc-ram-kill-yo... http://blog.brianmoses.net/2014/03/why-i-chose-non-ecc-ram-for-my-freenas.html http://blog.brianmoses.net/2014/03/why-i-chose-non-ecc-ram-f... etc.
- lomnakkus 11y agoCould you be more specific? You seem to just be linking to random posts about ECC vs. non-ECC. I don't see anything specifically there about the root of the file system. (I'll happily grant that this scenario is so unlikely as to be impossible for all practical purposes, but having skimmed the stuff you linked to I don't see why it couldn't happen theoretically.)
- ryao 11y agoIf I were creative, I could probably kill any filesystem with 1 bit flip if I could control the bit.
